While extreme heat can impact everyone’s heart, older people and those with preexisting heart issues are especially at risk.
CLEVELAND, OH (CLEVELAND CLINIC) - With summer here, many of us are getting outside more to enjoy the sunshine. But as temperatures soar, it’s important to remember how extreme heat can take a toll on our hearts.
It’s also important to remember that certain blood pressure medicines as well as other medications can increase your risk of dehydration.
“People exposed to the heat or humidity tend to experience dehydration, and dehydration leads to an increased heart rate, meaning your heart beats faster than usual. This can increase inflammation in the body,” explained Carlos Gonzalez Lengua, MD, interventional cardiologist at Cleveland Clinic, Florida.
If you do go outside, you want to avoid doing any strenuous activities and think about going to places where you can stay cool.
Dr. Gonzalez said the inflammation from your body working harder to cool you down can possibly cause blood clots, which can lead to a heart attack or stroke. And while extreme heat can impact everyone’s heart, older people and those with preexisting heart issues are especially at risk. It’s also important to remember that certain blood pressure medicines as well as other medications can increase your risk of dehydration. To avoid issues during a heatwave, Dr. Gonzalez said it’s best to check the weather and try to stay inside at the hottest points of the day.
If you do go outside, you want to avoid doing any strenuous activities and think about going to places where you can stay cool.
“If you really want to get out of the house, maybe go to the mall, a grocery store, or local pool. Make sure you’re keeping yourself hydrated as well,” Dr. Gonzalez said.
If you start feeling fatigued on a hot day, Dr. Gonzalez stressed it’s crucial to promptly find a way to cool down and drink plenty of water. Don’t hesitate to call 911 if you start experiencing symptoms such as chest pain.
