Why the need for sun protection

Protection from the Sun

Why the need for sun protection

Prolonged exposure to the sun’s rays may cause side effects over the short and long term. The most obvious effects are sunburns, which can be mild to severe. Yet, overexposure to the sun can also cause wrinkles or premature aging of the skin. There can also be other more serious chronic effects such as skin cancer, cataracts, etc. There are two types of UV rays that are dangerous to skin:
• UVA: wrinkles and premature aging of the skin
• UVB: skin cancer (white or brown rough lesions)
Remember that the sun’s rays are more intense at the beach and at higher altitudes and may require more intense protection.
