Staying warm while camping comes down to three things: keeping your body heat in, keeping cold ground and wind away from you, and giving your body fuel to produce heat. Follow the steps below and you will sleep warmer, wake up with fewer aches, and spend less time shivering through a cold night. These tips for staying warm camping work for tents, car camping and shoulder-season trips alike.

Start With Your Clothing Layers

Dress in three layers: a moisture-wicking base layer, an insulating middle layer such as fleece or down, and a windproof, water-resistant outer shell. Cotton holds sweat and loses almost all of its insulating value when damp, so leave it at home. Bring a dedicated set of dry sleeping clothes, including a warm hat, and change into them only when you get into your bag. Sweating during the day and then sleeping in damp layers is one of the fastest ways to get chilled.

Build a Warm Sleep System

Your sleeping bag is only part of the equation. Check the temperature rating on the bag and plan for about 10 to 15 degrees Fahrenheit colder than the forecast low, since manufacturers’ comfort ratings often assume a dry, still night. Put a closed-cell foam pad or a pad with an R-value of 4 or higher under your bag, because the ground pulls heat out of your body faster than cold air does. Use a liner, such as a fleece or silk bag liner, to add a few degrees of warmth and keep your bag cleaner.

Set Up Your Shelter for Heat Retention

Pitch your tent on the most sheltered flat spot you can find, away from low ground where cold air settles. Keep the vestibule closed at night, but make sure there is still some ventilation to limit condensation from your breath. Store wet gear and boots outside the tent or in the vestibule so moisture does not build up inside. A tent that stays dry is noticeably warmer than one that is damp.

Warm-Up Checklist Before Bed

  1. Eat a high-fat, high-calorie snack, such as nuts, cheese or a bar.
  2. Drink a warm, non-alcoholic beverage, and empty your bladder before you get in your bag.
  3. Put on dry sleeping layers and a hat.
  4. Place a water bottle filled with hot water inside your bag at your core or feet, using a sealed bottle.
  5. Stash your headlamp, phone and water within reach so you do not have to leave the bag in the cold.

Fuel Your Body and Stay Active

Your body produces heat by burning food, so eat a substantial meal at dinner and keep high-energy snacks handy overnight. Hot drinks help, but the calories matter more than the temperature. Do some light activity, such as jumping jacks or a short walk, before you get in your bag to raise your core temperature. Avoid alcohol before bed, since it dilates blood vessels and makes you lose heat faster. Early signs of hypothermia include uncontrollable shivering, slurred speech and clumsy hands; if you notice these, warm up immediately and consult a professional or seek medical help if symptoms do not improve.

Common Mistakes to Avoid

  • Sleeping in the same clothes you wore all day, which are often sweaty and cold.
  • Skipping a sleeping pad and relying on the bag alone.
  • Letting your breath condense into frost inside the tent by sealing it up completely.
  • Going to bed hungry or dehydrated.
  • Bringing a bag rated only for the average nighttime low instead of the cold you expect.

A closed-cell foam sleeping pad adds insulation without adding much weight, and it works well as a backup even if you use an inflatable pad. A fleece or silk liner adds a few degrees of warmth and keeps your sleeping bag cleaner between trips. A wide-mouth insulated bottle lets you fill it with hot water for your sleeping bag, and it is safer to store than a standard plastic bottle. View on Amazon View on Amazon View on Amazon

FAQ

What temperature rating should my sleeping bag have?

Choose a bag rated at least 10 to 15 degrees Fahrenheit below the coldest night you expect. Comfort ratings are often more useful than the lower limit, since the lower limit is usually a survival rating.

Does a hot water bottle really help?

Yes. A sealed bottle of hot water placed near your core or feet adds warmth for an hour or more. Make sure the bottle is leak-proof and rated for hot liquids.

Should I sleep with my hat on?

Yes. A significant share of body heat escapes through your head and neck, so a dry hat makes a noticeable difference. Keep it dry and change into a fresh one if the first gets damp.

Conclusion

Warm camping comes down to dry layers, a good sleep system, a sheltered campsite and enough food in your body. Work through the checklist before bed and you will wake up rested instead of shivering. Practice these habits on a cool-weather trip close to home before you head into real cold.
