Sunburn

By Dr Bhatti, M.B.B.S.D.C.H.R.C.P.S.I

Sunburn is caused by overexposure to ultraviolet (UV) radiation, commonly from the sun's rays. Exposure of the skin to lesser amounts of UV will often produce a suntan.

Mild symptoms of sunburn include: hot, red skin and eyes, sensitivity to light, blisters on the skin and flaking skin. Severe exposure can result in: pain, swelling of affected area, chills and fever, nausea, shock, light hypersensitivity and decreased visual clarity.

Sunburn is better prevented than treated. There are some very effective sunscreens that protect from UVA and UVB (long and short wavelengths of ultraviolet light), which are the components of sunlight responsible for burning and cancerous changes in the skin.

Wearing a sunscreen with high sun protection factor (SPF) is highly recommended. The higher SPF numbers indicate greater protection. The lighter your skin tone, the higher the SPF should be. Most doctors recommend a sunscreen SPF level of 50 or greater your dermatologist and friendly pharmacist can advise you.

Apply sunscreen 15-30 minutes before sun exposure. Reapply every hour and after swimming. Make-up is now available with sun screening protection. Sunscreen, protective clothing, and ultraviolet-protected sunglasses are all recommended to prevent excessive sun exposure. Wear muted colours such as tan and wear a hat..
