What are the benefits of sunlight to the body


    What are the benefits of sunlight to the body

  • 1 Protects against cancer

    According to some researchers, raising the serum levels of vitamin D was found to be ideal for cancer prevention, which means 600,000 cases of breast and colorectal cancer could be prevented each year with sufficient exposure to sunlight. 

  • 2 Helps to get a better night sleep

    Exposing the body to the needed amount of sunlight can help the body to maintain a normal circadian rhythm. Natural daylight helps the body's biological clock to restart its active daytime phase. See also: how to have a good night sleep.

  • 3 Improves the mood

    Seasonal depression and mood variation have been linked to sunlight exposure. Naturally, regular exposure to sunlight increases serotonin levels, affecting the mood. Researches show that serotonin level in the brain is lowest during winter in many countries due to lack of sunlight. 

  • 4 Lowers blood pressure

    When exposed to ultraviolet rays, nitric oxide is released. It's a compound that lowers blood pressure.

  • 5 Protects against melanoma

    Outdoor exposure of the skin to ultraviolet radiation of short wavelegnths(UVB) can decrease the risk of melanoma (a tumour of melanin-forming cells). However, indoor exposure can result in vitamin D deficiency and increase the risk of melanoma, as indoor UV breaks down vitamin D3 formed.

  • 6 Provides the body with vitamin D

    A healthy supply of vitamin D promotes bone growth and prevents breast and colon cancer, inflammation, multiple sclerosis, seasonal disorders, and depression.

  • 7 Heals some skin disorders

    Sunlight can heal some skin problems as psoriasis, acne, eczema and fungal infections of the skin.

  • 8 Good for teeth

    A dental study done in Scotland found that the risk of developing cavities in children was greater in areas with less than average sunshine.

  • 9 Boosts fertility

    The sun reduces melatonin levels, which is a hormone that suppresses fertility. A study in Turkey found that women who get less than an hour of sunlight a week reach menopause seven to nine years earlier. Sunlight also boosts testosterone levels in men.

  • 10 Contributes to bone health in older adults

    Vitamin D stimulates the absorption of bone-strengthening calcium. Researches show that higher blood levels of vitamin D3 are associated with a lower rate of many types of fractures, while lower blood levels of vitamin D3 are associated with a higher rate of fractures. See: how to strengthen bones.

  • 11 Lowers the risk of multiple sclerosis

    Observations suggest that early sunlight exposure in the first two decades of life influences the risk of developing MS, as well as maternal levels of vitamin D during the third trimester of pregnancy.

  • 12 Beneficial for Alzheimer's patients

    Clinical research has shown that exposure to full-spectrum light throughout the day coupled with darkness at night can help improve some aspects of Alzheimer’s disease, such as reducing agitation and decreasing nighttime activity in these patients. 

  • 13 Good for women

    About one in five women of childbearing age suffer from polycystic ovary disease which causes abnormal periods, unwanted body hair and infertility. Science confirms that vitamin D and calcium are the best cure. Also, women with premenstrual syndrome are likely to be deficient in vitamin D.

  • 14 Boosts the immune system

    Sunlight helps in producing more white blood cells (Lymphocytes), which defend the body and help it to fight many infections. See also: the benefits of vitamin C.

  • 15 Relieves aches and pains

    The sun warms the muscles and eases stiffness. This reduces inflammation in the body which decreases pain, such as arthritis. See also: how to relieve back pain fast.

  • 16 Sunlight exposure should be in moderation

    Sunlight has many health benefits. However, exposure should be in moderation. Factors such as skin pigmentation, time of day, and how much skin is exposed, all determine the healthiest dosage of sunshine for the body.
