Health Department Advises Taking Precautions in Frigid Weather
Albany, January 19, 2000 – In the wake of recent sub–freezing temperatures in New York and the Northeast and a continued frigid forecast, the State Health Department is urging New Yorkers to take precautions.
In extreme cold conditions, some people, such as infants and the elderly whose bodies can not easily regulate their temperature, are at increased risk for hypothermia. Hypothermia is a life–threatening condition that causes the body's core temperature to drop. Warning signs of hypothermia in adults include shivering, confusion, memory loss, drowsiness, exhaustion and slurred speech. Infants who are suffering from hypothermia may appear to have very low energy and bright red, cold skin.
Accidental hypothermia can occur even with temperatures of 60 to 65 degrees. In homes of people who are over 65, the thermostat should be set no lower than 65 degrees, or 70 degrees if the occupants are 75 or older. Infants less than one year of age should never sleep in a cold room and should be provided with warm clothing and a blanket to prevent loss of body heat.
Frostbite is another cold weather concern, and is especially dangerous because it often happens with little warning. Numbness can occur so quickly that the individual, unaware of being frostbitten, may remain outside, increasing the chance of permanent damage. Older persons, and those with diabetes, are especially vulnerable to frostbite because of impaired circulation.
Frostbite occurs in three stages: First degree frostbite usually causes a whitening of the skin, followed by redness, tingling and loss of feeling. In second degree frostbite the skin turns purple and blisters begin to form. Third degree frostbite, which can affect those exposed to severe cold, can lead to gangrene and amputation. Skiers, ice skaters, hikers and snowmobilers should stop frequently to check exposed areas of their body for loss of feeling and other danger signs.
To prevent frostbite and hypothermia, it is important to dress warmly in wind–proof clothing and to go indoors when you begin to feel cold. Wear several layers of loose–fitting clothing to trap body heat. Fasten buttons or zippers and tighten drawstrings securely.
Don't forget gloves, mittens and a hat that covers the ears. Be sure the outer layer of clothing is tightly woven to reduce body–heat loss caused by wind. As the speed of wind increases, it can carry heat away from the body faster. In high wind conditions, cold weather–related health problems are much more likely.
Since cold weather puts an extra burden on the heart, if you have cardiac problems or high blood pressure, follow your doctor's orders about shoveling or performing any strenuous exercise outside. Even otherwise–healthy adults should remember that their bodies already are working overtime just to stay warm, and dress appropriately and work slowly when doing heavy outdoor chores.
If you will be spending time outside, do not ignore shivering – it is an important first sign that the body is losing heat and a signal to quickly return indoors.
