Ozone: When the state issues an ozone alert, no jogging in the heat of the day. If you’re playing or working outdoors, get out of the sun every half hour and rest. Drink plenty of liquids.

Sunburn: Leading cause of skin cancer, which is on the rise in Maine. Use sunblock (at least 30 SPF) and cover up – hats, long sleeves – if you’re out for more than a half hour.

E. coli: Grilling? Make sure all meat is thoroughly cooked. If not, it can give you a nasty bacterial infection. Be especially careful with ground beef.

Ticks: Ick. If you’re out in the woods, wear DEET repellent and cover your skin as much as possible. Check for ticks afterward. Deer ticks cause Lyme disease, which can be debilitating.
