Recognizing and preventing hypothermia at camp

How hypothermia happens on camping trips, even in cool rather than freezing weather: the early warning signs to watch for in yourself and others, how to stay warm and dry, what to do while you get help, and how to protect kids and older campers.

Why hypothermia matters for campers

Hypothermia happens when your body loses heat faster than it can produce it, and your core temperature drops too low. The CDC describes it as an abnormally low body temperature, below 95°F. It is often linked with winter, but campers can get into trouble in much milder weather. The CDC notes that hypothermia can occur even at cool temperatures above 40°F if a person becomes chilled from rain, sweat or being in cold water. A wet, windy shoulder-season evening is a classic setting.

The good news is that hypothermia is largely preventable with the right clothing, food, shelter and habits, and early signs are easy to spot if you know what to look for. This guide covers the basics. It is general information, not medical training. If you camp in cold or remote places, a wilderness first aid course is a worthwhile investment.

How campers lose heat

Your body loses heat in several ways, and camping exposes you to all of them:

Wet clothing. Water pulls heat away from the body much faster than air. Rain, sweat, snow and wet grass all count.
Wind. Moving air strips away the warm layer next to your skin, which is why a breezy evening feels colder than the thermometer suggests.
Contact with cold ground. Sitting or sleeping on cold ground without insulation draws heat away. This is why sleeping pad R-values matter. See sleeping pad R-values.
Exhaustion and hunger. A tired, underfed body produces less heat.

Hypothermia often builds slowly. A hiker sweats on the climb, stops in the wind at a viewpoint, gets chilled, then arrives at camp tired and damp as the temperature drops.

Know the warning signs

The CDC lists these warning signs of hypothermia in adults:

Shivering
Exhaustion or feeling very tired
Confusion
Fumbling hands
Memory loss
Slurred speech
Drowsiness

In infants, the CDC lists bright red, cold skin and very low energy. Some outdoor educators sum up the early stage as the "umbles": someone who stumbles, mumbles, fumbles and grumbles more than usual.

A person who is getting hypothermic often does not notice it themselves, because confusion and poor judgment are part of the condition. That makes it a group responsibility. Check on each other, especially in wet or windy weather. If someone stops shivering but still seems cold and confused, that can be a sign that things are getting worse, not better.

Prevention: stay dry, stay fueled, stay insulated

Dress in layers. A base layer that wicks moisture, an insulating layer such as fleece or a puffy jacket and a wind and rain shell let you adjust as conditions change. Avoid cotton as a base layer in cool, wet weather, because it stays wet and cold. See layering for camping.

Manage sweat. Take off a layer before a climb and put it back on when you stop. Arriving at camp soaked in sweat is a common start to getting chilled.

Keep rain gear handy. Put on rain gear early, before you are wet, not after. See rain gear for camping.

Change into dry clothes at camp. Keep a dry set of base layers and socks in a waterproof bag for camp and sleep only.

Eat and drink regularly. Food is fuel for heat. Snacks during the day, a warm dinner and a warm drink before bed all help. Staying hydrated matters in cold weather too.

Insulate from the ground. Use a pad suited to the season and sit on a foam pad rather than on cold rock or snow.

Cover your head, hands and neck. A warm hat, gloves and a neck gaiter are small, light and make a noticeable difference. See glove and mitten layering for cold camps.

Plan for the night. Choose a sleeping bag rated for the conditions and know how to add layers. Our guides to sleeping bag temperature ratings and sleep system layering for variable nights explain how.

Weather and planning

Check the forecast for temperature, wind and rain, and remember that it is often colder at higher elevations and near water. Plan shorter days in cold, wet weather and arrive at camp with daylight and energy left. Shoulder-season trips deserve extra margin; see our shoulder-season camping checklist. If the weather turns worse than expected, it is fine to cut a trip short or retreat to the car.

What to do if you suspect hypothermia

The CDC advises that if a person's temperature is below 95°F, it is an emergency, and you should get medical attention immediately. In the outdoors, call 911 or emergency services if you have a signal, or send for help. While you wait, the CDC's general first aid steps are:

Get the person into a warm shelter, such as a tent, vehicle or building, if possible.
Remove any wet clothing.
Warm the center of the body first: chest, neck, head and groin. Use dry blankets, sleeping bags, clothing or skin-to-skin contact under loose, dry layers.
Warm beverages can help raise body temperature, but do not give alcoholic drinks, and do not try to give drinks to an unconscious person.
After body temperature has increased, keep the person dry and wrapped in a warm blanket, including the head and neck.

Handle the person gently. A person with severe hypothermia may seem to have no pulse or breathing; the CDC advises giving CPR if trained, and continuing while the body is warmed until help arrives. Seek medical care even if the person seems to recover.

Kids, older campers and pets

Children lose heat quickly and may not tell you they are cold, so check their hands, feet and mood often. Keep spare layers and dry socks for kids within easy reach. Older adults may also feel the cold less or lose heat faster, and some medications and health conditions affect temperature regulation, so talk to a doctor before a cold-weather trip if you have concerns. Dogs can get cold too, especially small and short-coated breeds; see camping with dogs gear.

A cold-weather hypothermia kit

Spare dry base layers, socks, hat and gloves in a waterproof bag
A warm insulated jacket for camp
Rain jacket and pants
An emergency blanket or bivy
A stove and pot for warm drinks
High-energy snacks
A sleeping bag and pad rated for the conditions

Keep emergency items with your camp first-aid kit basics.

Bottom line

Hypothermia can happen well above freezing when wind, rain and fatigue combine. Stay dry, eat and drink regularly, insulate from the ground, change into dry clothes at camp and watch your group for shivering, fumbling and confusion. If someone shows signs of hypothermia, warm them gently and get medical help.
