Ten important safety tips for air travel

Air travel safety

Traveling by plane is one of the most pleasant and satisfying experiences you can have throughout your life. However, for everything to flow as expected, it is essential that you take preventive measures that effectively guarantee a fantastic day on board.

Going to other destinations, either for a few good days off or for work, usually generates positive expectations, especially when we don’t know the place.

How to carry pump on mountain bike?

How to carry pump on mountain bike

Carrying a pump on the mountain bike is always a tricky thing. But if you have the right tools, carrying a pump on a mountain bike becomes easier and you will be able to ride your bike all day without any problems.

How to carry pump on mountain bike? This is a common question among mountain bikers. Here are the most common ways that you can carry your pump while riding your mountain bike.

How to carry pump on mountain bike?

How to carry pump on mountain bike

With your two hands, grip the frame at both ends for a sturdy dragging position.

1 Carry pump with inflating tool and some hose: 

If you have got an inflator in your car or another accessory, then this will be useful, especially when checking puncture repairs in case of flats. There are also pumps that don’t require a battery, so you can use them while riding regardless of the sunshine light situation. 

2 You can also use a handlebar bag: 

This one looks like an entry-level version of the saddle bags. Most good quality pumps have their own handlebar mount that is low profile, making it less visible to thieves. Just make sure to move your gear pod off of it, so they don’t hassle you for being packrat and try not to ride with too much stuff? Also, read about bike frame size measurement.

3 There are special shoes from which you can hold pump just like below: 

So it is totally ok to clutch your bike for pumping then take a nice walk around town, only this time with an additional leg power source! And if you have such shoes but get rid of them midway through ride because of poor fit etc. Keep reading

4 Tango Pumps: 

This pump has two valves. That is, you can fill and also pour the air back out of the tire without stopping for pumping again!

5 Using a dynohub with saddle bag: 

This is useful when you need to carry small things like patches and other tools on the back of your bike. The best part about this kind of setup involves its easy maintenance, comfortability and also keeping heat away from the tires while traveling over long distances in July.

6 This one is a bit different: 

It hides the pump under your seat and at the trunk, thereby making it super-secret. When you lift the backside of the clamp with a flat tire, even someone who doesn’t know that there’s actually no hole in the rear wheel can notice this!

7 Here’s a bunch of inflatable tubes hanging below your seat:

The idea is to pull up shape while you’re riding, exactly like flapping your arms. The air inside will expand the tube, making it lose and deflate, leaving the valve open with a thin piece sticking out of the tire, which can grip on them for pumping and inflating when needed.

8 Here’s another way to fit multiple tubes:

They hide their pump (under the rando car) and crank it with a foot: The tool is mostly hidden as well. Pump repositioning also requires a super low profile – think Vespa scooter without license plate! No honking at other cyclists or worrying that you may run over something while pumping since your head will be on the invisible rear rack of your bike looking straight ahead.

9 One of the most efficient concepts utilizing a flat tire: 

Use it as a seat cushion! You can place your “toy” on the front wheel and ride without worrying about holding or balancing. For example, see how stylish this dog looks riding his youngster with a bike pump in the rear pocket. Pro tip: if you’re using a valve type that looks like the red circle below – don’t forget to provide back up for seating mode.

10 Mounted on the frame! 

Open up frame design allows you comfy standing while riding and enjoying the amazing view. Now all of these cycling modes are possible after we’ve put them in the flat tire!

Attach A Bike Pump To Your Bike

1 First of all – prepare pump, T-bolt (aka cycling valve tool), O ring and seatpost tube or adapter with the tire on it.

2 Without riding the bike, make sure the whole assembly is secure. Try inflating a car tire, so you know how hard to push your parts before using them in real world situations! Note that if you need a special attachment for DIY duct tape will not work: use double sided sticky tape instead of clear tape that allows air to pass through.

3 Install your pump to the valve handle and position it anywhere between the lower bracket and frame/fork.

4 For shorter (single tube) pumps – attach them directly above stem or shock if you have one of those normal looking ones with the horizontal knob.

5 For a longer DIY version, do this first off… Go slow here – make sure all parts are secured before each ride.

6 Thread tube over handle – it should have an angle that fits snugly around your stem and automatically locate the place where the valve will attach. If you do not trust this method, get axle adapter bits from the tubing shop or try other tools offered at Longacre Roadhouse in the riding gear section. You can then screw the tool to either frame or steer with a bar clamp – it all depends on how tight you like pumping. All parts included below are ready for long rides!

7 Now, choose the correct length for tube diameter and thread it through the handle – make sure you can push in all parts around the bike frame to avoid damaging any tubes.

8 Remove rocker protection spring from hardware spindle on the valve – hard wires work best.

9 Attach the valve handle to disk and thread disk between frame and shock if you have one with swing-arm or fork.

10 Insert normal seatpost tube in post area – use O ring as glue here! GO SLOW… your bike needs some cushioning around shocks. Please do not add too much length to these tubes, i.e., front shifters (I know I hate them!). The seat tube lever has a very hard time getting out of limits here if you try to do this before installing a wheel and spokes!

Once all is installed, simply tape in place as always or use glue. After firing up the bike to see how it breathes – pump till the pressure goes down comically low. Look for leaks around the stem rather than valve – clean parts with vinegar sprinkled on your hand and hose/sticky tape where needed. Adjust both bed-levelers.


Pumping is a great way to keep your tires inflated, but it can be tricky to do on the trail. This blog post explains how to carry a pump on your mountain bike and some of the ways you can use it.

  5. Wearing a bicycle helmet is important for your safety. It’s not only good for your safety, but it’s also good for your health.

When to change the bicycle helmet?

It is very common to buy a helmet and leave it there for years and years. That is wrong, and although it sounds like a myth, bicycle helmets expire. This is due to the fact that the material with which they are manufactured loses properties, hardens and protects worse from blows over time. On average, it is usually recommended to change the helmet every 5 or 6 years, even if they have not suffered any type of blow.

Of course, this figure is not absolute and can vary greatly. It is not the same to store the helmet in a place that is exposed to the sun every day, withstanding many changes in temperature, as in a place in the shade, but even so, change it every five or six years if you ride a bike frequently and if not, also. If you don’t go out much, you can bet on cheaper models so that it doesn’t hurt so much to pay for a new helmet.

If we have a hard fall, it is likely that the helmet has suffered structural damage (visible or not visible, be careful with this), so it has already fulfilled the purpose for which it was manufactured. If your helmet is cracked or has split, change it because it will no longer protect you.

The mission of a helmet is to protect our head from blows and if we bet on a manufacturer that meets the necessary safety standards, we will obtain similar protection in a cheap helmet and in an expensive one. So what is the difference between one and the other?

Although they protect the same, they are not as comfortable. An expensive helmet is lighter, it offers more air intakes to keep our heads cool, its visor is usually adjustable and the aerodynamics are improved. Aesthetic factors that have to be paid for or even extras such as hooks for GoPro cameras also come into play. All of this has to be paid for.

You yourselves can check the differences that I mentioned if you compare the blue helmet that you have two paragraphs above (economic model) compared to the IXS that heads this post and whose price is around 90 dollars. They have nothing to do with it.

Is cycling good for over 50s?

Is cycling good for over 50s

Workout for aging is something widely discussed. With aging comes new health concerns and with each concern, there is a need for new workout routines. Following the trend, cycling has become one of the most widely accepted sports for older people in Singapore. Usually, office workers look down on cycling as a mere form of transportation. But the real benefits of cycling are now becoming widely visible. Here are a few health benefits of cycling that are good to know if you are working on making good use of your exercise time.

Is cycling good for over 50s?

Is cycling good for over 50s

Cycling for over 50s is definitely a good idea. There are several health benefits of cycling that make it the perfect way to keep their minds active and active enough to maintain overall fitness levels in older adults. Most importantly, there are 10 things you should know if you decide on getting into this form of exercise. By following these tips, one can remain physically fit throughout his or her life by enjoying an exciting ride once they hit retirement age. Let’s discover the stationary bicycle stands.

Cycling for older adults is not a high-risk option. Most studies show that cycling at an intensity of less than 60% of VO 2 max produces no additional health problems. The effects on cardiovascular function are equivalent to walking or jogging, and the benefits seem particularly applicable in those with other physical limitations such as osteoporosis (loss of bone mineral content) which can adversely affect exercise performance by fatigue. Keep reading

Low impact exercise

Upper body and core muscle groups are activated in cycling. We may think that our biking regimen will be too easy to satisfy the needs of a poise, flexible older female (hips). But the truth is that there was ample research done by experts which showed an increase in dynamic hip extension during cycling as evidenced by EMG activity associated with agonist muscles like rectus femoris, adductor Magnus, vastus medialis obliqui as well as internal hip rotators. On the other hand, lower body muscle groups are also targeted in cycling. 

Exertion has been found to stimulate a heart rate increase of 24%, specifically within walking and running cycle ergometer protocols that involved pedaling at a cadence ranging from 70 rpms~120 rpm. Another University of Wisconsin Study examined high-intensity interval training versus moderate intensity steady state exercise on leg strength /kick power (i. e. Time to 40% of 1-RM) and found that the intermittent training had the greatest effects on all outcomes tested (Time, trial max squat jump power and muscular endurance ).

Group activity

Because the research has shown a lot about how beneficial cycling for older ladies may be, it is important to make us aware of further studies that prove this premise. A 2006 study from Denver University showed an overall significant gain in functional mobility, independent of age or activity level and also compared aerobic training with resistance training among community-dwelling unsheltered elderly population (>65y). The recovery effects were greatest within the first month, while at 1 year time-point, strength levels of slow-twitch type II muscle fibers were also significantly higher in the physical training group. 

Another study that used strength and aerobic testing of senior women. Found improvements after a 6 months exercise program with cycling being most effective compared to walking or skipping rope – while 3hr/day sessions showed better gains than shorter, less frequent exercises although not statistically significant (Number and repeats performed per session did matter but maybe a limitation). 


When it comes to female cycling, the research is very limited and some of these studies just don’t seem to include anything like Wingate or Cyclus tests. Nevertheless, interestingly enough, this issue has been studied by a group at Stanford University who looked into Aerobic vs Respiratory Models – are our muscles more ‘Blood-Thinner’ (Respirer) than we think? 

We’ve also asked what type of workouts make women burn as much fat as men? We are excited to learn that there is some actual evidence out there. A recent study done at the University of Zagreb in Croatia looked into women who did ‘endurance training’ by cycling on a stationary bicycle at strenuous or moderate intensity levels repeatedly over what they call practically every single day for ~6 weeks showed females (and males) gained significantly more fat from their cycling than their sedentary control counterparts.

Cardio & strength workout

Females are believed to be less efficient at using oxygen (or, more specifically, our O2 content in the blood) during aerobic exercise than males. The researchers concluded that females should focus on cardiovascular activities such as running, cycling and swimming. Meanwhile, males are suggested to elevate their intensity through higher repetition efforts while the factor of volume is less critical in female athletes since more reps per session yield a greater gain in strength than increased work rate or heart rate between sets.

Sharpen our mind

Another interesting study was done at Louisiana State University, which looked into the benefits that engaging in sports can have on girls’ mental performance. What did they find? After being randomly split up into one group that engaged with team activities and another control group, researchers found those in the interest prepared task (IT) improved after a workout while those without improvements gained no significant benefit from participation. The results seem to support over 16 years ago when it was noted young women are more likely to participate in team sports than their male counterparts. They are also better able to handle the stress and pressure that are associated with leadership positions.

Look & feel younger

To add some icing to the cake, just as we see in aging sports personalities slacking off over their age and looking beat up, so too are exercising teens likely to look more tired than their exercisers’ counterparts of the opposite sex. In what seems to be yet another prophylactic measure against anti-aging problems (as opposed to an improvement), increased physical activity has also been shown to produce a noticeable skin complexion alteration without having any effect on the overall facial and body line.

Cycling is a great way to stay fit and active as you age. It’s an excellent form of exercise that can help improve your balance, coordination, and cardiovascular health. However, the simple act of pedaling a bike will not be enough to keep you healthy if you’re past 50 years old. The best way to get started with cycling is by choosing the right bike for your age and fitness level.

How to ride a cruiser bicycle?

How to ride a cruiser bicycle

If you want to learn how to ride a cruiser bicycle, you need to know how to ride a regular bike first. Cruisers are different from regular bicycles. You can try schwinn women’s cruiser. They have longer, lower handlebars, smaller wheels, and a slightly different frame. However, you can still learn how to ride a cruiser by following these steps.

How to ride a cruiser bicycle?

Disadvantages of the cruiser bicycle

  1. It’s not very fast: This is the first thing that people notice about the cruiser bike. They’re not as fast as other bikes. This means they’re not very suitable for sports or competitions.
  2. It’s not very stable: The cruiser bike doesn’t have a lot of stability, so it’s not suitable for riding on rough terrain.
  3. It’s not very comfortable: The cruiser bike doesn’t have a lot of comforts, so it’s not suitable for long rides.
  4. It’s not very durable: The cruiser bike isn’t as durable as other bikes, so it’s not suitable for regular use.
  5. It’s not very practical: The cruiser bike doesn’t have a lot of practicality, so it’s not suitable for everyday use.

Safety tips for riding a cruiser bicycle

  1. Check the weather: It’s always best to check the weather before riding your bike. Make sure you know what the weather is going to be like so you can plan accordingly. If you’re planning on riding your bike in the rain, make sure you have a raincoat or umbrella.
  2. Always wear a helmet: This might seem obvious, but wearing a helmet is important. Not only does it protect your head, but it also makes you look more confident when you’re riding your bike. You can find helmets for all different types of bikes, including cruiser bicycles.
  3. Wear bright clothing: Wearing bright clothing will make you more visible. You don’t want to be riding in the dark, so make sure you wear something that’s easy to spot.
  4. Don’t ride in the middle of the road: You’ll want to ride on the side of the road and not in the middle of the road. It’s important to know where you’re going and where other vehicles are. This will help you to avoid getting into an accident.
  5. Use traffic lights: It’s important to use traffic lights if you’re riding on a busy road. You’ll want to stop at red lights and use them when you’re turning right or left. This will help to avoid accidents.
  6. Don’t ride fast: If you’re riding a cruiser bicycle, you don’t want to ride fast. You don’t want to ride too fast, as it can make you feel like you’re being chased by something.
  7. Don’t ride on sidewalks: You can find many laws about riding on sidewalks. Make sure you follow them and stay on the bike lane.
  8. Look both ways before you cross the road: It’s always important to look both ways before you cross the road. It’s not always safe to cross the road. It’s important to be aware of your surroundings and to look for cars and other vehicles.
  9. Use hand signals: If you’re riding with other people, you’ll need to use hand signals. You’ll want to use them to show others that you’re going to turn right or left.
  10. Ride in groups: It’s important to ride in groups. This will help you to avoid accidents, and it will also help you to feel more confident when you’re riding your bike.

In conclusion, a cruiser bicycle is a type of bicycle that has an upright riding position. The name comes from the fact that it was originally designed for long-distance touring, and it is usually fitted with a wide front tire that makes it easier to balance while pedaling. A cruiser bicycle is generally larger than a standard road bicycle and has a longer wheelbase and lower frame.

Bicycle greases and lubricants: The complete guide to use

Bicycle greases

Being a purely mechanical means, the components of a bicycle are subjected to friction, rolling and metal-on-metal clutches, which must be attenuated through the use of greases and lubricants. The main task of lubrication is precisely to reduce the frictional wear of the components, protect them from atmospheric oxidation, from washing out with water, and prevent excessive heating.

Lubrication, in the world of bicycles, can be divided into two main categories:

  • Lubrication with grease;
  • Lubrication with oils.

Knowing the characteristics, the types and the mechanical philosophy that underlies these is part of the ABC of a good mechanic and passionate cyclist. You can go through the Mongoose mountainbike.

What is it for?

Lubricating with grease is mainly used to protect bearings and balls subjected to rolling and friction, to protect them from water washout and dirt that cause premature wear.

Where it applies

Where there are bearings, then headsets, bottom brackets, wheel hubs. Furthermore, it is good practice to protect the threads with grease to avoid seizing.

Characteristics of bicycle greases

By lubricating grease, we mean a viscous substance (therefore not purely fluid), composed of a mineral or synthetic oil base, with specific additives for the applications for which the lubricant is intended. It follows from this that a “milieus” grease that is efficient in all conditions of use cannot exist. On the market, there are some that have a large range of applications, but if you want to keep your bike at its best, it is advisable to prefer special greases. The main characteristics of bicycle grease are:

  • Good viscosity to resist centrifugal forces;
  • Resistance to water washout and dirt;
  • Ability to activate at low operating temperatures

Additive: Component added to the oil/soap base mixture to give the grease certain characteristics

Dropping point: Temperature beyond which a grease becomes more fluid and begins to drip, losing its lubricating characteristics. Once the dropping point is reached, the fat is compromised even if it is allowed to cool.

Viscosity: Characteristic of the molecules of a material to move away from each other. The higher the viscosity of grease, the less fluid it appears.

The ability of the grease or lubricant to activate its characteristics in certain situations or temperatures

What grease to use?

The typical lubricating grease that you can find just a few euros from the hardware store or even in non-specialized stores. It is an emulsion of mineral oil and soap, usually with added calcium, sodium, or barium.

Lithium grease

It is a lithium-based lubricating grease, usually white in color. It is widely used in the nautical industry as it is anti-seize and very resistant to the washing action of water. It can be used on bearings in headsets, bottom brackets, and hubs. It can also be used for the installation of threaded components thanks to its anti-seize characteristic.

Copper grease

Copper grease is an excellent anti-seize agent that is used in the mechanical industry for tightening bolts and coupled joints that work at high temperatures. The bicycle products called “anti-seize” (i.e., anti-seize) are nothing more than specific lubricants based on copper grease. It can be put on the bottom bracket caps, on the seat post, on the pedal pins, and on all components that are coupled by threading (spreading a light film on both the screw and the nut screw). In this way, micro-welding of the threads is avoided, which causes them to seize.

Teflon grease

Polytetrafluoroethylene, called Teflon or PTFE, is a synthetic polymer characterized by high resistance to chemical aggression and a very low coefficient of friction. Added as an additive to the lubricating grease, it makes it suitable for all those applications that require smoothness, elimination of friction, attenuation of noise. It is an excellent grease for components of a bicycle that work by friction, such as bearings. Not to be used on threaded parts, as it would increase the smoothness of the threads and therefore the possibility of loosening.

To be avoided

The one pictured is an old but common automotive type grease. Car bearings work at much higher temperatures and rpm than a bicycle. Automotive greases, therefore, activate at too high temperatures and would remain “inert” on a bicycle.

Even silicone grease, despite its high resistance to washout, is too liquid to be used on a bicycle (you risk having leaks). It is also not suitable for bearings.

How to apply the grease

There are various methods. The one-time mechanic took his index finger, dipped it in the jar of grease, and then passed it over the fillets. It is an immortal method, but sometimes it is difficult to reach the most uncomfortable points, such as the hub tracks and you risk greasing a much more abundant part than that affected by maintenance. You can use a brush dipped in grease or special guns with a pointed beak. In this case, even the most uncomfortable points are reached very easily. You do not get dirty. You apply the grease only where it is needed and waste is limited.

Lubrication with oily lubricants: What it is for

To decrease the friction and, therefore the wear of the components that work by rubbing or rotation. It also serves to create a protective barrier against the atmospheric agents to which all these components are exposed.

Where does it apply?

Chain, front and rear derailleur, cassette and sprocket set, fork legs, brake pins at the fulcrum. Important, never grease the chain!

Characteristics of bicycle lubricants

A bicycle lubricant must be free of hydrocarbons and solvents that are aggressive to metals, have excellent resistance to dirt and water, resist centrifugal force, and be fluid enough to be able to penetrate into very small areas (such as chain rollers)

What lubricant to use?

A neophyte or a superficial mechanic might think that on the chain, it is enough to spray any lubricant with characteristics that guarantee fluidity of movements and protection from rust.


I’m talking about the very famous WD-40 or Svitol, a panacea for all squeaks. In reality, more than a lubricant, the WD40 has a cleaning action (for this reason, it descales the seized threads). In fact, the lubricant inside the spray is a small part, which evaporates and does not protect the chain. I do not recommend it, since it is always better to rely on products designed and studied for use on a bicycle. Absolutely not to be used on the fork legs, as it is composed of a percentage of hydrocarbons that could cause the oil seals to dry out. Only specific products must be used on the suspension forks.

Dry (or dry) lubricant

Let’s make a distinction: the division between dry and wet lubricant does not necessarily mean that the former should be used when it is sunny and the latter when it rains. This is a conception error, as the terms “dry” and “wet” indicate the composition of the lubricant. The former is, in fact, drier while the latter is more viscous. The dry lubricant has Teflon additives, allows a good sliding of the chain and does not make the dust stick to the metal (which would have an effect similar to sandpaper on the components). It has a fairly limited duration and resistance to water washout is low. In fact, it tends to evaporate in a short time and for this reason, it should be added after a certain number of kilometers. It is an excellent solution for short rides, where there is not too much mud or humidity.

Wet lubricant

Designed to be vicious and thick, wet lubricant works in a totally opposite way to dry lubricant. In this case, the lubricant is viscous, almost sticky (a characteristic due to the silicone additives), to remain “clinging” to the chain and ensure that the water does not wash it away quickly. It tends to knead the chain, as it can attract dust or dirt, but once it gets into the pins, it stays inside for a long time. It is an excellent solution for long rides, where you don’t have time to stop and re-lubricate (which you should do if you are using a dry lubricant).

Suspension lubricant

The suspension stems (both front and rear) of the Mtb must be lubricated so that they slide better inside the chainstays. In this case, my advice is to always use specific lubricants for this type of work. In fact, the lubricant must give smoothness to the stem, keep it clean so that dirt does not stick (which would seriously wear the stems, even scratching them), do not dry out the oil seals, and do not contaminate the oil of the suspension hydraulics when the stem goes into compression in the sheath. Using an unsuitable lubricant would lead to one of the problems mentioned above, with what follows (suspensions cost a lot). Another mistake to avoid is to lubricate without first cleaning the stems with alcohol and a cotton cloth.

How to apply the lubricant

Easy: I turn the chain at full throttle, spray a liter of lubricant and start again with the chain dripping oil. Of course, you can do it if you want to harm your bike.

Let’s start by saying that it is better to use the lubricant in a bottle rather than the spray one, since it is easier to lubricate in the right places, not to dirty the rest of the bike with the jet, use the necessary amount. It is also good for the environment.

First, you have to clean the transmission thoroughly with a detergent. If very dirty, it should be disassembled and washed with white petroleum. Then the chain is slowly turned and lubricated by dropping a small amount on each roller of the chain (i.e., on the pin that holds the links together). If you consider that the chain has more than one hundred rolls, you understand why I said that it is a “pugnacious” operation. After lubricating the chain, downshift all the ratios of the rear cassette and the front crankset so that the lubricant has a way to penetrate inside the rollers. Then take a rag in your hand, wrap it around the chain and spin it. This is done to remove excess lubricant. In fact, it is a common belief that “the more lubricant the better,” but this is a misconception. Excess lubricant will clog the transmission,

When lubricating the transmission, protect the disc brake rotor with a cloth or plastic bag. If some lubricant ends up on the rotor, it could then contaminate the pads, canceling the braking effect and very dangerous during use. You may also like to read Bike brakes quick and easy tips

Give Them More Fluids

Should hydration be increased in summer? “Yes, due to the increase in ambient temperature. In addition, children spend more hours in the sun, perform more physical activity with sweat production and play a lot outdoors”, explains Dr. Antonio Redondo, a pediatrician at the Vithas Medimar International Hospital in Alicante.

Watch For Dehydration

As explained by Dr. Antonio Redondo, the warning symptoms that the child is dehydrated are pale skin and dark circles under the eyes due to the lack of fluid in the skin. At first, there is also irritability and if it progresses, decay. In babies who still have an open fontanelle, it sinks.

Protect Them Against Heat Stroke

As Dr. María Jesús Pascual points out, “ children under one year of age are the most sensitive to heatstroke. Keeping a child in a closed car, even for a short time, exposing himself to the sun in very hot hours, or doing intense exercise without adequate hydration are situations that favor heat stroke.

«In summer the diet should be as always: varied and balanced. It is advisable to monitor the tendency to snack and consumes non-nutritious foods”

Apply Sunscreen Well

Sunscreen should be applied before the child puts on a bathing suit and at least half an hour before sun exposure. The ideal is to spread the cream at home on all areas, without forgetting any (ears, hands, nose, neck…). It is important to extend it correctly (making circles) and renew it at least every two hours. The cream is not only used on sunny days but also on cloudy days.

Take Care Of The Skin In Case Of Burns

As recommended by Dr. Antonio Redondo, when a child suffers burns, the first thing is “to get him out of the sun, take care of the affected skin with an after-sun; and if he has blistering lesions, seek medical attention and offer fluids.”

Control Sun Exposure

Should children wear a shirt when they are on the beach? “No. Wearing clothing can give a false illusion of protection from ultraviolet rays. Light colors offer less sun protection. In very sunny places, and especially at noon and when there is a lot of sunshine, children should be completely avoided exposing themselves to the sun ”.

Alert Against Secondary Drowning

“When a child or an adult drowns in fresh or saltwater and responds well to cardiopulmonary resuscitation maneuvers, they remain apparently ‘normal’, but there is a period of between 1 and 72 hours in If the water has reached the alveoli of the lungs, lung function can be compromised and symptoms of ‘secondary drowning’ can occur: shortness of breath, intense coughing, extreme tiredness, and brain damage. For this reason, after drowning, the patient should be kept under observation in a hospital”, explains Dr. Antonio Redondo, a pediatrician at the Vithas Medimar International Hospital in Alicante.

Dry Your Ears Well

The basic precautions to avoid otitis from swimming pools that many children suffer from are, according to Dr. Antonio Redondo, “dry your ears well when you get out of the water with a towel and tilt your head to both sides to try to get out the water that has entered”. In addition, ” in susceptible children, bathing time should be reduced, earplugs and bathing caps should be used, and a few drops of a diluted alcohol solution can be put on when leaving the water.”

In The Water, Always Supervised

Drowning is the second most frequent cause of death in children under nine years of age, which is why children must always be supervised in the pool. Experts advise teaching them to swim early (from the age of four), but even so, you have to control them visually.

“Should children wear a shirt when they are on the beach? “No. Wearing clothing can give a false illusion of protection from ultraviolet rays.

Beware Of Diving

5% of spinal cord injuries occur when diving into a pool, lake, or sea. It usually happens especially among the adolescent population, so extreme care must be taken: always checking the bottom beforehand and not diving headfirst.

Fungal infections in swimming pools are also very common in summer. The basic guideline to avoid them is to always wear shoes in wet areas and where water puddles, such as in showers. When you get out of the water, you have to insist on drying between your fingers. The fungus can also grow from keeping the swimsuit wet for a long time when you get out of the water.
