Stay Safe When Exercising in Hot Weather

Many people enjoy outdoor activities—walking, gardening, playing tennis. As the weather gets warmer, it’s important to play it safe when playing outside. Too much heat can be risky for older adults and people with health problems. Being hot for too long can cause hyperthermia—a heat-related illness that includes heat stroke and heat exhaustion.

Go4Life has safety tips if you want to be active when it’s hot outside:

  • Check the weather forecast. If it’s very hot or humid, exercise inside with Go4Life videos online, or walk in an air-conditioned building like a shopping mall, or try other indoor activities.
  • Drink plenty of liquids. Water and fruit juices are good options. Avoid caffeine and alcohol. If your doctor has told you to limit liquids, ask what to do when it is very hot outside.
  • Wear light-colored, loose-fitting clothes in natural fabrics.
  • Dress in layers so you can remove clothing as your body warms up from activity.
  • Get medical help right away if you think someone might have a heat-related illness and know the signs.
