Hot weather can place additional strain on your heart, especially if you are over age 50, overweight, or living with heart disease. Understanding how heat affects your body and taking proper precautions can help you stay active and safe during warmer months.
Before starting or changing an exercise routine, talk with your healthcare provider. Certain heart medications, including beta blockers, ACE inhibitors, calcium channel blockers, and diuretics. All can affect how your body responds to heat.
Why Heat Can Be Risky
High temperatures cause your heart to work harder to keep your body cool. Sweating leads to fluid and electrolyte loss, which can increase stress on the cardiovascular system.
Older adults are especially vulnerable to dehydration and heat-related illness. Even if you don’t feel thirsty, your body may already be losing essential fluids.
Safe Ways to Stay Active in Hot Weather
You can still maintain a heart-healthy lifestyle in the heat, just adjust your routine.
- Avoid outdoor activity during peak heat hours (typically noon to 3 PM)
- Exercise early in the morning or later in the evening
- Consider indoor options like malls, fitness centers, or indoor tracks
- Use the buddy system for safety and motivation
Dress for the Heat
Proper clothing can make a big difference in comfort and safety.
- Wear lightweight, light-colored, breathable fabrics
- Choose moisture-wicking socks and well-ventilated footwear
- Protect your head with a hat and your eyes with sunglasses
- Apply sunscreen (SPF 15 or higher) and reapply every two hours
Stay Hydrated
Hydration is critical for heart patients in hot weather.
- Drink water before, during, and after activity
- Avoid excessive caffeine and alcohol, which can increase dehydration
- Take regular breaks in shaded or air-conditioned areas
