The sun is the source of life on the planet. Its rays provide the necessary light and warmth. At the same time, ultraviolet radiation from the Sun is destructive to all living things. To find a compromise between the beneficial and harmful properties of the Sun, meteorologists calculate the ultraviolet radiation index, which characterizes the degree of its danger.

What kind of UV radiation from the sun is there?

Ultraviolet radiation from the Sun has a wide range and is divided into three regions, two of which reach the Earth.

  • UVA. Long-wave radiation range
    315–400 nm

    The rays pass almost freely through all atmospheric “barriers” and reach the Earth.

  • UV-B. Medium wave range radiation
    280–315 nm

    The rays are 90% absorbed by the ozone layer, carbon dioxide and water vapor.

  • UV-C. Shortwave range radiation
    100–280 nm

    The most dangerous area. They are completely absorbed by stratospheric ozone without reaching the Earth.

The more ozone, clouds and aerosols in the atmosphere, the less the harmful effects of the Sun. However, these life-saving factors have a high natural variability. The annual maximum of stratospheric ozone occurs in spring, and the minimum in autumn. Cloudiness is one of the most variable characteristics of weather. The carbon dioxide content also changes all the time.

At what UV index values ​​is there a danger?

The UV index provides an estimate of the amount of UV radiation from the Sun at the Earth's surface. UV index values ​​range from a safe 0 to an extreme 11+.

  • 0–2 Low
  • 3–5 Moderate
  • 6–7 High
  • 8–10 Very high
  • 11+ Extreme

In mid-latitudes, the UV index approaches unsafe values ​​(6–7) only when maximum height The sun is above the horizon (occurs in late June - early July). At the equator, the UV index reaches 9...11+ points throughout the year.

What are the benefits of the sun?

In small doses, UV radiation from the Sun is simply necessary. The sun's rays synthesize melanin, serotonin, and vitamin D, which are necessary for our health, and prevent rickets.

Melanin creates a kind of protective barrier for skin cells from the harmful effects of the Sun. Because of it, our skin darkens and becomes more elastic.

The hormone of happiness serotonin affects our well-being: it improves mood and increases overall vitality.

Vitamin D strengthens the immune system, stabilizes blood pressure and performs anti-rickets functions.

Why is the sun dangerous?

When sunbathing, it is important to understand that the line between the beneficial and harmful Sun is very thin. Excessive tanning always borders on a burn. Ultraviolet radiation damages DNA in skin cells.

The body's defense system cannot cope with such aggressive influence. It lowers immunity, damages the retina, causes skin aging and can lead to cancer.

Ultraviolet light destroys the DNA chain

How the Sun affects people

Sensitivity to UV radiation depends on skin type. People of the European race are the most sensitive to the Sun - for them, protection is required already at index 3, and 6 is considered dangerous.

At the same time, for Indonesians and African Americans this threshold is 6 and 8, respectively.

Who is most influenced by the Sun?

    People with fair hair
    skin tone

    People with many moles

    Residents of mid-latitudes during a holiday in the south

    Winter lovers
    fishing

    Skiers and climbers

    People having family history skin cancer

In what weather is the sun more dangerous?

It is a common misconception that the sun is dangerous only in hot and clear weather. You can also get sunburned in cool, cloudy weather.

Cloudiness, no matter how dense it may be, does not reduce the amount of ultraviolet radiation to zero. In mid-latitudes, cloudiness significantly reduces the risk of getting sunburned, which cannot be said about traditional places beach holiday. For example, in the tropics, if in sunny weather you can get sunburned in 30 minutes, then in cloudy weather - in a couple of hours.

How to protect yourself from the sun

To protect yourself from harmful rays, follow simple rules:

    Spend less time in the sun during midday hours

    Wear light-colored clothing, including wide-brimmed hats

    Use protective creams

    Wear sunglasses

    Stay in the shade more on the beach

Which sunscreen to choose

Sunscreen varies in degree of sun protection and is labeled from 2 to 50+. The numbers indicate the proportion of solar radiation that overcomes the protection of the cream and reaches the skin.

For example, when applying a cream labeled 15, only 1/15 (or 7 %) of the ultraviolet rays will penetrate the protective film. In the case of cream 50, only 1/50, or 2 %, affects the skin.

Sunscreen creates a reflective layer on the body. However, it is important to understand that no cream can reflect 100% of ultraviolet radiation.

For everyday use, when the time spent under the Sun does not exceed half an hour, a cream with protection 15 is quite suitable. For tanning on the beach, it is better to take 30 or higher. However, for fair-skinned people it is recommended to use a cream labeled 50+.

How to Apply Sunscreen

The cream should be applied evenly to all exposed skin, including the face, ears and neck. If you plan to sunbathe for a long time, then the cream should be applied twice: 30 minutes before going out and, additionally, before going to the beach.

Please check the cream instructions for the required volume for application.

How to Apply Sunscreen When Swimming

Sunscreen should be applied every time after swimming. Water washes off the protective film and, reflecting Sun rays, increases the dose of ultraviolet radiation received. Thus, when swimming, the risk of sunburn increases. However, due to the cooling effect, you may not feel the burn.

Excessive sweating and wiping with a towel are also reasons to re-protect the skin.

It should be remembered that on the beach, even under an umbrella, the shade does not provide complete protection. Sand, water and even grass reflect up to 20% of ultraviolet rays, increasing their impact on the skin.

How to protect your eyes

Sunlight reflected from water, snow or sand can cause painful burns to the retina. To protect your eyes, wear sunglasses with a UV filter.

Danger for skiers and climbers

In the mountains, the atmospheric “filter” is thinner. For every 100 meters of height, the UV index increases by 5 %.

Snow reflects up to 85 % of ultraviolet rays. In addition, up to 80 % of the ultraviolet reflected by the snow cover is reflected again by clouds.

Thus, in the mountains the Sun is most dangerous. It is necessary to protect your face, lower chin and ears even in cloudy weather.

How to deal with sunburn if you get sunburned

    Use a damp sponge to moisten the burn.

    Apply anti-burn cream to the burned areas

    If your temperature rises, consult your doctor; you may be advised to take an antipyretic

    If the burn is severe (the skin swells and blisters greatly), seek medical attention. medical care

For those who spent the whole summer in Moscow and worked non-stop, we recommend going to Dubai. Now there is the summer that every resident of the metropolis dreams of, who spent all the summer months wearing a coat and watching the rain outside the window. Throughout September, the temperature in Dubai varies from +34 to + 36, and there are no cloudy or partly cloudy days on the calendar!

Dubai is also attractive from a visa point of view. Firstly,

From February 1, visas to the UAE became free, which means the trip became cheaper by another $75.

Secondly, you no longer need to apply for a visa in advance, so you can go to Dubai even this evening, you just need to buy a ticket.

In addition to skyscrapers, shopping, luxurious beaches Persian Gulf and water in which you splash like in warm milk (or in soup - but then it’s already unpleasant), in Dubai you can immerse yourself in the world of contemporary art or pay attention to Muslim fashion - a lot of interesting things have appeared here over the past few years.

Montenegro


Varvara Gertier/RIA Novosti

You can and should go to Montenegro in the fall - when the temperature does not go beyond +35, touching wilting begins to appear in nature, the danger of encountering a forest fire disappears, the beaches become freer, and figs and grapes appear in the markets (in July there are also figs , but you didn’t make it there in July?). The absence of oppressive heat means that you won’t lie helplessly in a hammock all day long and will be able to travel around the country, which, in addition to the beaches of Budva and the sunsets of Kotor, has a lot to offer.

For example, Cetinje is the cultural capital of Montenegro, to which no one goes of their own free will in the summer, because they really don’t want to move away from the sea. Here you can go to National Museum Montenegro and the Cetinje Monastery, see the oldest libraries in the country, find out what students of the Faculty of Fine Arts and the Faculty of Drama, as well as the Music Academy of the University of Montenegro look like, walk through parks in English and French style.

In general, in Cetinje in the fall you can stop feeling like a sweaty vegetable and learn something about the culture and history of Montenegro,

because this is not just a resort, but a city where Prince Ivan I Cernoevich founded his residence in 1482, and in 1838 the first secular residence of Montenegrin rulers was built by the beloved fighter for the independence of the country, Peter II Njegos.

Agadir, Morocco


Amr Dalsh/Reuters

You do not need a visa to travel to Morocco. You can swim and sunbathe in Agadir throughout September; the air temperature throughout the month will not drop below + 27. However, in Agadir you can not only sunbathe.

For example, you can visit the Domaine Villate Limoune wild animal ranch, where porcupines, kangaroos, camels, and peacocks live. Or head to the city's main market, Souk el Had, where you can buy everything from babushka slippers, pottery and stoles to oils, olives, dates and oranges.

Nice, France


Eric Gaillard/Reuters

If the heat makes you dizzy and the word "tan" means " premature aging", - go to the Cote d'Azur in September-October. The sun is no longer burning here, but the weather is still good - the temperature ranges from + 22 to + 25. You can still swim in this weather, although there is already something to do in Nice. For example, you can go to the Museum fine arts or take a walk in the Botanical Garden, where more than 3.5 thousand plants are presented. For lovers of walking, we recommend exploring the old town (here, by the way, you can also visit the opera), and for fans of archeology, stop by the Semje quarter and see

an arena for gladiator fights, an antique bath complex and the remains of ancient buildings.

A holiday in Nice is also suitable for shopaholics - the range of boutiques on Rue de France is in no way inferior to the world's fashion capitals.

The biggest advantage of a holiday in Nice is the opportunity to make your holiday even more eventful by going to nearby Cannes and Monaco. The cities are only 30 minutes away from each other. There will be enough impressions from what you see for your entire vacation: casinos, premium car showrooms, yachts at arm's length, the red carpet of the Cannes Film Festival and many Michelin-starred restaurants.

We recommend that nature lovers visit the Arboretum; here you can experience summer to the fullest. Or go see the waterfalls. There are Agur waterfalls to choose from - the most popular among tourists, Azhek waterfall - these are the two most beautiful waterfalls, and the highest waterfall - Orekhovsky (28 m). A one-day trip to Abkhazia (travel time will take about 3 hours) or to the mountains can diversify your trip - in summer Krasnaya Polyana looks even better than during the ski season.

Today, with snow slowly falling outside the window, we want to tell you about those places where “eternal May” reigns. Do you think this is a poetic exaggeration? But no.

There are many different and amazing places on our planet. Among them there are those where beautiful sunny weather reigns all year round. And this is reality!
