Title : Skin diseases due to sun rays Previous topic PreviousNext Next topic

Most of the peoples love the warm sun as sun's rays make us feel good. But exposure to sun causes most of the wrinkles and age spots on our faces.  There is convincing evidence that sunlight causes skin cancer. Skin cancer can be treated and cured without serious consequences. Skin cancer is an occupational concern for people who work under the sun.

Sun exposure causes most of the skin changes that we think of as a normal part of aging. Over time, the sun's ultraviolet (UV) light damages the fibers in the skin called elastin. When these fibers breakdown, the skin begins to sag, stretch, and lose its ability to go back into place after stretching. The skin also bruises and tears more easily-taking longer to heal. So while sun damage to the skin may not be apparent when you're young, it will definitely show later in life.

Sun exposure can lead the follwoings :

1) Sunburn

2) Tanning

3) Aging

4) Wrinkles

5) Skin cancer

6) Allergic reactions

7) Aggravation of herpes simplex, cold sores, chickenpox

8) Sallowness-a yellow discoloration of the skin;

9) Elastosis-the destruction of the elastic tissue causing lines and wrinkles

10) Pre-cancerous (actinic keratosis) and cancerous (basal cell carcinoma, squamous cell carcinoma and melanoma) skin lesions-caused by loss of the skin's immune function.

If exposure to sunlight continues for several years, the damaged skin has an increased chance of developing one of the forms of skin cancer. Exposure to ultraviolet radiation increases the risk of developing these cancers (although it may not be the only cause of the disease). While the exact relationship is not 100% defined, it appears that intermittent (occasional) exposure and exposure during childhood and adolescence are likely important predictors for basal cell carcinoma, and cutaneous malignant melanoma.

 Here are few tips to protect your skin from sun

1) Use sunscreen liberally 20 minutes before you step out in sun; especially on cloudy days. Use sunscreen in adequate quantities

2) Reducing exposure to sunlight. Workers should avoid unnecessary exposure to the sun, especially to the intense midday rays between 11:00 a.m. and 4:00 p.m. during the summer.

3) Wearing Protective Clothing and Sunglasses

4) Apply on all exposed areas, do not forget your lips and ears.

5) Use an umbrella or wear a wide brimmed hat.

6) Avoid synthetic fabrics. Use light coloured cotton. It helps absorb harmful UV rays
   
7) Sit in the shade whenever possible.

8) Examining Skin Regularly. People who work under the sun should examine their skin regularly for any unusual changes.

9) Babies and children should not be exposed to sunlight without protection; they should be protected with clothing, hat, sunglasses, sun protection creams.

10) Remembering that sand reflects the sun rays and increases the chance of burning.
