In 2012, Dr. Olly Jay, a researcher at the University of Ottawa School of Human Kinetics, published a research result verifying what changes would occur in the participants' body by comparing warm and cold drinks. did. Mr. Jay gathered nine men, they hit a fan and evaporated sweat, they had cycled for 75 minutes. After that, men drank water of 1.6 degrees Celsius to 50 degrees Celsius, and the difference between them was verified.

As a result, it was said that there was hardly any difference in thermal energy due to metabolism or body temperature depending on the temperature of water drunk. Strictly speaking, the group who drank hot water promoted perspiration, sweat evaporated and the heat was deprived, the amount of heat loss became slightly larger than the group drinking water at room temperature, but drunk cold water Although the group generates heat loss in the body, sweating is suppressed, so the total amount of heat loss is slightly smaller than the group drinking water at room temperature.

When I drink hot drinks on a hot day, I get sweating promoted and it may be cooler due to heat of vaporization, but Mr. Jay warns me, "I have never recommended the act of drinking hot tea in the afternoon of August" It is. Because this experiment was carried out in front of the fan, all perspiration evaporated and it led to heat loss, but it is hard to think that all sweat will evaporate in the normal situation, so "a lot of drinks with hot beverages Sweating "does not apply to lowering body temperature as it is. Also, in this experiment, although the amount of perspiration varied depending on the temperature of the water, the temperature in the body of the drinker did not change.

In other words, the question "Is it cool if you drink a hot drink on a hot day?" Is YES, but it means that there is no dramatic effect. Popular Science concludes that "If you want to cool your body on a hot summer day, it would be best to move indoors or out of direct sunlight."
