Heatwaves and Heartbeats: Protect Your Heart Health this Summer
6/17/2024
Gadsden, AL, June 17, 2024 – Summer 2024 is predicted to bring on the heat which can put extra stress on your heart. For every degree body temperature rises, the heart beats approximately 10 beats per minute faster, according to the National Institute of Health. That’s why in hot temperatures it becomes harder for the body to cool off, especially for those with chronic health conditions like heart disease, hypertension or atrial fibrillation (AFib).
“Our bodies get rid of excess heat through sweat. Hot, humid weather forces the heart to work harder to pump more blood to the skin,” said Peter Scalise, III , M.D., a Gadsden Regional Medical Center affiliated cardiologist. “While it’s important to stay active during summer months, I’ve seen that my patients are more prone to experience dehydration if they are not careful to drink plenty of fluids such as water or sports drinks.”
Another factor affecting heart patients is the fact that certain medications interfere with the body’s response to heat regulation.
“Beta blockers can blunt the needed increase in circulation to get rid of excess heat, increasing the likelihood of heat exhaustion,” said Dr. Scalise. “Diuretics can also make you more likely to develop dehydration.”
Dr. Scalise emphasizes the importance of continuing to take medication as prescribed and suggests working with your cardiologist to come up with a heart health plan before the weather changes, including:
- Water intake. Too little water consumption can lead to dehydration, and too much can throw off electrolytes.
- Diet. Minerals like sodium, potassium and magnesium are depleted while sweating. It’s important to replenish electrolytes through proper supplementation and nutrition.
- Fitness routine. Avoid working out during peak heat hours, or stay indoors or in the shade throughout the day.
- Attire. Lightweight, dry-fit clothing repels sweat and allows air to circulate to keep skin cooler.
Warning signs that your body isn’t keeping up with the heat include:
- High body temperature above 103°F
- Red, hot, dry skin
- Inability to sweat
- Rapid pulse
- Headache
- Dizziness or fatigue
- Nausea or vomiting
- Disorientation
- Passing out
Anyone exhibiting more than one of these symptoms may be experiencing heat stroke and should call 911 immediately. While waiting for medical attention, do not consume fluids, and continue efforts to get the body temperature to fall below 102°F, such as moving into the shade, taking a cool (not cold) bath or shower, spraying off with a hose or fanning to move air.
