When the Weather Heats Up, Stay Cool for the Heart
Summer means more time to do activities such as taking long early morning walks or working in the garden. But it’s important to be aware of the temperature outside.
That’s because heart failure places someone at a higher risk for heat-related illnesses such as heat stroke. Heat stroke is a life-threatening condition that occurs when the body can’t regulate its temperature.
Why is the risk higher? In heart failure, the cardiovascular and nervous systems don’t work as they should. Research suggests that this affects the body’s ability to maintain temperature control. Also, medicines used to treat heart conditions may make it harder for the body to cool itself by perspiring.
Watch for warning signs
Heat stroke is an emergency. Those suffering symptoms need to move to a cool place and get medical help right away. Symptoms of heat stroke include:
- A body temperature above 103°F (39.4°C)
- Red, hot, dry, or damp skin
- A rapid, strong pulse
- A throbbing headache
- Dizziness, nausea, or confusion
A little prevention goes a long way
Guard against heat stroke by:
- Being aware. Ask a healthcare provider if certain medicines make someone more likely to get heat-related illness.
- Drinking plenty of fluids each day. Don’t have drinks with caffeine, alcohol, or lots of sugar. If the provider limits liquids, ask how much should be drank when it’s hot.
- Wearing lightweight, light-colored, loose-fitting clothing.
- Staying in an air-conditioned place as much as possible. If the home does have not air conditioning, go to a mall, the movies, or a friend’s house. Spending a few hours in air conditioning can help the body stay cooler when going back into the heat.
- Taking a cool shower or bath.
