Deflect overexposure. Sun protection is a necessity. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense. Be attentive! The reflective property of snow can nearly double the Sun's UV radiation.
