Understanding High Heat: Why It Matters
Extreme heat isn’t just uncomfortable—it’s a serious health risk. According to health experts, hot ambient conditions and heat stress can increase mortality and morbidity, worsen existing health conditions, and even negatively affect mental health. As climate change continues, heat waves are becoming longer, more frequent, and more intense, making it crucial for everyone to know how to protect themselves and those around them.

How High Heat Affects Your Body
When temperatures climb, your body must work harder to stay cool. This can lead to a range of health issues, from mild discomfort to life-threatening emergencies. Here’s what happens:
1. Dehydration
Excessive sweating in hot weather causes your body to lose fluids and electrolytes, leading to dehydration. Symptoms can include:
- Headaches
- Dizziness
- Confusion
- Dry mouth
- Decreased urination
- Fatigue
Dehydration can also worsen existing health conditions and make you more vulnerable to other heat-related illnesses.
2. Heat Exhaustion
If your body can’t cool itself efficiently, you may develop heat exhaustion. Signs include:
- Heavy sweating
- Weakness
- Nausea or vomiting
- Muscle cramps
- Fainting
- Moist skin
Heat exhaustion should never be ignored—it can quickly progress to heat stroke, a medical emergency.
3. Heat Stroke
Heat stroke is the most severe heat-related illness. It happens when your body temperature rises above 104°F (40°C) and can’t cool down. Symptoms include:
- Hot, dry skin (no sweating)
- Confusion or loss of consciousness
- Seizures
- Rapid pulse
Heat stroke can be fatal. If you suspect someone is experiencing heat stroke, call emergency services immediately.
4. Heart and Blood Pressure Changes
High heat can cause your heart to beat faster as it works to cool your body. Blood vessels dilate, which can lower blood pressure and lead to dizziness or fainting—especially if you stand up quickly or have been in the heat for a long time.
5. Worsening of Chronic Conditions
People with chronic illnesses—like diabetes, heart disease, or respiratory conditions—are more vulnerable during heat waves. For example, extreme heat increases the risk of hospital admission for people with diabetes by 4.5%, and by 10% for older adults with diabetes.

6. Mental Health and Mood
Heat doesn’t just impact your body—it can also affect your mind. High temperatures are linked to increased irritability, mood changes, confusion, and even mental health crises, especially in vulnerable populations.
Practical Planning Tips for Beating the Heat
1. Plan Ahead for Hot Days
- Check the weather forecast and plan outdoor activities for the coolest parts of the day—usually early morning or late evening.
- Reschedule non-essential outings if possible during extreme heat.
- Prepare a heat safety kit: water bottles, electrolyte drinks, sunscreen, hats, and lightweight clothing.
- Identify air-conditioned places nearby (libraries, shopping centers, community centers) where you can cool off if needed.
2. Keep Your Home Cool
- Use air conditioning if available. If not, use fans and keep windows open when it’s cooler outside than inside.
- Block out sunlight with curtains or blinds during the hottest part of the day.
- Seal gaps around doors and windows to keep cool air in and hot air out.
- Take cool showers or use a damp towel to lower your body temperature.
3. Stay Hydrated
- Drink water regularly—even if you don’t feel thirsty. Aim for a cup every 15-20 minutes when active outdoors.
- Avoid drinks that dehydrate, like caffeine and alcohol.
- Carry a reusable water bottle everywhere you go.
- If you have a medical condition that limits fluid intake, ask your doctor how much to drink during hot weather.
4. Dress for the Heat
- Wear lightweight, light-colored, loose-fitting clothes.
- Protect your skin with sunscreen (SPF 15 or higher) and reapply every two hours.
- Wear a wide-brimmed hat and sunglasses outdoors.
5. Protect Vulnerable Loved Ones
- Check on seniors, children, and anyone with chronic health conditions regularly during heat waves.
- Never leave children, elderly people, or pets in parked cars—even for a minute. Temperatures inside can rise dangerously fast.
- Help neighbors who may not have air conditioning or easy access to cool spaces.

Heat and Relationships: Staying Connected and Supportive
Heat and Relationships: Staying Connected and SupportiveHigh heat can strain relationships—especially when everyone feels uncomfortable or irritable. Here’s how to keep your connections strong:
- Communicate openly about heat-related plans and concerns, especially if you live with others or care for vulnerable family members.
- Share cooling resources—like fans or air-conditioned spaces—if someone you know is struggling.
- Plan indoor activities together, such as movie nights, board games, or cooking cool meals.
- Encourage hydration and remind each other to take breaks from the sun.
- Be patient—heat can make everyone a little more irritable or tired than usual.
Heat Safety at Work and Outdoors
If your job or hobbies keep you outdoors, take extra precautions:
- Take frequent breaks in the shade or indoors.
- Drink water regularly and avoid heavy meals during the hottest hours.
- Wear protective clothing and use sunscreen.
- Know the signs of heat-related illness and act quickly if symptoms appear.

First Aid for Heat-Related Illnesses
If you or someone you know shows signs of heat exhaustion or heat stroke:
- Move to a cool, shaded area immediately.
- Loosen or remove heavy clothing.
- Provide cool water to sip slowly.
- Fan and mist the person with water, or apply cool, damp cloths.
- Call emergency services if symptoms are severe or do not improve quickly.
Special Considerations: Children, Seniors, and Pets
- Children can overheat quickly. Dress them in light clothing, keep them hydrated, and never leave them in cars.
- Seniors may not feel thirsty until they’re already dehydrated. Check in often and help them stay cool and hydrated.
- Pets need shade, water, and never to be left in vehicles or hot spaces.
Making Heat Safety a Community Priority
Extreme heat is a growing public health challenge, but together, we can reduce risks. Share heat safety information with your community, support vulnerable neighbors, and advocate for cooling centers and resources in your area.
