(Oh, yes you can!)

Sleeping systems don't heat themselves. They only slow the escape of your own body heat.

The Bed:



  • Get warm before you climb into your bag.
  • Just before bed try jumping jacks or running in place to warm up.
  • Try muscle-tensing exercising inside the bag to generate warmth.
  • A small amount of gorp eaten shortly before bed stoke your body's furnace well.
  • Keep a small amount of gorp nearby to help out if you wake at night.
  • Keep yourself well hydrated but don't drink right before bedtime.
  • Don't forget caffeine is a diuretic.
  • Always go for a pee before crawling into bed.
