When the summer heat rises, your body works harder to stay cool. But sometimes, it can’t keep up. That’s when signs of heat exhaustion start to appear—and recognizing them early can make all the difference. Here’s how to spot the warning signs before it turns into something more serious.
What Is Heat Exhaustion?
Heat exhaustion happens when your body overheats and loses too much water and salt through sweating. It’s a warning stage before heat stroke, which is a medical emergency.
The good news? If you act fast, heat exhaustion can be treated at home—no ER required.
7 Warning Signs to Watch For
If you or someone nearby is outdoors in hot weather, keep an eye out for these symptoms:
- Heavy sweating
- Dizziness or fainting
- Nausea or vomiting
- Cool, pale, clammy skin
- Fast, weak pulse
- Muscle cramps
- Tiredness or headache
What to Do If You Notice These Symptoms
If you suspect heat exhaustion:
- Move to a cool, shaded, or air-conditioned area.
- Loosen clothing and lie down.
- Sip cool water slowly—not ice-cold, which may cause cramps.
- Use a wet cloth or fan to cool down the body.
❗ Important: If symptoms don’t improve in 30 minutes or get worse, seek medical help immediately.
Who’s Most at Risk?
Certain groups are more vulnerable in extreme heat:
- Older adults and young children
- People with chronic illnesses (like heart disease or diabetes)
- Outdoor workers and athletes
- Those without reliable access to AC
Conclusion
Recognizing the signs of heat exhaustion quickly can protect your health and prevent a trip to the hospital. Stay alert, stay hydrated, and know when it’s time to rest and cool down.
