1. The sunlight kills microbes. That's why it is important to put out in the
sun carpets, blankets and eiderdowns that cannot be washed regularly.
Exposure to the sun confers the skin a bright, healthy look and increased
elasticity.
A moderately tanned skin is more resistant to infections and sun burning
than an untanned one. Many skin diseases (dermatitis) can be controlled
and even cured through controlled exposure to the sun.
The sun rays are proven to strengthen the immune system.
2. Due to the sun our mood and morals improve. Sunlight helps in cases
of chronic or acute depression, by stimulating the synthesis of
endorphins (good-feeling hormones). That's why we get depressed in the
cold and dark days of the winter.
3. The sun is good against insomnia. Daytime exposure to sunlight
increases the melatonin production during the night. This hormone helps
regulate the sleep.
4. Under the action of the sunlight, the skin synthesizes vitamin D,
which makes possible calcium absorption in the intestine, helping the
organism grow strong bones. This way the sun prevents rachitism in
both children and adults and osteoporosis in elders.
5. As vitamin D and some related compounds impede the development of
some cancer cells, we can say the sun fights off this disease. Regular
and controlled exposure to the sun has a preventive effect against
cancer of colon, breast, leukemia and lymphomas.
6. Exposure to the sun strengthens the cardiovascular system. Blood
circulation is improved, the pulse, arterial pressure, moderately high
glycemia and cholesterol levels can be normalized.
7. Sun rays improve liver functioning, being effective in treating
jaundice.
8. They help the kidneys with a part of their job, as the sun waves favor
the elimination of waste products through the skin, when we sweat.
9. The sun also helps losing weight by increasing the metabolic rate
through the stimulation of the thyroid. It also eases symptoms of
premenstrual syndrome.
10. The sun rays also ease the healing of the swollen joints during peaks
of inflammation in cases of arthritis.
