The What’s Up Docs podcast from the BBC is an entertaining but factual podcast about health presented by two doctors, Chris and Xand van Tulleken (brothers and twins!) who find out to their dismay that they were wrong about the dangers of getting a nice healthy colour from the sun.
A tan occurs when UV radiation damages skin cells, causing them to produce more melanin as a protective response. This process involves DNA damage to skin cells, which can accumulate over time and potentially lead to skin cancer.
Sunburn is obviously harmful and painful. Even one blistering sunburn in childhood can double your lifetime risk of melanoma.
It’s a bit late for my Irish readers, as we had cloudless skies and a hot sun last week. Temperatures reached 25C where I was, so I slapped on the factor 50 sunscreen and made sure I was wearing a hat when I was outside. Many years ago, a neighbour died of skin cancer at the age of 52, only a few years older than I am now.
The Met Éireann UV Index page will show you what the UV index in Ireland is. If it’s 3 or over, you should be covering up with clothing or sunscreen. It’s quite alarming that the difference between a clear sky and a cloudy sky is 1-2 or 8-10 on that index.
