We all expose our skin to the sun on a daily basis when we are outside our home, on the way to work, school and other of our daily endeavors. Exposure of the skin to the sun can have some benefits. Vitamin D is derived from sunlight. Vitamin D helps the human body absorb calcium and phosphate for healthy bone and teeth, and can prevent high blood pressure and osteoporosis. While being exposed to sunlight isn't that bad, prolong exposure can outweigh the benefits. Long-term exposure is harmful and poses potential dangers to the human body.

Unknowingly, people damage their skin from overexposure to the sun either through suntans, sun beds, sunlamps or tanning parlours. The sun emit ultraviolet (UV) rays which penetrate the skin and damage the skin cells. Long-term exposure damage the skin by altering the texture of the skin and weakens its elasticity, thus leading to sunburn (erythema), skin spots, wrinkles, blistering, peeling, sagging and more worse is skin cancer. Basal cell carcinomas, squamous cell carcinomas and melanoma are different forms of skin cancer that can develop as a result of skin damage caused by UV radiation from the sun.
Cataracts is the leading cause of blindness in the world. Cataracts are cloudy areas inside the eye's lens. Cataracts develops when proteins in an eye's lens unravel, tangle and accumulate pigments that cloud the lens. Although there are others factors that can cause cataracts, long-term exposure to bright sunlight increases the risk of developing cataracts.
Research studies have shown that overexposure of the skin to sunlight can suppress the immune system. Have you ever thought of it why you should not be under the sun when sick? The skin is the body's first line of defense. If damaged, it may reduce the body's ability to fight and defend itself against some infectious diseases. In other words, long-term exposure of the skin to the sun cause damage to the immune function of the skin cells and can affect other parts of a person's immune system. This could lead to perturbation of the immune cells in the blood stream. Sunlight exposure have been known to increase the risk of bacterial, fungal, parasitic, or viral infections. There have been reported cases of people with herpes simplex who experience recurrence of cold sores in the lips after being exposed to the sun.
Undoubtedly, we need to protect ourselves from the damaging effects of UV radiation if we want to safeguard our health. Without good health and sound body, it will be difficult to achieve so many things in life. Our health is our live! Protecting yourself from the sun harmful rays will make your skin look younger.
Note: Do not be deceived thinking that having dark skin makes you less susceptible to ultraviolet ray. The sun can damage any skin type.
