IIt’s great to bathe in the sun again, and it has a great boost to the body. Ultraviolet rays (UV) in the sun helps our body produce vitamin D, which is necessary to strengthen bones and prevent diseases such as diabetes and certain cancers.
But in addition to vitamin D, the ultraviolet rays in the sun can also lower blood pressure and reduce the risk of heart attack and stroke by releasing nitric oxide in exposed skin, opening blood vessels, and increasing blood flow in the body. The blue light in the sun also strengthens the immune system by releasing hydrogen peroxide in the skin, activating key immune cells called T cells, and then they can move faster to any infection site.
In the days before antibiotics, sunlight has long been used to treat wounds and infections. Florence Nightingale believed that soldiers injured in the Crimean War should receive direct sunlight in the hospital. At the beginning of the 20th century, tuberculosis patients were treated in mountain clinics, and they were exposed to strong sunlight outdoors. Recently, it has been discovered that ultraviolet rays can kill tuberculosis bacteria, even more and more resistant strains.
Sunlight is an amazing medicine, of course, as long as it protects the skin from sunburn, it is fine.
