Tannig is healthy, but in moderation

Sun is vital for humans, not just because it lights and heats the earth, making vegetables grow, but also because of its benefits on human's health.

Sun makes people happier, enhancing our mood and stimulating our energy.

This is easy to demonstrate: a trip in sunny countries makes you understand how the sun can influence the attitude of people.

They are more relaxed, warm-hearted and willing to share more time, meals and fun outdoors with families and friends.

Studies prove that the brain produces more serotonin on sunny days, which acts as a natural antidepressant.

Between 4 and 6 percent of the U.S. population suffers from seasonal affective disorder, according to the Cleveland Clinic in Ohio, SAD, seasonal affective disorder, is a condition that typically generates depression and sadness during autumn and winter and then goes away in the sunnier months.

Sunlight also boosts also your appearance, making us look healthier with a fresh glow.

An online survey conducted in the U.S. by the American Academy of Dermatology found that 58 percent of respondents aged 18 to 29 believe people look more attractive with a tan, and 71 percent agreed with the statement: "Sun exposure is good for your health."

Sun is also the best source for Vitamin D, which is crucial for our immune system, protecting us from cardiovascular diseases, cancer and infections.

The so-called "sunshine vitamin" is also an excellent supplement for our bones, and a deficiency of it has been associated with falls, low bone mineral density, and osteomalacia (called rickets when it occurs in children).

Studies, from Atlas of Cancer Mortality Rates for the United States, 1950-94, (cancer.gov/atlasplus/type.html), show that about 50,000-63,000 annual cancer deaths in the U.S. (10% of all cancer deaths) could be prevented if all Americans had sufficient vitamin D. In the UK, the preventable cancer deaths with sufficient vitamin D may be as high as 20% since oral intake is low and vitamin D produced from solar UVB is much lower than in the U.S.

According to studies, getting up to ten minutes of direct sun exposure each day helps the body produce vitamin D.

Vitamin D is not actually an essential dietary vitamin in the strict sense, because it is synthesized from sunlight. However, it is possible to increase its intake with a diet in order to maintain an adequate serum levels (from a vitamin D3 blood test)

Dietary sources of vitamin D include: fatty fish, mushrooms, eggs and beef liver.

Scientists are divided between about the sun's benefits against cancer, multiple sclerosis, and osteoporotic hip fracture that likely could have been prevented with sufficient vitamin D, and the number of cases and deaths from skin cancer, eye injuries and cataracts that likely have been prevented by avoiding excess UV irradiance.

It is well known that over exposure to the sun causes irreversible skin damages: it can lead to wrinkles, prematurely aging skin and in the worst cases even a cancer diagnosis  . Melanoma is the most deadly form of skin cancer.

According to The U.S. National Cancer Institute, Melanoma is the most common cancer for Americans aged 25 to 29, and the second most common cancer among those aged 15 to 29. 

Using tanning beds increases the risk of melanoma, especially in women aged 45 or younger.


An excessive exposure to the sun's rays can also dehydrate the body, giving a sense of fatigue and dizziness. Other harmful effects are sunburns and heat-strokes.

The byword “too much of anything is bad” is always true.

The key is to sunbathe gradually, with a good cream with high protective factor, and always use common sense.
