Water safety
Some people turn to local rivers to cool off, but drowning is a real concern. Please use caution and wear a personal flotation device (PFD) on the water. Find deals on affordable lifejackets. And if you want to swim, choose a safer location – visit a local pool or lifeguarded beach instead.
Recognizing heat exhaustion and heat stroke
When people's bodies can't cool themselves quickly enough it can cause heat exhaustion. Symptoms of heat exhaustion include muscle cramps, weakness, dizziness, headache, nausea and vomiting. If you see someone with signs of overheating, move the person to a cooler location, have them rest for a few minutes and then slowly drink a cool beverage. Get medical attention for them immediately if they do not feel better.
Heat exhaustion can lead to heat stroke, which can cause death or permanent disability unless treated immediately. Symptoms of heat stroke include:
- An extremely high body temperature (above 103°F)
- Red, hot, and dry skin
- Rapid, strong pulse
- Nausea, confusion and unconsciousness
