Hot or Cold Cider this Winter?
Recent research at the U.S. Army Research Institute of Environmental Medicine indicates that warm drinks in small amounts do not contribute to increased body temperature. Drinking hot fluids can actually cause small amounts of heat loss by causing skin blood vessels to dilate. You would have to drink one quart of a hot liquid all at once to significantly increase overall body heat.
Heated drinks may hit the spot on a chilly evening and thus, mentally, give a warm feeling. The converse is also true. But consuming cold liquids during cold weather will not decrease body temperature. A consistent intake of fluids--warm or cold--is an important part of winter health.
