Symptoms of carbon monoxide poisoning are similar to the flu but do not include a fever.It is produced by burning fuels such as wood, oil, natural gas, kerosene, coal and gasoline. It is colorless, odorless, tasteless and non-irritating. Carbon monoxide (CO) is a potentially deadly gas.Take precautions to avoid exposure to dangerous levels of carbon monoxide.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. 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.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. Be sure the outer layer of clothing is tightly woven to reduce body-heat loss caused by wind. In high wind conditions, cold weather-related health problems are much more likely. When outside, take extra precautions to reduce the risk of hypothermia and frostbite.Infants who are suffering from hypothermia may appear to have very low energy and bright red, cold skin. Early signs of hypothermia in adults include shivering, confusion, memory loss, drowsiness, exhaustion and slurred speech. The minimum temperature should be kept above 68 degrees Fahrenheit to protect the very young, the elderly, or people with health problems.
