Staying Warm in the Wilderness
Layering always works: The best way to combat cold is not to allow it to escape from your body. Make sure that you are wearing as many layers as you can.
Empty your bladder to stay warm: Now, it may sound crazy, but it is true. When your body stores urine, it needs extra heat to keep that liquid warm. If you empty your bladder, that energy can be used to keep your other body parts warm.
Get cozy with your partner: If you are with someone in the wild, cuddling up while sleeping can be helpful.
Cover your head: Most amount of body heat is lost through your head. Make sure that you insulate your head correctly. Wear a hat or something.
