In limited quantities, ultraviolet rays are not only beneficial but also necessary for maintaining proper health. The Vitamin D from the sun s rays can help cure several diseases such as eczema, jaundice and psoriasis. If adequate amounts of sun rays are not received by the body, bone growth gets hampered that can result in osteoporosis and other bone weakness issues. However, if it is received in abundance, its effects can be profusely detrimental to the immune system, eyes and the skin.

Since skin tanning and sun-bathing have become increasingly popular among the mass, it is necessary for people to be more aware of the potential risks of sun exposure.

"Erythema" or sunburn is a very common condition among fair skinned people, which occurs when the skin absorbs energy from the sun s rays. The system detects it as a harmful, intrusive force and thereby signals for extra blood to reach the affected area and restore the skin. It results in pain, swelling, blistering, itching and peeling of the skin. Not only is it a painful condition, it can also be a precursor to even more harmful diseases.
Skin cancer cases are steadily on the rise in the world, with 5 new such cases being reported every week. Due to prolonged exposure to harsh UV rays, the number of damaged cells in the body increases to such an extent that the system cannot mend it anymore. When not controlled, these damaged cells multiply, grow or divide uncontrollably. These cells can also accumulate and form a tumor.
Repeated and prolonged exposure to sun rays can also cause premature aging and wrinkling due to the degenerative damages it does to the skin s epidermis.
If one is vulnerable to sunburn, it is recommended for them to carry sunscreen at all times. The UV rays are blocked by the deflecting properties of sunscreens, thereby protecting the skin to a large degree.
It is recommended for patients to carry umbrellas, or protective clothing to cover themselves up if they are vulnerable to harsh sun s rays in the morning.
Although sun exposure can cause several problems to our skin, with proper precautions, one can be assured of safety. Sun exposure can be properly managed if one remembers to make use of these simple tips daily.
