How to keep warm in winter outdoor camping

Don't drink too much water before bed

Not only is it painful to climb out of the tent to go to the toilet in the middle of the night, but also because the body stores urine in the bladder and maintains it at a temperature slightly higher than body temperature, which requires more body heat. So in order not to get up in the middle of the night to pee or hold back, remember not to drink too much water before going to bed, or to get into your tent and sleeping bag after confirming that it has been eliminated.

Eat as many calories as possible before bed

Calories are the fuel that generates heat in the body. Without fuel, the boiler of the body cannot burn efficiently. If you don’t want to eat too much, or have a bad appetite, you can prepare some high-calorie snacks or action food. If you feel cold in the middle of sleep, you can add calories and let your body continue to function.
do a little warm-up
Think of your sleeping bag as a thermos, with hot water to keep it warm and cold water to keep it iced. So before going into the sleeping bag, do a little jumping or squatting, any simple warm-up exercise that won't cause an extra burden.
And as a rule of thumb, filling up an inflatable sleeping pad before going to bed is a great warm-up exercise….

get your sleeping bag

The quickest way is to invest in a warm down sleeping bag. You get what you pay for, comparing the comfortable temperature and the extreme temperature of the sleeping bag, and choosing the body length that suits you is the choice condition for a good night’s sleep.
Reminder! The "extreme temperature" marked on the sleeping bag is usually for reference only, because the body temperature and humidity have to be taken into account. But the warmer the sleeping bag, the heavier it must be. "Lightweight" and "warm" are not the best of both worlds.

But if your existing sleeping bag isn't warm enough, there are ways to overcome it.
1. Purchase the inner sleeve of the sleeping bag to increase the warmth and keep the down sleeping bag clean.
2. Or put hot water in a kettle and throw it into a sleeping bag to warm it up, which is also a method, but remember not to use a thermos for hot water.
3. Don't burrow in as soon as you open the sleeping bag, let it sit for a while, and after the air in the down compartment is full and inflated, the sleeping bag will have a better temperature isolation effect.
4. The opening zipper of the sleeping bag is divided into left and right sides. If you buy zippers of the same style and different directions with your partner, you can combine two single sleeping bags into a double sleeping bag! With the blessing of body temperature, a good night's sleep is guaranteed! But only if you find a partner.

Body temperature is a good thing, don't resist it....

Precautions when sleeping
1. Remember to wear a wool hat to keep warm, don't cover your nose and mouth with a sleeping bag, and use a breathable magic head scarf instead. Because the warm air exhaled from the nose and mouth will dampen the sleeping bag, thus reducing the thermal function.
2. Keep your feet and socks dry, put on a thick layer of spare socks if necessary, or even empty your backpack and stuff your feet in. Another method is to stick the soles of the feet to warm the baby, and then put on a layer of wool socks, the effect is also very good! The older generation often said, "If your feet are hot, you won't be cold." This is the truth.
Put it in the sleeping bag first, then put it in the backpack.
3. Use a sleeping pad to isolate the contact between the back and the ground. Because most of the cold air rises from the ground, the thicker the bottom of the tent, the better the warmth retention effect. Backpack covers, garbage bags.... all on the bottom! (In the camp with plants, you can also lay a lot of leaves and grass under the ground cloth first)
Using a raised camp bed seems to be the most effective isolation from the ground, but even a lightweight camp bed weighs three times as much as a typical lightweight sleeping pad.
4. Make sure the inside and outside of the tent are ventilated, even if it's cold outside! Poorly designed tents, because they cannot be ventilated, the temperature difference between the inside and outside will be too large, which will cause the internal moisture to condense and cause moisture or frost.

Choose your camp carefully
This is a decision that must be made before camping. Judging the wind direction of the camp, the moisture of the soil on the ground, the range of sunshine after dawn, etc., can all affect the temperature and comfort after going to bed that night.
If you are camping in a place where shelter from the wind is not possible, use the canopy to build a barrier next to your tent!
