Today’s edition of Scicurious’ Friday Weird Science covers a study that proves beards provide considerable coverage from UV rays. While the level of protection varies based on several beard factors – length, thickness, amount of face covered – the results are still positive:
“What you can see here is the exposure ratio, after 1 hour in the sun with the face angled up to receive the light (described as horizontal, they did 1 hour at most angles, except for the 25ish degree angle, which had 2 hours of exposure). You can see that beard presence significantly decreased the amount of UV exposure. When teased apart, the longer beards provided more protection.”
