The city is located in the southern part of Arizona, in a picturesque oasis of the Santa Cruz River valley in semi-desert places. Located 188 km southeast of Phoenix. The city is constantly experiencing an acute shortage of water resources.

For a long time, the only inhabitants of these places were the Navajo Indian tribes. And the first European military fort appeared here in 1768. It was founded by the Spaniards, after which the city was under the control of the Spanish crown for a long time, and then came under the jurisdiction of independent neighboring Mexico.

Numerous tourists in this city are attracted by ancient buildings of Spanish architecture. There are many museums here. This is, first of all, the Arizona State Museum and the famous art museum, which exhibits items of Latin American art. As well as the Museum of the Arizona Historical Society.

The sun is the source of life on the planet. Its rays give the necessary light and warmth. At the same time, ultraviolet radiation from the Sun is detrimental 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 UV radiation from the sun is

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

• UV-A. Longwave radiation range
  315–400 nm

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

• UVB. Medium wave radiation range
  280–315 nm

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

• UVC. Shortwave radiation range
  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 effect of the Sun. However, these saving factors have a high natural variability. The annual maximum of stratospheric ozone occurs in spring, and the minimum - in autumn. Cloud cover is one of the most variable weather characteristics. The content of carbon dioxide 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

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

What is the benefit of the sun

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.

Happiness hormone 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 beneficial and harmful Sun is very thin. Excessive sunburn always borders on a burn. UV radiation damages DNA in skin cells.

The body's defense system cannot cope with such an aggressive impact. This lowers the immune system, damages the retina, causes skin aging and can lead to cancer.

Ultraviolet destroys the DNA chain

How does the sun affect people?

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

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

Who is affected the most by the Sun?

people with light
skin tone

People with many moles

Residents of the middle latitudes while relaxing in the south

winter lovers
fishing

Skiers and climbers

People with a family history of skin cancer

In what weather is the sun most dangerous

The fact that the Sun is dangerous only in hot and clear weather is a common misconception. You can also get burned in cool cloudy weather.

Cloudiness, no matter how dense it may be, does not at all reduce the amount of ultraviolet 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 sunny weather you can get burned in 30 minutes, then in the cloud - in a couple of hours.

How to protect yourself from the sun

To protect yourself from harmful rays, follow these simple rules:

Get less exposure to the Sun during the 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 differs in the degree of protection from the Sun and is marked 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 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 is capable of reflecting 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 and above. 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 refer to the cream instructions for how much to apply.

How to apply sunscreen while swimming

Sunscreen should be applied every time after bathing. 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 burning increases. However, due to the cooling effect, you may not feel the burn.

Excessive sweating and rubbing with a towel is also a reason to re-protect the skin.

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

How to protect your eyes

Sunlight reflecting off water, snow, or sand can cause painful retinal burns. Use sunglasses with an ultraviolet filter to protect your eyes.

Danger for 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, in the mountains, the Sun is most dangerous. Protecting the face, lower part of the chin and ears is necessary even in cloudy weather.

How to deal with sunburn if you are burned

Treat the body with a damp sponge to wet the burn

Lubricate the burnt areas with anti-burn cream

If the temperature rises, consult a doctor, you may be advised to take an antipyretic

If the burn is severe (skin is very swollen and blisters), seek medical attention.
