It’s no fun to wake up shivering while you’re in the woods. It’s supposed to be when you are warm and cozy in your tent, recharging for adventures for the next day. We’ve got a few tips that will help you stay warm at night.

1. Use a hot water bottle

One of the easiest ways to stay warm in any season is to take a hot water bottle into your sleeping bag. Just fill up your hard plastic water bottle with hot water and place it between your legs when you’re in your sleeping bag. If it’s too hot, wrap a piece of clothing around it first.

2. Use the bathroom

Did you know that when your bladder is full, your body is keeping that liquid warm? If you empty it out, your body needs less energy to stay warm and toasty. Too cold to pee outside? Try a collapsible pee bottle (and women can use a pee funnel to pee into the bottle).

3. Eat!

You probably don’t need a reason to nibble on something tasty, but you have a good reason to now. If you wake up cold, eat a candy bar to get your metabolism up and running. This will keep you warmer as you head back to sleep.

4. Pick the right sleeping bag

Picking the right sleeping bag makes nights out so much better. You’ll want a sleeping bag rated to a temperature below the temperature of the coldest night you’re planning on sleeping in. If you run a little cold, you’ll want to choose a bag that’s rated even lower. Also, if you’re a woman, think about getting a women’s specific sleeping bag. They really do help.

5. Pick the right sleeping pad

Sleeping pads make a huge difference too. They insulate you from the cold ground below you. Choose one that’s rated to the right temperature, and you’ll have a much better time outdoors. Some people even bring two sleeping bags-one foam and one inflatable-and that can help too. If you’re in a pinch, put some gear or clothes under your sleeping pad to add some insulation.

6. Light a fire

Obvious, but true, lighting a campfire (where permitted) is a great way to stay warm whilst camping. Before you head to your camp, read up on the rules that the land manager has for the area in which you’ll be staying. If campfires are permitted, bring some wood along with you on your trip. That way you’ll be ready to light a flame when temperatures start dropping.
