I often drink hot coffee during cold weathers, especially from months of November to February. Some drink hot chocolate or hot tea and alcohol for drinkers.
Department of Health stated that these beverages can help but may cause dehydration and more chilling. Chilling can kill. It cause a fast loss of heat that can result to hypothermia. Its better to drink hot soup instead.
Hypothermia is a condition in which core temperature drops below that required for normal metabolism and body functions which is defined as 35.0 °C (95.0 °F). Body temperature is usually maintained near a constant level of 36.5–37.5 °C (98–100 °F) through biologic homeostasis or thermoregulation. If exposed to cold and the internal mechanisms are unable to replenish the heat that is being lost, a drop in core temperature occurs. As body temperature decreases, characteristic symptoms occur such as shivering and mental confusion.[wikipedia]
The best alternative to fight chill in cold weather is to wear thick clothes like sweater, jackets, jogging pants, gloves and socks.
