The sun gives us light, heat, and ultraviolet radiation. All three types of radiation have a major influence on the human organism. This impact can be favorable and unfavorable. It is desirable to use favorable ones and to protect themselves from the adverse effects of solar radiation.
The sun is a huge source of energy. The temperature on its surface reaches up to 6000 ° C, and it is assumed that the temperature in the interior reaches up to 15.6 million degrees Celsius.
Fortunately, the Earth is about 150 million kilometers from the Sun. Once in the sun, it takes about 8 minutes and 20 seconds to reach Earth. Just in time.
Natural sunlight is one of the basic stimulating factors of the crust of the big brain and thus of the whole organism. The light allows for vision, gives a positive mood, better motivation to work with fewer errors, and greater work performance. Hot radiation positively affects rheumatic chronic illnesses. Vitamin D is produced by ultraviolet radiation, which is essential for proper bone development, prevents rhinitis and osteoporosis. Ultraviolet rays also have bactericidal activity, accelerate wound epithelialization, affect the blood vessels, increase antibodies, reduce the risk of colds. In general, sunlight raises the level of the general health of the organism.
The appropriate amount of sunlight gives the skin a healthy glow and makes it smooth and elastic. Medium darkened skin is more resistant than unwashed skin to infections and sunburn.
In combination with active exercise, sunlight is an important element in the treatment of acute and chronic depression. Remember, if you have been depressed during the winter cold and gloomy months, try to use every possibility of exposure to sun rays.
The action of sunlight on the skin helps the body in the production of vitamin D. This vitamin allows us to put calcium from the bowel in the blood and use it to build
healthy bones. It prevents the onset of rachitis in children and reduces the possibility of osteoporosis in adults.
The sun’s light also helps:
- strengthening of the immune system;
- pain relief in swollen, arthritic joints; Facilitating certain symptoms of PMS;
- lowering blood cholesterol levels.
However, increased sunlight can cause health problems associated with high temperatures or enhanced ultraviolet radiation.
The effect of ultraviolet (UV) sun rays amplifies large water surfaces, snow, and cloudy clouds due to reflecting up to 75% but also the damaged ozone layer that otherwise serves as a UV filter.
UV radiation. It is expressed on a scale of 0 to 10+. The index is calculated taking into account the level of the ozone layer, the number of clouds, and the geographical position. Radiations with an index of over 6 give a high risk of damage to human health, and then strong enforcement measures should be taken.
Ultraviolet rays can seriously endanger human health. Their locally detrimental effect is redness, islet, itching, pain, and peeling of the skin, as well as redness and eye pain. The general effect is expressed by fatigue, fatigue, squinting, falling blood pressure, discomfort and vomiting.
Any exposure to UVA or UVB light can alter or damage the skin. Long-term exposure to natural sunlight or artificial salons to obtain overcrowding can cause long-term damage to the skin. Quite simply, there is no “safe overcrowding”.
The skin damaged by the sun represents a weak obstruction against infection and if the infection develops, recovery can be slowed down.
We should be aware of the consequences of burns caused by excessive exposure to the sun. Any such burns destroy the healthy, living tissue of the skin. Often burns cause irreparable damage.
Multiple skin scarring, even repeatedly deep tanning of the skin, gradually destroys its elasticity and the salivary glands.
Sunburn is caused by excessive exposure to ultraviolet B (UVB) air. Depending on the type of skin pigment that a person has and the amount of exposure to the sun, the skin turns red, swollen, and becomes painful for an hour to a day after exposure to the sun. Later, bubbles can be created and the skin can be peeled. Some people burned by the sun get a fever, trembling, and weakness, and those with very severe sunburn can even fall into shock, get low blood pressure, fainting, and strong weakness.
Due to the direct effect of the sun on the head can occur sunburn, or the islet of the brain when headaches, cramps, high temperature occur. It is necessary to refresh and emergency medical intervention.
Prevention of burns from the sun(sunburn)
The best, and most intelligible, way to prevent sun damage is to move away from strong, direct sunlight. Clothes and usually window glass stops (selectively filtering) practically all the dams that damage it. Water is not a good filter for UV, UVA, and UVB, rays can penetrate up to 30 centimeters through clean water, which can be detected by divers with underwater masks and barefoot walkers. Neither clouds nor fog are good filters, a person can bake sun on a cloudy and foggy day. Snow, water, and sand reflect sunlight, multiplying the amount of UV radiation that reaches the skin.
Before exposure to strong direct sunlight, persons should be protected with cream, some grease, or cream-containing chemicals that protect the skin by filtering UVA and UVB air. Many protective creams are either waterproof or water-resistant. One common effective type of protective cream contains para-aminobenzoic acid (PABA). By swim or sweating, PABA will soon be flushed, because it is firmly attached to the skin for 30-45 minutes. Sometimes, protective creams that contain PABA irritate the skin, and in some people can cause allergic reactions.
Other protective creams contain physical barriers such as zinc oxide or titanium dioxide, and thick, white fats prevent the arrival of sun rays on the skin and can be applied to sensitive areas such as the nose or lips. People who have an important appearance can paint these fats with cosmetic products to make them similar to their skin color.
Guidelines for safe, healthy exposure to sunlight
The optimum time for most people is about 30 minutes of sunbathing as much body surface as possible per day. Make sure you never burn in the sun.
Moderately, gradually tanning the skin acts like protective goggles. But you must know your own tolerance of exposure to sunlight.
We know that the sun can act beneficially, but also deadly, it can be a kiss of life or a kiss of death, depending on how much we expose it.
Wear protective clothing and glasses and regularly apply a protective cream.
A few minutes of sunbathing your face and your hands will produce enough vitamin D every day. Lift up the shutters every morning, stretch the curtains and open the windows with sun rays. You will also improve your health and mood.

One hour in daylight can lift your ghost, fill you with positive energy, improve your dream and fertility, and ease the pain before (PMS) and during the cycle.
Differences in the number of sunny hours during seasons can seriously affect the mental health of people. Thus, there are people suffering from depressive disorders caused by changing seasons and this type of depression is successfully treated with light therapy.
People who get more sunlight are less likely to suffer from breast, colon, and prostate cancer.
