June 18, 2026 · The Clime Team

Heat waves pose significant health risks, especially for those unaccustomed to extreme heat. Understanding how to stay safe during these periods is crucial.

What Is a Heat Wave?

A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity. These conditions can lead to serious health issues if precautions aren't taken.

How Can I Stay Cool During a Heat Wave?

Stay Indoors: Limit outdoor activities during peak heat hours, typically between 10 a.m. and 4 p.m.
Use Air Conditioning: If possible, stay in air-conditioned environments. If your home lacks air conditioning, consider visiting public places like malls or libraries.
Wear Appropriate Clothing: Opt for lightweight, loose-fitting, and light-colored clothing to reflect heat.
Use Fans Wisely: Fans can be effective when indoor temperatures are below 90°F (32°C). However, in higher temperatures, fans may not prevent heat-related illnesses.

How Can I Stay Hydrated During a Heat Wave?

Drink Plenty of Fluids: Consume water regularly throughout the day, even if you don't feel thirsty. Avoid alcohol and high-sugar drinks, as they can dehydrate you.
Monitor Urine Color: Light yellow or clear urine typically indicates adequate hydration.

What Are the Symptoms of Heat-Related Illnesses?

Recognizing the signs of heat-related illnesses is vital:

Heat Exhaustion: Symptoms include heavy sweating, weakness, dizziness, nausea, and headaches.
Heat Stroke: A more severe condition with symptoms like confusion, loss of consciousness, and a body temperature above 103°F (39.4°C).

If you or someone else exhibits these symptoms, seek medical attention immediately.

How Can I Protect Vulnerable Individuals During a Heat Wave?

Certain groups are more susceptible to heat-related illnesses:

Check on At-Risk Individuals: Regularly check on family, friends, and neighbors, especially those with chronic health conditions, the elderly, and young children.
Use a Buddy System: Ensure someone is aware of your activities and well-being during extreme heat periods.

How Can I Prepare My Home for a Heat Wave?

Limit Heat Sources: Use your stove and oven less to maintain a cooler indoor temperature.
Seal Windows and Doors: Keep them closed during the hottest parts of the day to prevent heat from entering.
Use Cooling Centers: If your home lacks air conditioning, locate nearby cooling centers or public places to stay cool.

How Can I Stay Safe While Exercising During a Heat Wave?

Limit Outdoor Activity: Reduce physical exertion during peak heat hours.
Wear Sunscreen: Protect your skin by applying sunscreen with an SPF of 15 or higher.
Pace Yourself: Start activities slowly and gradually increase intensity.
Stay Hydrated: Drink water before, during, and after exercise.

How Can I Stay Informed About Heat Risks?

Monitor Local Weather: Stay updated on heat advisories and warnings in your area.
Use the CDC HeatRisk Dashboard: Enter your zip code to view heat risk forecasts and recommended actions.

How Can I Help Others During a Heat Wave?

Check on Vulnerable Individuals: Ensure that those who are elderly, have chronic health conditions, or live alone are safe and have access to cooling resources.
Share Information: Educate friends and family about heat safety measures.

How Can I Recognize and Treat Heat-Related Illnesses?

Heat Exhaustion: Move the person to a cooler place, have them drink water, and apply cool, wet cloths to their body.
Heat Stroke: Call emergency services immediately. While waiting for help, move the person to a cooler area, remove excess clothing, and apply cool, wet cloths to their body.

By following these guidelines, you can significantly reduce the risks associated with heat waves and ensure your safety and the safety of those around you.
