Extreme heat is one of the deadliest weather threats in the United States — and for our unhoused neighbors, it’s the most dangerous season of the year. When temperatures spike, people experiencing homelessness face heat around the clock with no air conditioning to retreat to, limited access to drinking water, and pavement that radiates heat long after sundown. The result: dehydration, heat exhaustion, and heatstroke arrive faster and hit harder than they do for anyone else in the city.
We’ve written before about how winter weather affects people experiencing homelessness in LA — but Southern California’s brutal summers are the other half of that story, and in many ways the more dangerous half. Here’s what extreme heat does to people living outside, how to recognize when someone is in danger, and how The Midnight Mission — and you — can help.
Why Extreme Heat Is So Dangerous for People Experiencing Homelessness
For most Angelenos, a heatwave means higher electric bills. For the thousands of people experiencing homelessness in Los Angeles, it means an emergency with no exit:
No escape from the sun. Housed residents pass a heatwave in air conditioning; a person living outside may spend 12 or more hours a day in direct sun with nowhere shaded to rest.
The pavement itself becomes a hazard. Downtown’s concrete and asphalt absorb heat all day and radiate it all night — the “urban heat island” effect means Skid Row often stays dangerously hot long after sunset, robbing the body of the overnight recovery it needs.
Water is hard to come by. Staying hydrated in extreme heat requires steady access to clean drinking water — something most of us never think about, and something a person on the street may spend hours trying to find.
Health conditions compound the risk. Chronic illness, heart and respiratory conditions, and some common medications all impair the body’s ability to regulate temperature. Because preventive care is hard to access without housing, many people enter the summer already medically vulnerable.
Sun exposure adds up. Severe sunburn, blistered skin, and eye damage from day-after-day exposure are painful on their own — and they further reduce the body’s ability to cool itself.
The bottom line: heat illness isn’t a possibility for people living outside during an LA heatwave — it’s a daily threat that compounds with every hot day in a row.
The Health Risks: Dehydration, Heat Exhaustion, and Heatstroke
Dehydration
Dehydration is where heat illness begins. In triple-digit temperatures, the body can lose fluids faster than they can be replaced — causing headaches, dizziness, confusion, and rapid heartbeat. For someone without reliable access to water, mild dehydration in the morning can become a medical emergency by afternoon.
Heat Exhaustion
Heat exhaustion is the body’s warning siren: heavy sweating, weakness, nausea, clammy skin, and a fast, weak pulse. Caught early — with shade, water, and rest — it’s reversible. Ignored, it escalates.
Heatstroke
Heatstroke is a life-threatening emergency. The body’s cooling system fails entirely, core temperature climbs to 103°F or beyond, and confusion, slurred speech, or loss of consciousness follow. Without immediate treatment, heatstroke causes permanent organ damage or death. It’s the reason heat ranks among the deadliest weather events in America — and people living outside are among its most frequent victims.
Heat Exhaustion vs. Heatstroke: How to Tell the Difference
| Heat Exhaustion | Heatstroke (Call 911) | |
| Skin | Heavy sweating; cool, pale, clammy | Hot, red; may be dry or damp |
| Behavior | Tired, weak, dizzy, nauseous | Confused, slurred speech, agitated, or unconscious |
| Body temperature | Elevated but below ~103°F | 103°F or higher |
| What to do | Move to shade, sip water, cool with wet cloths | Call 911 immediately — cool the person while waiting; do not give fluids if unconscious |
If you see someone on the street showing signs of heatstroke — confusion, hot skin, unresponsiveness — call 911 immediately. It is always the right call. While you wait, help them to shade and cool them however you can.

Frequently Asked Questions: Heat and Homelessness
What temperature is dangerous for people living outside?
Risk rises sharply once temperatures pass the low 90s, especially across consecutive days — but there’s no single safe cutoff. Humidity, direct sun, radiating pavement, and lack of overnight cooling can make even mid-80s conditions hazardous for someone exposed all day with limited water.
What’s the difference between heat exhaustion and heatstroke?
Heat exhaustion is the warning stage — heavy sweating, weakness, nausea, clammy skin — and can be treated with shade, water, and rest. Heatstroke is a medical emergency: the body stops cooling itself, temperature exceeds 103°F, and confusion or unconsciousness sets in. Heatstroke requires calling 911 immediately.
Where can people experiencing homelessness get water and cooling in Los Angeles?
The Midnight Mission on Skid Row provides water, meals three times daily, showers, and shaded respite year-round, with no requirements to walk in. During declared heat emergencies, the City and County of LA also open cooling centers — but for many on Skid Row, the Mission is the nearest and most consistent relief.
How can I help unhoused people during a heatwave?
Donate bottled water, sunscreen, and hygiene supplies; volunteer at meal services; check on unhoused neighbors and offer water; and call 911 if someone shows signs of heatstroke. Financial donations help relief organizations respond fastest when heat emergencies hit.
Should I call 911 if I see someone unresponsive in the heat?
Yes — immediately. Confusion, hot skin, or unresponsiveness during hot weather are signs of heatstroke, which can be fatal within hours. Calling 911 is always the right decision; while you wait, help the person into shade and cool them with water on their skin and clothing.
