isIt’s great to be in the sun again, and also a big boost for the body. Ultraviolet (UV) rays from the sun help our bodies make vitamin D, which is necessary for strong bones and protection against diseases such as diabetes and certain cancers.
But apart from vitamin D, UV from the sun also lowers blood pressure and reduces the risk of heart attack and stroke by releasing nitric oxide into exposed skin, opening blood vessels, and increasing blood pressure. blood flow in the body. Blue light in the sun also stimulates the immune system by releasing hydrogen peroxide into the skin, energizing key immune cells called T cells, which can then move faster to any site of infection.
Sunlight has long been used to treat wounds and infections before antibiotics. Florence Nightingale argued that soldiers wounded in the Crimean War should receive direct sunlight in hospitals. And at the start of the 20th century, tuberculosis patients were treated in mountain clinics where they were exposed to strong sunlight outdoors. More recently, UV rays have been found to kill TB bacteria, even the drug-resistant strains that are becoming more prevalent.
Sunlight is an amazing drug, so long, of course, that the skin is protected from sunburn.
