As Nevada experiences longer, hotter summers, protecting ourselves and our neighbors is more important than ever. Here are a few ways to stay safe during extreme heat.

Age Matters

Anyone can experience heat-related illness, but some people are at greater risk.

• Children under age 5 can overheat quickly because their bodies do not regulate temperature as efficiently.
• Adults age 65 and older are also more vulnerable because our bodies become less effective at cooling themselves as we age.

Check in on young children, older adults, and neighbors who may need extra support during heat waves.

Medical Conditions & Medications

Certain health conditions and medications can increase the risk of heat illness.

Some medications can affect your body’s ability to cool itself or stay hydrated. If you have concerns about how heat may affect you, talk with your health care provider or pharmacist before temperatures become dangerous.

Pay Attention to the Heat Index

It’s not just the temperature, it is also the humidity.

The heat index combines air temperature and humidity to estimate how hot it actually feels to the human body. Higher humidity makes it harder for sweat to evaporate, reducing your body’s ability to cool itself.

Always check the heat index, not just the forecasted temperature.

Think Local

Heat is not experienced equally across every neighborhood.

Temperatures can vary significantly within the same city depending on tree canopy, pavement, buildings, and green space. Many communities with fewer trees and more concrete experience the urban heat island effect, which has disproportionately affected many historically underinvested neighborhoods.

Look for nearby cooling centers, libraries, community centers, or shaded parks if your neighborhood remains especially hot.

Cool Off at Night

Recovering overnight is essential during prolonged heat waves.

The effects of heat are cumulative. If your body cannot cool down overnight, your risk of heat exhaustion and heat stroke increases the next day.

Use air conditioning if available, visit a cooling center if your home stays dangerously warm, or use fans and ventilation when temperatures safely allow.

Take It Slowly

If you are traveling to a hotter climate or experiencing your first major heat wave of the season, give your body time to adjust.

Gradually increase your time outdoors over several days, drink plenty of water, take frequent breaks in the shade, and avoid strenuous activity during the hottest part of the day.

Caring for One Another

Extreme heat is one of the deadliest weather hazards in the United States, but it is also one we can prepare for.

This summer:

• Drink water regularly.
• Wear lightweight, light-colored clothing.
• Seek shade or air-conditioned spaces.
• Limit outdoor activity during the hottest hours (typically 10 a.m.–6 p.m.).
• Check on older adults, neighbors, people experiencing homelessness, and anyone who may not have reliable air conditioning.

Protecting one another during extreme heat is an act of community care. Together, we can help ensure everyone stays safe.
