Spend time somewhere cool
Use air conditioning or visit a cooled public place such as a library or cooling center. Shade and rest breaks help outdoors, but a fan alone may not keep you safe in a very hot room. Move strenuous activities to a cooler time.
Stay hydrated and check on others
Drink water regularly. If a clinician limits how much you can drink, follow that guidance and ask about a heat plan. Check on people who live alone, older adults and anyone who may struggle to reach a cool place. Never leave a person or pet in a parked vehicle.
Stop at early signs of illness
Dizziness, weakness, nausea, headache or heavy sweating can signal heat exhaustion. Stop activity, move to a cool place and cool the skin. Seek medical help if symptoms worsen, vomiting occurs or symptoms last longer than an hour.
Confusion or collapse is an emergency
Heat stroke can cause confusion, slurred speech or loss of consciousness. Skin may be sweaty or dry. Call 911 immediately and begin cooling the person with cool wet cloths while help is coming. Do not give fluids to someone with suspected heat stroke.
