The sun is the source of life on the planet. Its rays provide the necessary light and warmth. At the same time, the ultraviolet radiation of the Sun is detrimental to all living things. To find a compromise between the beneficial and harmful properties of the sun, meteorologists calculate the index of ultraviolet radiation, which characterizes the degree of its danger.
What UV radiation from the Sun is
Ultraviolet radiation from the Sun has a wide range and is subdivided into three regions, two of which reach the Earth.
-
UV-A. Long-wavelength radiation range
315-400 nmThe rays pass almost freely through all atmospheric "barriers" and reach the Earth.
-
UV-B. Medium-wave range radiation
280-315 nmThe rays are 90% absorbed by the ozone layer, carbon dioxide and water vapor.
-
UV-C. Shortwave range radiation
100-280 nmThe most dangerous area. They are completely absorbed by stratospheric ozone before reaching the Earth.
The more ozone, clouds and aerosols in the atmosphere, the less the harmful effects of the Sun. However, these saving factors have a high natural variability. The annual maximum of stratospheric ozone is in the spring, and the minimum is in the fall. Cloudiness is one of the most variable characteristics of weather. The carbon dioxide content also changes all the time.
At what values of the UV index is there a danger
The UV Index gives an estimate of the amount of UV radiation from the Sun on the Earth's surface. UV Index values range from safe 0 to extreme 11+.
- 0 - 2 Low
- 3 - 5 Moderate
- 6 - 7 High
- 8 - 10 Very high
- 11+ Extreme
At mid-latitudes, the UV index approaches unsafe values (6–7) only at the maximum height of the Sun above the horizon (occurs in late June - early July). At the equator, the UV index reaches 9 ... 11+ points throughout the year.
Why the sun is useful
In small doses, UV radiation from the Sun is essential. The sun's rays synthesize melanin, serotonin, vitamin D 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 has antirachitic functions.
Why the sun is dangerous
Taking sun baths, it is important to understand that the line between 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 an aggressive effect. It lowers immunity, damages the retina of the eyes, causes aging of the skin, and can lead to cancer.
Ultraviolet light destroys the DNA chain
How the sun affects people
Susceptibility to UV radiation depends on skin type. People of the European race are 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 affected by the Sun
People with light
skin tone
People with many moles
Residents of the middle latitudes while vacationing in the south
Winter lovers
fishing
Alpine skiers and climbers
People with a family history of 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 get burnt even in cool cloudy weather.
Cloudiness, no matter how dense it may be, does not at all reduce the amount of ultraviolet radiation to zero. In mid-latitudes, cloudiness significantly reduces the risk of sunburn, 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 on a cloudy day - in a couple of hours.
How to protect yourself from the sun
To protect against harmful rays, observe simple rules:
Stay less in the Sun at midday hours
Wear light-colored clothing, including wide-brimmed hats
Use protective creams
Wear sunglasses
You are more in the shade on the beach
Which sunscreen to choose
Sunscreen varies in 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 UV rays will penetrate the protective film. In the case of 50 cream - only 1/50, or 2%, affect the skin.
Sunscreen creates a reflective layer on the body. At the same time, it is important to understand that no cream is capable of reflecting 100% of ultraviolet radiation.
For everyday use, when the time spent in the sun does not exceed half an hour, a cream with protection 15 is quite suitable. For sunbathing on the beach, it is better to take 30 or more. However, for light-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 long enough, then the cream should be applied twice: 30 minutes before going out and, additionally, before going to the beach.
Specify the required amount for application in the instructions of the cream.
How to apply sunscreen when swimming
Sunscreen should be applied every time you bathe. Water washes away the protective film and, reflecting the sun's rays, increases the dose of ultraviolet radiation received. Thus, when bathing, the risk of sunburn increases. However, due to the cooling effect, you may not feel the burn.
Excessive sweating and towel drying is also a reason to re-protect your skin.
It should be remembered that on the beach, even under an umbrella, the shade does not provide adequate protection. Sand, water and even grass reflect up to 20% of UV rays, increasing their effect on the skin.
How to protect your eyes
Sunlight bouncing off water, snow or sand can cause painful retinal burns. Use UV-filtered sunglasses to protect your eyes.
Danger to skiers and climbers
In the mountains, the atmospheric "filter" is thinner. For every 100 meters of altitude, the UV index increases by 5%.
Snow reflects up to 85% of UV rays. In addition, up to 80% of the ultraviolet reflected by the snow cover is again reflected by the clouds.
Thus, the Sun is most dangerous in the mountains. Protecting your face, lower chin and ears is essential even in cloudy weather.
How to deal with sunburn if you are burned
Sponge your body with a damp sponge to dampen the burn
Apply an anti-burn cream to the burned areas.
If the temperature rises, consult a doctor, you may be advised to take an antipyretic
If the burn is severe (the skin is very swollen and blistering), seek medical attention

Cape Coral is a city in the Lee region of Florida, USA, with a population of about 170 thousand people and an area of approximately 298 sq. km, the second largest after Jacksonville in all of Florida.
An original feature is the numerous artificial canals laid in the 50s of the 20th century. Two brothers from the American northeast came here and bought a peninsula, which they called Cape Coral. The brothers wanted to build the city of their dreams here. Since the soil in these places was mostly swampy, the problem was solved by the fact that canals were laid, and houses were built on the hills and sold to those who wish. Thus, a city emerged, where most of the houses stand on the canal leading to the Gulf of Mexico.
Since its inception, the city has been known as a sleepy commune where little happens. The reason for this was the pensioners who made up the majority of the population, who came here to spend the rest of their days in a pleasant and warm climate. However, big changes have come since 1990, when many young families moved to the city, who were also attracted by the warm weather, the close sea and the opportunities for a variety of recreation, mainly sport fishing and aquatic species sports.
Thanks to this, Cape Coral began to attract more and more young people. Today the city can offer a variety of shops, restaurants and nightclubs, until recently located only in Fort Myers, a city that lies in the immediate vicinity and is separated by the Kalosakhachi River. Cape Coral and Fort Myers are connected by several bridges.
Cape Coral is very popular mainly with German tourists who have bought a lot of real estate here. But since they manage to get across the ocean twice a year, the rest of the time they offer their properties for rent to others. German tourists through travel agencies. Some of the owners offer to rent a house in a complex with a boat rental, moored right behind the house. international Airport at Fort Myers provides direct message with Dusseldorf 3 times a week.
Cape Coral also has its own small beach with a restaurant and panoramic views, from where many admire the sunset.
