Includes ideas on sun protection, using padding stay insulated from the ground, the use of chemical heat packs, and more.
During the winter months, sunlight can be particularly intense. Ultraviolet radiation is reflected by snow, which can burn skin and cause snow blindness in the eyes. Wear a pair of sunglasses that is certified to protect 100% of UV rays. Some pairs of glasses have leather flaps, to keep sunlight from entering in from the sides. A sun block lotion with a high SPF will protect exposed skin, and should be applied regularly during the day to the nose, cheeks, ears, and the back of the neck.
At night, a hot water bottle can add more heat to stay warm in the sleeping bag. Heat up some water in a pot on the camp stove, and pour into a thick, plastic water bottle, preferably one with a wide mouth for ease in pouring. Wrap the bottle with cloth, such as an extra shirt or sock, so that the hot surface does not burn the skin. Keep it close to the body until it is time for bed. Then, place the bottle where it will best provide heat, such as between the legs, or held close to the chest. In the morning, the water will still be liquid, providing that first quart of water for the day. Use a powdered drink mix to mask the taste of the boiled water.
Without a full length sleeping pad, the body would lose heat, drawn away by the cold ground. If camping on snow, lay down a ground tarp first to keep the pad and sleeping bag dry. Do not remove snow to sleep on the frozen ground, as the snow acts as an insulator. Bring a second sleeping pad for additional insulation. Extra clothes, or an empty backpack laid on the ground can also help. A small closed-cell foam pad can be useful around camp to stand on, protecting the feet from the cold ground, or to help fan the flames of the campfire.
These small packs provide heat to warm the hands or toes. Shake the packet after removing the packaging to begin the chemical reaction. After use, do not throw them on the ground, as that is not part of the Leave No Trace ethic. Instead, carry them out and dispose in the garbage. Heat packs can be purchased at outdoor retailers or hunting/fishing shops.
When the temperature drops below freezing, having a warm sleeping bag is important for having a warm night’s sleep. Even with a bag that is rated for zero degrees Fahrenheit or below, campers may want additional warmth. A fleece liner or an over bag can add to the warm of the sleeping.
