How Can I Protect Myself During a Heat Wave?

1. Stay Hydrated: Drink plenty of cool fluids, especially water, even if you don't feel thirsty. Avoid alcohol and caffeine, as they can dehydrate you. (consumerreports.org)

2. Seek Shade and Stay Indoors: Limit outdoor activities during peak heat hours, typically between 11:00 AM and 4:00 PM. If you must be outside, wear light-colored clothing and a wide-brimmed hat. (apha.org)

3. Use Cooling Devices: Utilize fans, air conditioning, or cool showers to help lower your body temperature. If you don't have air conditioning, consider visiting public places like libraries or shopping centers to stay cool. (latimes.com)

4. Monitor Weather Alerts: Stay informed about local weather conditions and heat advisories. The National Weather Service provides updates and warnings for extreme heat events. (consumerreports.org)

What Are the Signs of Heat-Related Illnesses?

Recognizing the symptoms of heat exhaustion and heat stroke is vital:

• Heat Exhaustion: Symptoms include heavy sweating, weakness, dizziness, nausea, and headache. Move to a cooler place, drink water, and rest.

• Heat Stroke: Symptoms include high body temperature, confusion, and loss of consciousness. This is a medical emergency; call 911 immediately. (pbs.org)
