Sunbathing helps to improve the blood circulation in the body and eliminates toxins from the body. It is also necessary for the absorption of calcium by the bones. Research also suggests that UVB rays promote the synthesis of vitamin D3 in the human body, which is crucial to increase in blood pressure. Even babies are exposed to sunlight for strong bones and teeth. Sunrays have unique healing power and are even beneficial to treat skin disorders, such as psoriasis, acne, and eczema. The light of the sun penetrates deep into the skin to cleanse the blood vessels.
