UV rays are less intense in winter than in summer.
True and false.
There is a tendency to think that Uvs are less dangerous in winter than in summer, which is not true. Indeed, the UVB (responsible for sunburn, tanning and certain skin cancers) are less intense during this season, but not the UVA (responsible for skin aging, some skin cancers) ... so be careful ! In addition, in winter, the snow reflects the rays, making it even easier for our exposed skin surfaces. Let's be vigilant even more in the winter, and wear sunscreen ... in any season!
