Protect Your Heart from the Heat

Beth Callahan Editor

KINGS MILLS, OH -- Summer has arrived, and now is the time to embrace the fun of sunny days and outdoor activities, but it is important to remember that excessive heat can pose significant risks to heart health, particularly for certain individuals. Mercy Health—Cincinnati is calling out the need for awareness and proactive measures to protect hearts during the excessively hot weather.

Those with existing heart conditions, individuals over the age of 50, and people who are overweight are at an increased risk of experiencing heat-related illnesses such as heat exhaustion and heat stroke. In high temperatures, the heart works harder and beats faster to regulate body temperature. It’s crucial to understand how to care for your heart during these hot and humid days.

To maintain heart health in the heat, please remember the following:

1. Stay Hydrated:

Hydration is vital. Drink plenty of water throughout the day, even if you’re not engaging in physical activity. Dehydration can lead to irregular heartbeats and poses a significant risk for those with heart-related issues.

2. Dress Lightly:

Choose loose-fitting, light-colored clothing made from breathable fabrics like cotton. These materials facilitate sweating and help keep the body cool, reducing stress on the heart.

3. Eat Wisely:

Opt for lighter meals during the summertime. Heavy foods can strain your digestive system and put a strain on your heart. Favor grilled vegetable kabobs and lean proteins like turkey burgers or fish, such as tuna and salmon, which offer heart-healthy omega-3 fatty acids.

4. Keep Cool:

Swimming or staying near water can provide relief from the heat. If water access is limited, use fans or air conditioning. Ice packs or cold compresses can also be beneficial in maintaining a cool body temperature.

5. Take Breaks:

If you begin to feel faint or dizzy while outdoors, find a cool or shaded area to rest and elevate your feet to promote blood circulation. Regular breaks during any light exercise are essential for hydration and overall well-being.

6. Review Medications:

Individuals with heart conditions should consult their health care provider to ensure their medications are safe for use in hot weather, as some can lead to dehydration or changes in heart rate.

As we enter the summer months, Mercy Health—Cincinnati encourages folks to be proactive in protecting their heart health. Don’t hesitate to schedule a physical check-up to ensure you’re ready for the heat and to discuss any concerns regarding heart health and medication safety.
