Unlike the popular belief a tan is in fact an unhealthy skin reaction to sun damage. Read further to know ‘the darker side of deliberately darkening your skin.’
What is a skin tan?
A tan is typically developed when the skin produces more melanin than normal. Upon exposure to sunlight, the ultraviolet radiation in sunlight penetrates the skin causing damage to the skin cells. In response to the damage, the skin cells produce melanin cells to combat further damage. It is these melanin cells that give your skin its darker color or a tan.
Why is tanning not safe?
- Tanning causes photoaging which results in premature aging of the skin cells giving your skin a leathery look and wrinkles.
- Exposing yourself to sun might cause acute sunburns which are often very painful
- Acute sunburns may increase the risk of melanoma.
- As the skin cells damaged by UV cells attempt to repair, there might be some unwanted DNA changes (DNA mutations) that may predispose you to a variety of skin cancers.
The Take Home Message - There is no health reason ever to get a tan. Avoid exposure to harsh sunlight or prolonged exposure to sun unless unavoidable. Take enough precautions to protect your skin from the harmful UV radiations and tanning.
- Always apply a broad spectrum sunscreen (at least SPF 15) 30 minutes before going out in the sun and repeat application every two hours while you are exposed to the sun.
- Avoid sun exposure during peak sunny hours.
