Short version: Los Angeles sees strong heat waves in 2025. Heat can be dangerous — especially for children, older adults, outdoor workers, and people with health problems. This guide explains simple signs, what to do right away, and how to prevent heat illness at home and work.

Why this matters now: Southern California had major heat events this season — high daytime heat and warm nights make it hard to cool down. If someone is confused, fainting, or not sweating, act fast — these are signs of heat stroke.

What is a heat wave and who is at risk?

A heat wave is several hot days in a row — often with warm nights. People most at risk:

• Older adults (65+)
• Babies and young children
• People with heart, lung, kidney, or other chronic illnesses
• People on certain medicines (water pills, some blood pressure or mental health drugs)
• Outdoor workers, athletes, and people without cool homes

Common heat illnesses — simple signs to watch

• Heat cramps: painful muscle cramps (legs, stomach).
• Heat exhaustion: heavy sweating, weakness, cold/clammy skin, fast pulse, headache, dizziness, nausea or fainting.
• Heat stroke (emergency): high body temp, red/dry or very sweaty skin, confusion, loss of consciousness, seizures — call emergency services right away.

Immediate steps if someone looks sick from heat

1. Move them to a cool place (shade, air-conditioned room or car with AC).
2. Cool the person: remove excess clothes, apply cool wet cloths or spray water, fan them.
3. Give sips of water if they are awake and can swallow (not for someone who is confused or vomiting).
4. If very hot, confused, not sweating, or fainted — call 911 immediately (possible heat stroke).

How to stay safe at home — easy practical tips

• Keep windows closed during hottest hours and use AC or fans. If you don’t have AC, go to a cool public place or cooling center for a few hours.
• Hydrate often — small, regular sips of water. Avoid very sugary drinks and limit alcohol and caffeine.
• Wear light, loose clothing and a wide hat outside. Use sunscreen. Avoid heavy exercise in the heat of the day.
• Take cool showers or wet cloths to lower body temperature. Sleep where it feels coolest — low floors, shades drawn at day, open windows at night when it cools.
• Keep a simple “heat kit”: water bottle, electrolyte drink (if needed), cooling towel, list of emergency numbers, and medicine list for older family members.

Advice for outdoor workers and athletes

• Work earlier or later when it is cooler. Take frequent rest breaks in shade or AC.
• Use paced work, buddy checks (watch each other), and drink water every 15–20 minutes.
• Employers: plan heat breaks, reduce heavy tasks on the hottest days, and inform workers about signs of heat illness.

Special tips for parents and carers

• Never leave a child or pet alone in a parked car — temperatures rise fast.
• Dress infants in light layers and keep them in shade. Keep extra water for older kids.
• Check on elderly neighbours and family members at least twice a day during heat events.

Heat and long-term health — what to watch for

If you have heart disease, lung disease, kidney problems, or take medicines for blood pressure or mental health, talk to your doctor about how heat may affect your treatment. Make a simple Heat Action Plan with your clinic if you are at high risk.

Quick checklist — what to do today

• Check local heat alerts and weather for your area.
• Keep a full water bottle and refill often.
• Make a plan for cool time each day (library, mall, community cooling center).
• Make a phone list: family, neighbours, doctor, emergency services.

When to see a doctor or call emergency

Call 911 if the person is unconscious, confused, has a seizure, or has very high body temperature and is not cooling. See a doctor if heat symptoms last or if you have a chronic condition and feel worse during heat waves.

Final words — quick safety reminder

Heat is simple to prevent with a few small steps: check alerts, drink water, cool the body, and watch older people and kids closely. For local updates and cooling center locations check city and county health pages.
