❤️ “Heart Attack Surge”: What Cardiologists Actually Want You to Avoid in Extreme Heat
The headline is dramatic, but hot weather can genuinely put extra stress on the cardiovascular system, especially in older adults and people with heart disease. Recent American Heart Association guidance notes that extreme heat is associated with increased cardiovascular events, including heart attacks, strokes and worsening heart failure.

☀️ In very hot weather, avoid these 5 things
1. Don’t do strenuous exercise during the hottest part of the day.
Heat makes the body work harder to cool itself. If you need to exercise outdoors, choose a cooler time and take frequent breaks in shade or air conditioning. (www.heart.org)
2. Don’t allow yourself to become dehydrated. 💧
Heavy sweating causes fluid loss, which can contribute to dizziness, low blood pressure and cardiovascular strain. Drink fluids regularly, unless your doctor has specifically restricted your fluid intake.
3. Don’t ignore unusual symptoms.
Chest pressure or pain, shortness of breath, unusual sweating, nausea, dizziness or sudden extreme weakness can indicate a serious cardiovascular problem. Don’t assume they’re “just the heat.”
4. Don’t drink excessive alcohol in extreme heat.
Alcohol can worsen dehydration and impair judgment about how overheated you are. The AHA recommends avoiding alcoholic beverages in hot conditions. (www.heart.org)
5. Don’t change your heart medications yourself. 💊
This is particularly important. Diuretics, beta-blockers, ACE inhibitors, ARBs and some calcium-channel blockers can affect the body’s response to heat. Do not skip or reduce them without medical advice. (CDC)
🚨 When it’s an emergency
If someone develops chest pain/pressure, severe shortness of breath, fainting, confusion, or other symptoms suggestive of a heart attack, seek emergency medical care immediately.
For heat stroke—such as very high body temperature, confusion, fainting or severe neurological symptoms—emergency treatment is also required. (www.heart.org)
Bottom line: Heat doesn’t mean you must stay indoors all summer, but if you have cardiovascular disease, stay cool, hydrate appropriately, avoid strenuous activity in peak heat, and continue prescribed medications unless your clinician tells you otherwise. (CDC)
