The Globe And Mail
A hot drink cools you faster than a cold one – a myth or reality?

It's one of the great urban myths of summertime – that drinking a cup of piping hot tea will kickstart your sweat glands and ultimately cool you down more than an ice-cold drink. Or is it?

New TEL publication in Acta Physiologica (Oxf.) (May, 2012)
A new TEL paper published in Acta Physiologica (Oxf.) reports that ingesting hot (50ºC) drinks during physical activity may actually lead to a smaller amount of heat stored in the body relative to the ingestion of cold drinks.
