This is the question that can arise - even in March - in view of sunny days that France is experiencing. From when to protect themselves from UV? Which is especially relevant?
Prevention messages often pounding the same thing: we must protect from the sun in all cases. It is true that vigilance is required vis-à-vis UV which are considered the leading cause of melanoma, cancer of the most dangerous skin.
This discourse is now better explained and qualified by Prof. Cesarini, head of the Solar Security Association, during an interview in Le Figaro. What's he saying ?
No need to apply a sunscreen in all cases. In March and early April, the sun is moderate, it is not necessary to protect themselves.
The heat is not a criterion for whether to or not, to protect themselves. It is essentially the UV index to look out.
The UV index provides information on the radiation intensity, it is 1 to 11. In metropolitan France - off mountains - in March or early April, UV radiation is 2 or 3, that is to say low. In this case, it is not necessary to protect against the sun.
- This is from May, when UV radiation can go up to 5 or 6 or 7 that must be protected.
FYI, is broadcast daily information on UV radiation and available online.
