3. Smoke Yourself with Campfire
A campfire can provide you with much more than just warmth and the ability to cook your food. In a pinch, sitting close to the fire will allow you to take advantage of the anti-microbial benefits of smoke.
You can also lay your clothing near the fire to help freshen it up a bit. This will not remove a lot of grime from your body or clothing, but you will feel cleaner after exposure to smoke.
Make sure you do not sit closely enough to inhale a lot of smoke, though, because this can cause irritation to your lungs and eyes.
