The benefits and harms of ultraviolet rays of sunlight on the human body and skin: how to provide protection when tanning

The sun's ultraviolet rays give life to all life on our planet. If at one moment the ultraviolet rays of sunlight disappear, then all the processes of photosynthesis will immediately stop, a terrible cold will come, the light will disappear. The real "end of the world" will come.

And all this importance, scientists are constantly questioning the positive biological effect of ultraviolet rays, theories are being built that this is harmful radiation. Indeed, some facts suggest that the action of ultraviolet rays on the body leads to the development of pathological processes. But basically, if you follow the recommendations of dermatologists, even a tan is useful procedure. After all, only under the influence of ultraviolet rays in the human body is produced irreplaceable vitamin D. Without it, the destruction of bones begins and the process of absorption of calcium is impossible.

Needless to say, how we all aspire to the beach in summer to enjoy swimming and sunbathing? AT last years Scientists have greatly expanded their understanding of the effects of sunlight on the skin. And the more information about this appears, the louder they urge us to be careful. Abuse of sunbathing is fraught with serious consequences. Regular intensive tanning leads to premature aging: the appearance of wrinkles, unhealthy skin color, burns, irritation, and most dangerously, an increased risk of skin cancer. So why not prevent negative consequences in a timely manner?

Types, types and proven properties of ultraviolet rays

It is widely known that there are several types of ultraviolet rays. UVA and UVB radiation are two different types of solar radiation. UVA types of ultraviolet rays penetrate deep into the skin, reducing its elasticity and firmness, causing premature aging of the skin, which is expressed in the accelerated formation of wrinkles, age spots and freckles, especially in fair-haired and light-eyed people. These rays can also cause skin cancer.

UVB rays are much more energetic than UVA rays. They cause sunburn and are one of the most common causes occurrence of skin cancer. It should be remembered that UVA and UVB rays have a harmful effect on the skin even in cloudy weather! Various creams protect against UVB, and nutritional supplements increase internal resistance to UVA radiation. The scientifically proven properties of ultraviolet rays have both beneficial and harmful effects on the human body.

Of course, you noted that older people, who are used to protecting themselves from the sun with umbrellas and wide-brimmed hats, have much smoother and softer skin than their peers - sailors, gardeners and representatives of other professions whose work involves being outdoors in any weather. and at any time of the year.

But do not consider the sun as your enemy! In moderate doses, it prevents the occurrence of rickets and seasonal depression, helps fight psoriasis and, according to anecdotal evidence, breast and colon cancer.

Thanks to the sun's rays, our body produces vitamin D, which is necessary for strengthening the skeleton, and hormones Have a good mood. Among other things, the sun's rays are an excellent natural pain reliever.

However, do not forget that the possibilities of sunlight- a double-edged sword. Do you know that sunburn Isn't it just ugly and painful? This is a real burn with a deep skin lesion, which requires no less treatment than household one.

7 bad news about the dangers of the sun

The benefits and harms of ultraviolet rays have not yet been thoroughly studied, so scientists are building hypotheses. There are currently 7 bad news for modern man about the dangers of the sun:

To provide effective protection against ultraviolet rays, doctors have developed special recommendations. They are listed further down the page.

Did you get sunburn? Take 500mg rose nutmeg oil capsules 3 times daily for 20 days.
"How many times have they told the world": protect yourself from the sun's rays! And all the same, adults and children sunbathe on the beach for hours in the heat! A classic example of frivolity and irresponsibility!
Careless exposure to the sun will inevitably affect the state of health. Deep wrinkles, redness, cataracts, degenerative spots, skin cancer - these are far from complete list possible consequences. Not to mention that the sun's rays are the most powerful factor accelerating aging. UVB rays destroy the skin, and penetrating UVA rays damage the cells that make up the skin. Don't forget: sunscreens/sunscreens only protect against UVB rays!
The best way to protect the body from the effects of ultraviolet rays on the body is a shade, and it doesn’t matter what helps in this - the wall of the house, an umbrella, a beach fungus, a wide-brimmed hat or sunglasses ... Irreplaceable helpers will be a T-shirt, windbreaker or pareo. And, of course, a protective cream that needs to be lubricated on all exposed surfaces, including ears and toes.
A balanced diet is another remedy for ultraviolet rays and a faithful assistant. Proper nutrition not able to protect against sunburn, but it will help strengthen the body's defenses. Eat more olive oil, exotic fruits and apricots, vegetables (especially tomatoes) and legumes. Limit your consumption of meat, dairy products (including butter) and sweets.

Beware of the influence of ultraviolet rays on the body of the alpine sun - it is the most aggressive. When sunbathing on a sea beach, do not forget that the sun's rays reflected by the water surface, combined with a light and so pleasant sea breeze, are fraught with great danger.
Snow also reflects the sun beautifully, increasing UV radiation by 10% for every 1,000 meters. And this means that the higher you climb in the mountains, the more likely you are to get a sunburn. Moreover, if the sand reflects 10% of the sun's rays, and the water surface 20%, then freshly fallen snow reflects 90% of the sun's rays. Thus, the dose of UV radiation that your eyes and skin receive is multiplied many times over.
So how can you protect yourself from the influence of ultraviolet rays on a person: sunscreens, covering the body with a thin protective film, create a certain barrier that limits the sun's rays on the skin. This method of protection is only effective if you apply sunscreen to all exposed surfaces every 2 hours of sun exposure. However, the first manifestation of a tan indicates that UV rays have finally reached your skin! Remember that they cause significant harm to the body, enhance oxidation processes that accelerate cell aging. Taking sunscreen nutritional supplements that supply the body with the necessary antioxidants allows you to fight these processes from the inside. Among other things, nutritional supplements are aimed at preventing oncological diseases, prevent the occurrence allergic reactions in the sun (summer radiation dermatitis). No sunscreen can do this! Taking 1-2 capsules per day will provide reliable protection in summer period! In addition, taking the right nutritional supplements speeds up the time of obtaining a beautiful tan and makes it more long-lasting, moisturizing the skin and keeping it soft from the inside.

All devices for artificial tanning, standing in beauty salons and solariums, cause irreparable harm to health. Long years dermatologists around the world are doing everything possible to achieve a ban on their use. If you need to look tanned, it is better to use self-tanning products that do not burn or dry the skin. Opt for gel forms that contain fewer hazardous ingredients. However, in the presence of millet, freckles or enlarged pores, it is not recommended to use self-tanning products.
Self-tanning products do not interfere with tanning, and therefore do not protect the skin from harmful effects sun rays.
Use sunscreen with an SPF of at least 30 daily. Apply sunscreen several times a day, especially after swimming or if you sweat excessively, even if the bottle is labeled "waterproof".
Drink more water: The summer rate of fluid intake ranges from 1 to 2 liters per day.
Don't confuse sun exposure with heat exposure. Ultraviolet rays do not cause a feeling of heat and retain their harmful effect on the body even at 40 ° C. It is necessary to protect yourself from the sun from the very first solar spring days when the air is still quite cool. In the period from the beginning of June to the end of September, it is advisable to use daytime or foundation creams with the appropriate SPF. SPF is a sun protection factor that refers to the ability cosmetics increase the time of safe exposure to the open sun. The value of the SPF factor can be in the range from 2 to 50 units. It is calculated in special laboratories, based on the fact that a certain agent will be used in an amount of 2 mg per 1 sq. see skin surface. Most often, sunscreens and lotions are produced with an SPF value, as well as day creams, foundations, powders, lipsticks and lip balms.

Don't forget to put sunscreen on your ears.
Don't rely on being in the city to save you from the harmful rays of the sun. The sun combined with polluted air is much more dangerous.
For children, the sun's rays are hundreds of times more dangerous, so protect them from the sun. Remember that for a child, the dose of ultraviolet rays of the sun received in 4 minutes is equivalent to the dose that an adult receives in 1 hour.
Do not think that solar radiation is most dangerous between 12 and 16 hours. In this interval there is greatest intensity UVB rays, while the rest of the time we are attacked by UVA rays.
Don't consider yourself invulnerable. The use of sunscreens and nutritional supplements helps protect against the sun, but common sense suggests that in addition to this, sunglasses, a hat and a T-shirt are needed.

Man cannot live without sunlight. The sun gives us joy and helps us stay healthy. The sun's rays affect the production of serotonin, which improves mood and performance. They are necessary for the synthesis of vitamin D3, which is important for bones, without which calcium cannot be absorbed in the body.

In fact, what in our minds is considered the "sun", in fact, is just not the most most of. The human eye can only distinguish 40% of the sun's rays. The "invisible" Sun is infrared radiation (50%) and ultraviolet (10%).

Types of sunbeams:

1.Ultraviolet (UVC, UVB, UVA)
I) UVC - do not reach the Earth's surface, are completely absorbed by the upper atmosphere.
II) UVB - do not pass beyond the epidermis, cause a permanent tan.
III) UVA - penetrate the dermis, cause an "instant tan", which appears immediately after exposure to the sun and quickly disappears.

2. Infrared (IR-A, IR-B, IR-C) - thermal radiation of the Sun. IR-A rays are able to penetrate into the hypodermis, subcutaneous fat.

Do you remember the rhyme about "Every hunter wants to know where the pheasant sits"? Violet ("pheasant") is the last visible part of the solar spectrum, beyond which ultraviolet begins. Red ("every") is the first color of the solar spectrum available to our vision, preceded by invisible infrared rays.

Different types sun rays differ from each other in important physical characteristic- wavelength, which determines their properties.

UVB rays practically cannot penetrate normal glass. UVA and IR rays penetrate glass easily. Therefore, sitting by a closed window on a hot day is impossible to get a tan, but you can get a heat stroke.

Infrared rays are unable to penetrate water. 60% of UVB and 85% of UVA rays penetrate to a sufficient depth. Therefore, being in a pond, we do not feel the heat, but we can get a sunburn.

Doctors do not recommend to be long time in the sun without the use of solar cosmetics. It is needed not only during a trip to the sea or excursions in the desert, but also when you are simply on the road for a long time. fresh air: gardening, walking, skiing or cycling. Solar cosmetics will save you from troubles, the source of which can be the sun's rays.

UVB rays can cause burns and the appearance of age spots on the skin. UVA rays damage collagen and elastin fibers, causing the skin to lose firmness and elasticity.

Infrared A-rays for a long time considered harmless. However, studies conducted at the University of Düsseldorf in 2003 showed that IRA rays, when exposed to human skin, lead to the formation of free radicals that destroy collagen fibers, leading to premature aging. Ladival was the first to use a patented formula with antioxidants to protect against the harmful effects of IRA rays in solar cosmetics. Its effectiveness has been clinically proven.

5 facts about the Sun:

1. The word "Sun" in English language is an exception: it has the form of a personal pronoun and refers to the masculine gender - "He".

2. Lack of sunlight can cause mental disorder- winter depression (Seasonal Affective Disorder). Its symptoms are drowsiness, lethargy, irritability, a feeling of hopelessness, anxiety.

3. The mass of the Sun is 99.85% of the mass of the solar system. The share of its other objects accounts for only 0.15%.

4. About 1 million planets, the size of the Earth, could fit inside the Sun.

5. The force of attraction on the Sun is 28 times greater than the force of attraction on the Earth: a person who is on Earth weighs 60 kilograms on the Sun would weigh 1680 kilograms.

The sun plays an important role for us on Earth. It provides the planet and everything on it with important factors such as light and heat. But what is solar radiation, the spectrum of sunlight, how does all this affect us and the global climate in general?

What is solar radiation?

Bad thoughts usually come to mind when you think of the word "radiation". But solar radiation is actually very a good thing- it's sunshine! Each creature on earth depends on him. It is necessary for survival, warms the planet, provides food for plants.

Solar radiation is all the light and energy that comes from the sun, and there are many different forms of it. In the electromagnetic spectrum, there are different types light waves emitted by the sun. They are like the waves you see in the ocean: they move up and down and from one place to another. The spectrum of solar study can have different intensities. Distinguish between ultraviolet, visible and infrared radiation.

Light is moving energy

The spectrum of solar radiation figuratively resembles a piano keyboard. One end of it has low notes, while the other end has high notes. The same applies to the electromagnetic spectrum. One end has low frequencies and the other end has high frequencies. Low frequency waves are long for a given period of time. These are things like radar, television and radio waves. High-frequency radiations are high-energy waves with a short wavelength. This means that the wavelength itself is very short for a given time period. These are, for example, gamma rays, x-rays and ultraviolet rays.

You can think of it this way: low frequency waves are like going up a hill with a gradual rise, while high frequency waves are like going up a steep, almost vertical hill quickly. The height of each hill is the same. The frequency of an electromagnetic wave determines how much energy it carries. Electromagnetic waves that are longer and therefore lower frequencies carry much less energy than shorter wavelengths and higher frequencies.

This is why x-rays can be dangerous. They carry so much energy that if they get into your body, they can damage cells and cause problems like cancer and DNA changes. Things like radio and infrared waves, which carry much less energy, don't really have any effect on us. This is good, because you certainly don't want to put yourself at risk by simply turning on the stereo.

Visible light, which we and other animals can see with our eyes, is located almost in the middle of the spectrum. We don't see any other waves, but that doesn't mean they aren't there. In fact, insects can see ultraviolet light, but not our visible light. Flowers look very different to them than they do to us, and this helps them know which plants to visit and which ones to stay away from.

Source of all energy

We take sunlight for granted, but it doesn't have to be, because, in fact, all energy on Earth depends on this large, bright star at the center of our solar system. And while we're in it, we should also say thank you to our atmosphere, because it absorbs some of the radiation before it reaches us. It's an important balance: too much sunlight and the Earth gets hot, too little and it starts to freeze.

Passing through the atmosphere, the spectrum of solar radiation near the surface of the Earth gives energy in different forms. To begin, consider various ways her transmissions:

Conduction (conduction) is when energy is transferred from direct contact. When you burn your hand with a hot frying pan because you forgot to put on an oven mitt, that's conduction. The cookware transfers heat to your hand through direct contact. Also, when your feet touch the cold tiles in the bathroom in the morning, they transfer heat to the floor through direct contact - conduction in action.
Dissipation is when energy is transferred through currents in a fluid. It can also be gas, but the process is the same anyway. When the liquid is heated, the molecules are excited, dispersed and less dense, so they tend to rise. When they cool down, they fall down again, creating a cellular flow path.
is when energy is transmitted in the form of electromagnetic waves. Think about how good it is to sit next to a fire and feel the welcome warmth radiate from it to you - that's radiation. Radio waves, light and can travel by moving from one place to another without the help of any materials.

The main spectra of solar radiation

The sun has different radiation: from x-rays to radio waves. Solar energy is light and heat. Its composition:

6-7% UV light,
about 42% of visible light,
51% near infrared.

We receive solar energy at an intensity of 1 kilowatt per square meter at sea level for many hours a day. About half of the radiation is in the visible short-wavelength part of the electromagnetic spectrum. The other half is in the near infrared, and a little bit in the ultraviolet part of the spectrum.

Ultraviolet radiation

It is ultraviolet radiation in the solar spectrum that has an intensity greater than others: up to 300-400 nm. Some of this radiation that is not absorbed by the atmosphere produces sunburn or sunburn for people who have been in sunlight for long periods of time. UV radiation in sunlight has both positive and negative health effects. It is the main source of vitamin D.

Visible radiation

Visible radiation in the solar spectrum has an average intensity. Quantitative estimates of the flux and variations in its spectral distribution in the visible and near infrared ranges of the electromagnetic spectrum are of great interest in the study of solar-terrestrial impacts. The range from 380 to 780 nm is visible to the naked eye.

The reason is that the bulk of the energy of solar radiation is concentrated in this range and it determines the thermal equilibrium of the Earth's atmosphere. Sunlight is key factor in the process of photosynthesis used by plants and other autotrophic organisms to convert light energy into chemical energy that can be used as fuel for the body.

Infrared radiation

infrared spectrum, which spans from 700 nm to 1,000,000 nm (1 mm), contains an important part of the electromagnetic radiation that reaches the Earth. Infrared radiation in the solar spectrum has three types of intensity. Scientists divide this range into 3 types based on wavelength:

A: 700-1400 nm.
B: 1400-3000 nm.
C: 3000-1mm.

Conclusion

Many animals (including humans) have sensitivity in the range of about 400-700 nm, and the usable color vision spectrum in humans, for example, is about 450-650 nm. In addition to the effects that occur at sunset and sunrise, the spectral composition changes primarily in relation to how directly sunlight hits the ground.

Every two weeks, the Sun supplies our planet with enough energy to last the whole year. In this regard, solar radiation is increasingly being considered as an alternative source of energy.

Talking about the influence of the sun on human body, it is impossible to accurately determine the harm or benefit it brings. The sun's rays are like kilocalories from food.. Their deficiency leads to malnutrition, and in excess they cause obesity. So it is in this situation. In moderate amounts, solar radiation has a beneficial effect on the body, while an excess of ultraviolet radiation provokes burns and the development of numerous diseases. Let's take a closer look.

Solar radiation: general effect on the body

Solar radiation is a combination of ultraviolet and infrared waves.. Each of these constituent parts affects the body in its own way.

Influence of infrared radiation:

The main feature of infrared rays is the thermal effect they create. Warming up the body contributes to the expansion of blood vessels and the normalization of blood circulation.
Warming up has a relaxing effect on the muscles, providing a slight anti-inflammatory and analgesic effect.
Under the influence of heat, metabolism increases, the processes of assimilation of biologically active components are normalized.
Infrared radiation from the sun stimulates the brain and visual apparatus.
Synchronization occurs due to solar radiation biological rhythms organism, sleep and wakefulness modes are launched.
Treatment solar heat improves the condition of the skin, eliminating acne.
Warm light uplifts and improves emotional background person.
And according to recent studies, it also improves the quality of sperm in men.

Despite all the debate about the negative impact ultraviolet radiation on the body, its deficiency can lead to serious problems with health. It is one of the vital factors of existence. And in conditions of ultraviolet deficiency in the body, the following changes begin to occur:

First of all, immunity weakens. This is caused by a violation of the absorption of vitamins and minerals, a malfunction in metabolism at the cellular level.
There is a tendency to develop new or exacerbate chronic diseases, most often occurring with complications.
Lethargy, chronic fatigue syndrome are noted, the level of working capacity decreases.
The lack of ultraviolet light for children interferes with the production of vitamin D and provokes a decrease in growth.

However, you need to understand that excessive solar activity will not benefit the body!

Sunbathing contraindications

Despite all the benefits of sunlight for the body, not everyone can afford to enjoy the warm rays. Contraindications include:

acute inflammatory processes;
tumors, regardless of their location;
progressive tuberculosis;
angina pectoris, ischemic disease;
endocrine pathologies;
damage to the nervous system;
dysfunction of the thyroid and adrenal glands;
diabetes;
mastopathy;
uterine fibroids;
pregnancy;
recovery period after surgery.

In all cases, active radiation will aggravate the course of the disease, provoking the development of new complications..

Do not get involved in the sun and the elderly, infants. For these categories of the population, treatment with sunlight in the shade is indicated. The necessary dose of safe heat will be enough there.

The negative influence of the sun

The time of exposure to infrared and ultraviolet waves must be strictly limited. In excess solar radiation:

may cause deterioration general condition the body (the so-called heat stroke due to overheating);
negatively affects the skin, causing permanent changes;
impairs vision;
provokes hormonal disruptions in the body;
can provoke the development of allergic reactions.

So that hours of lying on the beach during periods of maximum solar activity cause great damage to the body..

To get the necessary portion of light, a twenty-minute walk on a sunny day is enough.

The effect of the sun on the skin

Excessive solar radiation leads to serious skin problems. In the short term, you risk getting a burn or dermatitis. This is the smallest problem you can face when you get carried away with a tan on a hot day. If such a situation is repeated with enviable regularity, the radiation of the sun will be the impetus for the formation of malignant formations on the skin, melanoma.

In addition, UV exposure dries out the skin, making it thinner and more sensitive. And constant exposure to direct rays accelerates the aging process, provoking the appearance of early wrinkles.

In order to protect yourself from the negative effects of solar radiation, it is enough to follow simple safety measures:

AT summer time be sure to use sunscreen? Apply it to all exposed areas of the body, including the face, arms, legs and décolleté. The SPF badge on the packaging is the same UV protection. And its degree will depend on the number indicated near the abbreviation. For going to the store, cosmetics with an SPF 15 or SPF 20 level are suitable. If you plan to spend time on the beach, use special means with higher scores. For children's skin, a cream with a maximum protection of SPF 50 is suitable.
If you need to be outdoors for a long time at maximum intensity of sunlight, wear clothes made of light fabrics with long sleeves. Be sure to wear a wide-brimmed hat to hide the delicate skin of your face.
Control the duration of sunbathing. The recommended time is 15-20 minutes. If you are outside for a longer time, try to get some shade from the direct sunlight.

And remember that in the summer, solar radiation affects the skin at any time of the day, with the exception of night hours. You may not feel obvious heat from infrared waves, but ultraviolet does. high level activity, both in the morning and in the afternoon.

Negative effect on vision

The influence of sunlight on the visual apparatus is enormous. After all, thanks to light rays, we receive information about the world around us. Artificial lighting to some extent can become an alternative to natural light, but in conditions of reading and writing with a lamp, eye strain increases.

Speaking about the negative impact on a person and vision of sunlight, it means damage to the eyes during prolonged exposure to the sun without sunglasses.

Of the unpleasant sensations that you may encounter, one can single out cutting pains in the eyes, their redness, photophobia. The most serious lesion is a retinal burn.. It is also possible dry skin of the eyelids, the formation of small wrinkles.

Wear sunglasses. When buying, first of all, pay attention to the degree of protection. Image models often slightly obscure the light, but do not prevent the penetration of ultraviolet radiation. Therefore, it is recommended to put aside a bright frame and opt for quality lenses.
Make sure that direct rays do not fall on your face. Stay in the shade, wear a hat, cap or other headgear with a visor.
Don't look at the sun. If you do not experience discomfort, this does not indicate the safety of this undertaking. Even the winter sun has enough activity to provide vision problems.

Is there a safe time of year

The use of solar radiation as a health treatment is a common practice. That ultraviolet, that heat belongs to the category of strong irritants. And abuse of these benefits can earn serious problems.

Sunburn is the production of melanin. And to be more precise, the protective reaction of the skin to an irritant.

Is the radiation of the sun so dangerous at any time of the year? It is difficult to give a definite answer to this question. Everything will depend not so much on the season as on geographical location. So, in the middle latitudes, the activity of solar radiation increases by 25-35% in the summer. Therefore, the recommendations regarding staying outside on a clear day apply only to the hot season. In winter, residents of these regions are not threatened by ultraviolet radiation.

But the inhabitants of the equator face direct sunlight all year round. Therefore, the probability negative impact on the body is present both in summer and in winter. Inhabitants northern latitudes more fortunate in this respect. After all, with distance from the equator, the angle of incidence of the sun's rays on the earth changes, and with it the radiation activity. The length of the thermal wave increases, and at the same time the amount of heat decreases (energy loss). Hence the winter all year round, as the surface of the earth does not have enough heat to warm up.

Solar radiation is a friend of our body. But do not abuse this friendship. Otherwise, the consequences can be the most serious. Just enjoy the warmth without forgetting the precautions.

Many of us love to spend time in the sun, someone wants to soak up the warm rays, and someone is chasing a good tan. But is it useful for the body and how does it affect human health? Learn about the benefits and harms of sunlight.

The benefits of sunlight

If you approach this issue wisely, then tanning will positively affect your health. Sun exposure produces vitamin D, which has a beneficial effect on bones and teeth and promotes the absorption of calcium.

Ultraviolet has a beneficial effect on the human immune system. Experts have long proven that growth slows down in the sun. cancer cells. The body receives more oxygen during exposure to sunlight, which improves the functioning of the heart muscle and puts blood pressure in order.

Sun lovers are much less likely to get sick and cope better with stress. When exposed to sunlight, the body activates important processes such as respiration, circulation, metabolism.

Sun damage

If carried out in direct sunlight a large number of time increases the risk of skin cancer. Do not forget that prolonged exposure to the sun contributes to premature aging of the skin. To avoid such problems, use various oils and creams that will save skin covering from drying.

We must not forget about burns, the desire to tan quickly and strongly can bring you a lot of inconvenience and harm your health. Be aware of the risk of heatstroke, do not forget that in strong sunshine, your head should be covered.

What is the best time to sunbathe

If you come to rest in warmer climes and want to tan, remember the first 3-4 days you should refrain from long sunbathing. This will only harm you and your skin, and instead of a bronze tan, you can return home with burns.

If we talk about time, we must not forget that in the period from 12:00 to 16:00 the sun is most active and can harm your body. It is worth sunbathing before noon, preferably before 11 o'clock. The most favorable moment is the time from 16:00 to 19:00. During this period, the risk of getting burns is minimal. In addition, the evening sun rays will not affect your vision.

How to protect yourself from sun exposure

Before sunbathing, you should take care of protection. Be sure to purchase a hat with a visor or wide brim to avoid bumps and burns to your face.

Don't forget about sunscreen, which must be applied half an hour before going outside. During this time, the cream will be absorbed and a protective film will form. Apply the product every two hours.

Be mindful of your eyes, protect them with a large visor or sunglasses.

Be careful with your health, remember that in pursuit of a tan you can harm your skin. Enjoy the sun wisely. We wish you good luck and do not forget to press the buttons and
