Extreme heat can affect your body in ways you may not expect. Hot temperatures, high humidity, direct sunlight, and warm nights can make it harder for your body to cool down.
Humidity, direct sun, airflow, and warm nights can all affect how hard the body works to stay cool.
When temperatures stay high overnight, the body may have less time to recover from the heat.
A home without enough cooling can become risky, especially for older adults or people with chronic conditions.
Weather alerts and local heat-risk tools can help patients plan ahead before conditions become harder to manage.


1. Know What To Expect From The Weather
Look for local heat advisories, Extreme Heat Watches, Extreme Heat Warnings, or HeatRisk updates before making plans.
2. Know Your Heat Risk
Age, medications, chronic health conditions, mobility, outdoor activity, and access to cooling can all affect heat safety.
3. Plan Where You Can Cool Down
Know where you can go if your home becomes too hot, such as an air-conditioned room, a family member’s home, a library, or a local cooling center.
UNDERSTAND THE BASICS
Heat does not affect everyone the same way. A temperature that feels manageable for one person may be harder for someone who is older, lives with chronic health conditions, takes certain medications, works outdoors, or does not have a cool place to rest.
Humidity can also make hot weather feel harder. When the air is humid, sweat may not cool the body as well. This is why the “feels like” temperature can matter when planning your day.

Heat risk can change from day to day. You may feel fine one afternoon and feel more affected the next day if the heat continues, sleep is poor, fluids are limited, or symptoms begin.
Heat safety starts before symptoms appear. A little planning can help you make safer choices before the day becomes harder to manage.
A simple routine can help you and your family prepare before very hot weather becomes more difficult.
Check heat alerts before hot days
Know where you can cool down
Keep water nearby unless your clinician has limited fluids
Plan outdoor activities for cooler times
Check on older adults, neighbors, or family members who may need help
Ask your care team how heat may affect your health conditions
Heat can become more dangerous when people wait until symptoms are strong before changing plans.
Staying in a hot room for long periods
Ignoring heat alerts
Doing strenuous activity during the hottest part of the day
Waiting until you feel very thirsty to think about fluids
Assuming indoor heat is always safe
Relying only on a fan when the home is very hot
Planning ahead can make hot days feel less stressful and easier to manage.
