Beating the Heat: How to Stay Safe in Georgia's Summer Heat

By late June, Georgia heat stops being a nuisance and starts being a health risk. Heat index values in the Douglasville and West Atlanta area regularly climb into the upper 90s and low 100s through July and August, and every year emergency rooms see preventable heat-related illness — in outdoor workers, athletes, older adults, and people who simply underestimate how fast heat can overwhelm the body.

Heat Exhaustion vs. Heat Stroke: Know the Difference

Heat exhaustion is your body's warning sign: heavy sweating, weakness, cool and clammy skin, a fast but weak pulse, nausea, headache, and muscle cramps. It's serious, but reversible with prompt action — move to a cool place, sip water, and loosen clothing. Heat stroke is a medical emergency. Warning signs include a body temperature above 103°F, hot and dry or flushed skin, a rapid and strong pulse, confusion, slurred speech, or loss of consciousness. If you suspect heat stroke, call 911 immediately — this is not a 'wait and see' situation.

Who's Most at Risk

Certain groups face higher risk in extreme heat: adults over 65, people with chronic conditions like heart disease, diabetes, or high blood pressure, anyone taking diuretics, beta-blockers, or certain psychiatric medications, outdoor workers and athletes, and people without reliable access to air conditioning. If you fall into one of these groups, it's worth a conversation with us about how your specific health conditions or medications affect your heat tolerance.

Hydration: More Than Just Water

Plain water is good, but on the hottest days — especially if you're sweating heavily during yard work, sports, or outdoor labor — you also need to replace electrolytes (sodium, potassium, magnesium). Signs you're already behind on hydration include dark yellow urine, dry mouth, fatigue, and dizziness when standing. A general rule: drink before you're thirsty, and don't wait until you feel bad to start hydrating.

Medications That Increase Heat Risk

Several common medications make it harder for your body to regulate temperature or increase dehydration risk, including diuretics ('water pills') for blood pressure, certain antidepressants and antipsychotics, antihistamines, and some ADHD medications. This doesn't mean you should stop taking them — it means you need to be more deliberate about hydration and heat exposure. If you're on any of these and spend time outdoors, ask us at your next visit how to adjust your routine safely.

Practical Heat Safety Habits

Schedule outdoor activity for early morning or evening, when temperatures are lower. Wear lightweight, light-colored, loose-fitting clothing. Take breaks in shade or air conditioning every 15–20 minutes during sustained outdoor work. Never leave children, pets, or anyone in a parked car, even briefly — vehicle interiors can reach dangerous temperatures within minutes. Check on elderly neighbors or family members during heat waves, especially those who live alone.

When to Come In, and When to Go to the ER

If you've had a heat exhaustion scare and want to make sure your medications, blood pressure, and hydration plan are heat-safe for the rest of the summer, schedule a visit with us. But if you or someone with you shows signs of heat stroke — confusion, very high body temperature, hot dry skin, or fainting — don't wait for an appointment. Call 911 or go to the nearest emergency room immediately. Heat stroke can cause organ damage within minutes.

Stay Ahead of the Heat This Summer

Most heat-related illness is preventable with the right precautions — and a quick conversation with your primary care doctor can help you understand your personal risk factors.
