You might have noticed that it’s been pretty hot outside — with temperatures climbing into the 90s. For people who exercise regularly, you might be wondering — is it safe to exercise in the heat?

“Exercising in the summer should be approached with some caution and planning, but it can be done,” according to Lauren Conley, a clinical exercise physiologist. She offers these tips to stay safe when exercising this summer.

Modify Your Workout

  • If you plan to exercise outdoors, do it in the cooler morning or evening hours
  • On very hot, humid days slow down from your regular workout pace
  • If the temperature is above 80° F and the humidity above 80 percent, postpone outside activity until things cool off

Consider Your Heart Health

“If you have a history of heart disease, you should monitor your exercise heart rate and stay within the ranges prescribed by your physician, exercise physiologist or physical rehabilitation therapist to help you avoid overworking the heart,” said Lauren.


If you plan to exercise longer than 30 minutes, follow these hydration tips.

  • Drink 8–12 oz. of water 20–30 minutes prior to exercise plus 6–10 oz. additional every 30 minutes of exercise to help prevent dehydration
  • For most people, water is a great fluid replacement
  • Avoid sports drinks to cut unnecessary sodium, sugar and calorie intake unless you sweat excessively

Dress for the Weather & Activity

  • Avoid long sleeved sweatsuits or other material that does not breath well, as this prevents the evaporation of sweat which cools the body down
  • Wear loose fitting cotton T-shirts, shorts and a brimmed hat when exercising outdoors

Try These Easy Indoor Exercises

If you do not have a gym membership, try walking laps around your house for a set amount of time or walking up and down your stairs for a great indoor workout.

As always, consult your physician before beginning any new exercise program. Be heart-smart — stay active and reap the benefits of regular exercise all year round!
