Are you all aware of the fact that too much exposure to UV radiation from the sun can cause skin cancer? Yes, but did you know that enough sunlight can also have many health benefits? Sunlight is known of its ability to boost the body’s vitamin D supply. Vitamin D, sometimes called the “sunshine vitamin”, is produced in the skin in response to sunlight. The most important functions of Vitamin D include regulating the absorption of calcium and phosphorus and facilitating normal immune system function. Getting a sufficient amount of vitamin D is important for the normal growth and development of bones and teeth, as well as improved resistance against certain diseases.

The right amount of exposure to sunlight can also have lots of mood-lifting benefits. Exposure to sunlight is thought to increase the brain’s release of a hormone called serotonin. Serotonin is associated with boosting mood and helping a person feel calm and focused. Without enough sun exposure, serotonin levels can drop. Low levels of serotonin are associated with a higher risk of major depression with seasonal patterns. This form of depression is formerly known as a seasonal affective disorder or SAD and is triggered by the changing seasons.

Although excess sunlight can contribute to skin cancers, a moderate amount of sunlight has preventive benefits when it comes to several forms of cancer including colon, breast, and prostate cancer and non-Hodgkin lymphoma. Researchers have also noted a link between exposure to the sun and lower blood pressure levels, with reduced death rates from cardiovascular issues. Increased sun exposure, based on latitude, has been also associated with decreased risk of developing several different types of diseases including type 1 diabetes, multiple sclerosis, and other diseases.

The sunlight exposure presented many health benefits but sun emits ultraviolet (UV) radiation. The ultraviolet (UV) radiation can penetrate the skin and damage cell DNA which can lead to skin cancer. But how much is enough? There is no exact measurement for how long you should stay outside to reap the benefits of sunlight. But defining an excess amount of sun exposure depends on your skin type, age, health history, diet, and where you live. According to World Health Organization (WHO), getting anywhere from 5 to 15 minutes of sunlight on your arms, hands, and face 2-3 times a week is enough to enjoy the vitamin D-boosting benefits of the sun. But wearing sunscreen or clothing over your skin won’t result in vitamin D production. To protect your skin from skin cancer, you can apply sunscreen with a sun protection factor (SPF) of at least 15. Wear your protective hat or umbrella under the sun!
