Here are some handy tips for staying warm while camping in cool temperatures: Exercise before bed to warm up your body. Set up a well-insulated tent, sleeping pad, and sleeping bag. Change into warm, insulating pajamas before going to bed. Cover your feet with warm socks and wear a hat while sleeping. Keep a thermos or insulated container of tea or hot cocoa in the tent for quick warmth if the temperature drops. Have a first aid kit with a spare blanket and a thermometer nearby in case someone's core body temperature drops, indicating hypothermia. If this happens, seek immediate warming and medical help.
