Stuttgart - Outdoor enthusiasts should always have a meal before sleeping in the great outdoors, according to the Stuttgart- based magazine Outdoors.

A camper's body turns the extra food into fuel to help stay warm during the night. Pre-camping meals should be warm and easy to digest.

Campers who do not eat special meals can make do with an energy bar and a hot tea. If you find you're already freezing before you even get into the sleeping bag, it's best to get your circulation going by walking vigorously around the tent or doing push-ups or knee bends. (dpa)
