How to stay warm camping
A warm night depends on a complete sleep system: a dry sleeper, an appropriately rated sleeping bag, and an insulated pad between the sleeper and the ground.
A thick sleeping bag cannot replace an insulated pad. Check the forecast low at the actual campground, keep sleep clothing dry, eat adequately, and change the plan if the system does not match the conditions.
Cold-night readiness check
The four parts of a warmer night
- Ground insulation: use a pad intended to reduce heat loss into the ground.
- Bag rating: compare a standardized comfort-oriented rating with the expected campsite low.
- Dry layers: change out of clothing dampened by rain or sweat before bed.
- Weather margin: allow for a colder campsite, wind, moisture, and personal differences.
Know the warning signs. Shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech, and drowsiness can indicate hypothermia. Hypothermia is a medical emergency; follow CDC guidance and seek emergency help.
