I plan to publish a number of post on staying safe when outside for some time. I should be able to combine all these tips into a single document to forward to people just before we start out to the Frozen Film shoot.

We all need to think about a few things in this order:
• Be Safe, Watch Over Your Body in Cold Weather
• Be Safe and Watch Over Your Hiking Partner (Always Hike in Groups of 2 or More)
• Be Safe and Watch Out for Your Equipment
• Bring Back Master Pieces

The University of Iowa Hospitals& Clinics published these tips. Web link below.

Winter weather can be nasty and two of the meanest winter culprits are hypothermia and frostbite. Hypothermia--When your body is unable to maintain a core temperature of 95 degrees F, you begin to shiver, your speech slurs, your breathing slows, your skin is cold and pale, your coordination suffers, and you are lethargic and apathetic. Young children, the elderly, and the ill are the most vulnerable.

Wet, damp clothing, an uncovered head, and inadequate clothing can contribute to hypothermia. Other conditions that make an individual susceptible include excessive consumption of alcohol, cardiovascular disease, and an underactive thyroid.

To treat hypothermia, bring the person out of the cold. Remove wet clothing and replace it with warm, dry clothing. Wrap the person in blankets. Call 911 for emergency assistance. Provide a warm drink--do not give the person alcohol.

"Persons pulled from icy water should lay still, be dried and covered. Movement of the extremities can cause cold blood to return to the heart, resulting in a life-threatening change in cardiac rhythm," says Eric W. Dickson, M.D., director of the Emergency Medicine Program at UI Hospitals and Clinics.

Frostbite--Skin on fingers, toes, earlobes, cheeks, and noses are the most vulnerable to prolonged exposure to freezing temperatures, wet clothes, and forceful winds. Blood vessels near the surface of the skin constrict to preserve internal body heat, reducing blood flow to the skin. The result is frostbite. Frostbite ranges from white or yellowish skin accompanied by itching or burning sensations, numbness, and in the most severe cases, blistering.

To treat frostbite, bring the person out of the cold. Remove wet or constricting clothing, including jewelry. Call 911 for emergency assistance. DO NOT rub frostbitten areas or apply direct heat.
