Heat
Drink lots of water frequently (don’t drink a whole gallon at once). For adults, an extra pint of fluids every 30 minutes during exercise.
When it is hot, limit the time that you spend outside between the hours of 10 a.m. and 5 p.m. That is the time of the worst air quality and the highest risk for heat injuries such as heat exhaustion and heat stroke.
Exercise with care outside until you are accustomed to the heat. Even elite athletes have to be careful when summer suddenly arrives. Go at half pace for the first week over 90 degrees and slow down when there is high heat and humidity.
Sun
Wear sunscreen – reapply it every time you think of it. Even if it says it lasts all day. Use SPF 15 or greater. Remember that wet, light, thin clothing transmits sunlight.
Don’t even think of using a tanning bed or booth. You will deserve the skin conditions you will contract from them!
Wear sunglasses every time you are outside. Polarized lenses cut down on eyestrain even if there are some hazy clouds and no ‘bright’ sunlight.
Wear a hat – not just a visor. Cloth is better than just sunscreen, and it covers your scalp between the hairs. It can help keep you from getting more wrinkles on your face.
Bugs
Protect against bug bites with DEET. Use preparations with 25-30% DEET to last for a few hours. 10% DEET protects for less than an hour. More than 50% DEET may cause skin irritation.
Avoid dressing in bright or floral prints. Do not use scented soaps, perfumes or hair sprays if you will be around bugs, or else they will be around you.
