Being cold at night is the number one reason people give up on camping. It’s almost always fixable. Here are nine proven ways to stay warm in a tent.
1. Insulate from the ground first
Most heat is lost into the cold ground, not the air. A sleeping pad with a good R-value matters more than a warmer bag — double up a foam pad under an inflatable one in cold conditions.
2. Match your bag to the temperature
Check the bag’s comfort rating, not its extreme rating, and add a liner for extra warmth. See our sleeping bag picks.
3. Layer smart — but don’t overdo it
Dry base layers and a hat trap heat; too many bulky layers compress the bag’s insulation and make you colder. Keep a dedicated dry set of sleep clothes.
4. Eat and hydrate before bed
Your body needs fuel to generate heat. A warm drink and a small fatty snack before sleeping genuinely helps.
5. The hot-water-bottle trick
Fill a leakproof bottle with hot water and tuck it near your core or feet inside the bag — a classic for a reason.
6. Vent to fight condensation
Crack a vent to let moisture escape; a damp bag is a cold bag.
7. Cover your head and neck
A beanie and a buff dramatically cut heat loss from your head and neck.
8. Warm up before you get in
Do a few jumping jacks to get blood flowing, then climb into the bag already warm rather than waiting to warm a cold bag.
9. Pick a sheltered pitch
Camp out of the wind and off low, cold hollows where cold air pools. A good tent and site do half the work.
