Staying Safe
If people are outside during dangerously high temps, they can suffer from heat illness. Symptoms of heat exhaustion include:
- Dizziness
- Thirst
- Heavy sweating
- Nausea
- Weakness
To treat heat exhaustion, you should move to a cooler area, loosen any tight clothing and sip water. If symptoms don’t improve, then those experiencing heat exhaustion should seek medical attention.
If heat exhaustion isn’t treated, it can lead to heat stroke. Those suffering can experience:
- Dizziness
- Confusion
- Falling unconscious
If you’re with someone who is experiencing heat stroke, you should call 911. If someone with heat stroke doesn’t get treated quickly, they can be permanently disabled or even die from the heat.
Certain groups are more likely to suffer from heat illness than others. The elderly, people with chronic illness or who are pregnant, and children are the most vulnerable. Children and pets should not be left in the car unattended during especially hot days.
Those who have to go outside for work or exercise are advised to limit strenuous activities, take breaks in the shade and stay hydrated.
