Do not venture out if you do not have to. If you do need to go out, limit your exposure, and know your limitations. Dress in several layers, and wear a waterproof and or windproof outer layer.
Should your clothes become wet, remove your self from the environment and remove the wet clothing immediately.
Finger tips, earlobes and noses tend to be highly susceptible to frostnip and frostbite. Keep these areas covered while out in the cold weather. The body loses approximately 40% of its heat through the head. Wearing a hat will help conserve body heat.
Frostnip is a common and reversible result of exposure to the cold. Persons suffering from frostnip can easily rewarm cold fingers, toes or nose by gently rubbing these areas briskly.
Frostbite however is a more serious condition caused by long exposure to the cold. This, if left untreated may result in the actual freezing of an extremity, digit or nose. Do not attempt to rewarm a frostbitten extremity by rubbing it. Re-warming must be done gradually and in an Emergency Department.
The very young, the elderly and or informed also tend to be prone to cold related injuries. It is important to monitor children, and to regularly check on elderly relatives or neighbors.
If you anticipate being out in the elements for an extended period of time do not smoke or consume alcohol. These items cause changes in the circulatory system making the body even colder.
Make sure you have a working smoke detector in every bedroom and on every level. Check and change the batteries often.
Do not attempt to heat your home with the oven. Burning gas in a closed house or apartment uses up oxygen and produces deadly carbon monoxide gases.
