Beat the Heat: Summer Safety Tips for CHF Patients on Diuretics

Managing congestive heart failure (CHF) requires ongoing attention, and even more so during the hot summer months. If you’re living with CHF and taking diuretics, warm weather can put extra stress on your heart and increase the risk of dehydration and heat-related illness.

Here’s how you can stay safe, cool and well-supported this season.

Why Heat Poses a Risk for CHF Patients

When the temperature rises, your body has to work harder to keep cool. For individuals with CHF, this can lead to increased swelling and make the heart work even harder. Diuretics, while helpful for managing fluid, can contribute to dehydration, especially in the heat. That’s why careful monitoring of fluid intake and health symptoms is so important during the summer.

Smart Tips for Food & Drink

Managing fluid intake doesn’t mean avoiding hydration; it means doing it thoughtfully. Consider the following tips:

• Limit salt to help control thirst; look for low-sodium options when shopping.
• Measure fluids and sip them throughout the day instead of drinking large amounts at once.
• Eat cold fruits as a refreshing way to stay hydrated.
• Freeze beverages and sip slowly as they melt.
• Suck on sugar-free candy or chew gum to relieve dry mouth without extra fluids.
• Use smaller cups to better manage fluid portions.
• Don’t forget that soups, ice cream and other liquid-based foods count toward your daily fluid total.

Medication Awareness in the Heat

Several heart medications—such as beta blockers, ACE inhibitors, ARBs, calcium channel blockers and diuretics—can make the body more sensitive to heat. Talk with your healthcare provider about how your medications may affect you in the summer and what precautions to take.
