A hat is always a good idea. But if you’re bald, have thinning hair or are sporting a super short hairstyle, a hat is a definite must. Hair helps protect your head from the sun, which means that if your scalp is exposed it’s at the same risk of sun damage as the rest of your skin. If you can see your scalp through your hair wear a hat or at the absolute minimum use a sunscreen formulated to protect the hair and scalp.
Warmer weather means that plants are pollinating and that can cause problems for allergy sufferers. When choosing your workout location or running, hiking or bike route, steer clear of areas with high pollen levels. Also, avoid outdoor exercise when pollen counts are highest (between 5 a.m. and 10 a.m. and early evening) and exercising on days when pollen counts are particularly bad (check your local air quality forecast). After your outdoor workout be sure to shower well, and consider nasal irrigation to help reduce allergy symptoms. Don’t be afraid to skip a workout or two if your symptoms are especially bad.
