To rest, make use of a water bottle
The most basic method to camp is to boil a cup of water over your campfire and then pour the hot water into a small, rubber water bottle. Put the bottle inside your sleeping bag prior to when you go to the bed. The bottle will feel warm and comfortable when you finally get up.
Keep your batteries charged
Batteries can be particularly damaged by cold weather, so it is essential to charge them when camping. Store your camping equipment in your sleeping bag until you head to bed at night. It will make sure that your batteries aren't drained of their charge.
