Understanding UVB Rays and the way they trigger sunburn.

UVB rays are the main explanation for a sunburn that comes from the solar. The SPF in your sunscreen product primarily describes its safety in opposition to these UVB rays.  UVB ray depth varies throughout the yr and in line with the place you’re on the planet.  Which means it’s worthwhile to know when the UVB rays are most intense to know your sunburn threat. UVB rays are most intense:

  • throughout the center of the day between 10 am and 3pm

Clouds don’t actually block a lot of the UVB rays they usually penetrate into water too.

Understanding UVA Rays and the way they trigger sunburn.

UVA ray depth doesn’t differ like UVB.  UVA rays are out all day, all yr, all over the place on the planet.  They’re mirrored off sand and snow and penetrate into water.
