A strong heat wave can make people sick fast. This guide explains in simple words: why heat waves happen, who is at risk, early signs of heat illness, what to do right away, and easy steps to stay safe in Los Angeles or any hot city. Use this as public health advice — not a full medical exam. If someone shows severe signs (confusion, fainting, very high body temperature), call 911 immediately.

Why heat waves are a big problem now

Heat waves are becoming more frequent and longer in many places. This means more hot days, and more people can get sick from heat. Warmer months in 2024–2025 were above normal in many parts of the US, making heat a bigger public health risk.

Is Los Angeles at risk?

Yes. Los Angeles and Southern California often face very hot inland temperatures and warm coastal nights. County health officials issue heat advisories and warnings when high heat threatens people — watch local updates and city alerts.

Who is most at risk?

• Older adults (over 65)
• Young children and babies
• People with heart disease, lung disease, diabetes, or kidney problems
• People who take certain medicines (diuretics, some heart or psychiatric drugs)
• People who work outdoors (construction, delivery, farming)
• People without good cooling at home (no AC or poor shelter)

Common heat illnesses — signs to watch

• Heat cramps: painful muscle spasms while active in the heat.
• Heat exhaustion: heavy sweating, weakness, dizziness, headache, nausea. Person may be cool and pale.
• Heat stroke (emergency): confusion, fainting, seizure, no sweating, hot dry skin, very high body temperature. Call 911 now.

If you suspect heat exhaustion, move the person to a cool place, give water, and cool them with wet cloths. Heat stroke needs emergency care.

Immediate steps if someone is very hot or faint

1. Move them out of the sun to shade or an air-conditioned place.
2. Remove extra clothing. Fan them and apply cool, wet cloths.
3. Give sips of water if they are awake and able to drink.
4. If confusion, loss of consciousness, or seizures occur — call 911 right away.

Simple prevention tips you can use every day

• Stay in air-conditioned places when heat is high. If you don’t have AC at home, use public cooling centers, malls, or libraries.
• Drink water often — even before you feel thirsty. Avoid heavy alcohol or very sugary drinks in hot weather.
• Wear light, loose, and light-colored clothes. Use a hat and sunglasses.
• Do physical work early in the morning or late in the evening, not during peak heat (usually midday to late afternoon).
• Use shade, fans, and cool showers to lower body temperature.
• Check on neighbors, older adults, and people with health problems. Use the buddy system during heat waves.

Advice for outdoor workers and employers

• Provide shaded rest areas and water near work zones.
• Rotate workers and schedule heavy tasks during cooler hours.
• Train staff to recognize early heat illness and respond quickly.
• Have emergency plans and first-aid ready on site.

Tips for pet safety

• Never leave pets in a closed car — temperatures rise fast.
• Provide fresh water and shaded rest. Limit heavy exercise midday.
• If an animal shows trouble breathing, collapse, or vomiting — call a vet immediately.

Where to find cooling help in Los Angeles

When the county issues heat advisories, the Los Angeles County Health Department posts locations of cooling centers and public help. Check local city pages and LA County Public Health for the latest list.

A few easy home changes that help a lot

• Close curtains during the day and open windows at night to let cool air in.
• Use fans plus cool showers — fans help evaporate sweat and feel cooler.
• Eat light meals; heavy meals raise body temperature.
• Put ice or frozen water bottles near fans for extra cooling.
