Head into the mountains in summer, or almost anywhere in fall or spring, and you can encounter nighttime and morning temperatures anywhere from the 40s Fahrenheit to below freezing. I’ve spent enough frosty nights outside over the past few decades to learn a few things about how to stay warm. (My coldest night was -30° F, in winter in New Hampshire’s White Mountains; I don’t recommend it.) Here are my 10 tips for making your camping experience more comfortable.

1.    At the end of each hiking day, wash the dried sweat from your body; it can act like a heat conductor, chilling you.

    So I have a crazy-pants tip to add to the list I swear had worked for me: No matter how cold and uncomfortable it is outside, make sure to completely empty your bladder before going to sleep. If you need to go in the middle of the night, do it. Don’t hold off until morning.

    My pseudo-science theory as to why this seems to work: instead of your body working hard to keep all that pee at a toasty 98 degrees, it can use that energy to keep the rest of your bits warm.

    Take it or leave it . But I’ve decided a few seconds of cold booty is worth hours of greater warmth in my bag.

      Thanks, Jes. I first heard that tip years ago. I’ve debated it with friends who have science backgrounds and insist that the body would not burn any more energy heating urine that’s inside the body that’s at body temperature, anyway. My take is that staying well hydrated certainly helps keep you warm, and I relieve myself right before bed in hopes of not having to get up during the night; but if I have to, I do get up, because it’s hard to sleep otherwise. Keep a warm puffy jacket handy to slip on if you have to get up.

    Some really great tips – thanks so much! I’m a cold sleeper and staying warm in the night is always one of my main points of focus.

    Thanks for the great tips, will definitely help with my kids when camping in the mountains were it gets quite cold at night.

    I use Coleman Trinidad warm weather sleeping bag (http://campingandcamping.com/coleman-trinidad-sunridge-warm-weather-sleeping-bag-review/) for my summer camping trips.

    For colder weather I have two more sleeping bags. One is a 3-season sleeping bag, another one is a 4-season sleeping bag.

    There is definitely no need to spend 300 or 500 USD for a summer sleeping bag. Don’t get fooled by the “amazing features”. A warm weather sleeping bag can be as simple as it can be…

    i would add to store fuel and batteries in your bag so you can use them the next day

    I wouldn’t get sleeping bags for kids that young. Check out the answer I gave a reader to that question: https://thebigoutside.com/ask-me-tips-on-sleeping-bags-for-backpacking-with-a-4-year-old-and-for-her-parents/.

    I usually don’t have much of a problem staying warm since I use a nice down bag, but our kids, 4 months and 2.5 years get cold. We usually try to have them sleep near mom and haven’t stepped out to get them their own little bags yet.

    This is something I always struggle with. Thanks for the tips!
