After setting a new time record every day, your colleagues’ request for coffee leaves you questioning their sanity. Why would anyone drink a hot steamy cup of coffee in this hot weather? You’d rather have lemonade on ice to cool of the heat.
Well, if you think that hot beverages make you hotter, you are wrong. You can beat the heat with some more heat. How? Let’s learn more about this phenomenon.
What Does The Science Say?
A research was conducted with a sample of 9 men.
The men were asked to cycle for 75 minutes, while being exposed to a running fan. The wind evaporated sweat as soon as it started forming, when the exercise was over, the men were given water of different temperature.
The temperature of the water varied from 35 degree Fahrenheit (cold) to 122 degree Fahrenheit (hot). Researchers found that there was a huge difference of energy release when participants drank hot and cold water.
Against the contrary belief, men who drank hot water released 56 kilojoules of heat energy. On the other hand, men who drank cold water end-up gaining 21 kilojoules of energy. Hence disregarding the common belief, that cold beverages cool down body heat.
Energy Release Explained
In simple terminology, cold drinks can make you cool from the inside, without actually making you cooler. How does this happen? The cold fluid that you drink inhibits the sweating mechanism of your body, making you feel cold.
So, all the mystery lies in sweating. You lose 2.43 kilojoules of energy when your sweat evaporates from your skin. In the above-mentioned study, the men who drank hot water gained 52 kilojoules of heat from fluid intake. This was later released from their body in form of sweat, which caused them to lose 108 kJ (kilojoules) in form of sweat.
On the other hand, men who consumed cold water prevented their bodies from heat release in form of sweat evaporation. The men cooled down at 138 kJ, which was not sufficient to counter react the 159 kJ of heat retained in their body. So they ended up gaining more heat.
In simple words, hot drinks make you sweat more, which causes you to lose more heat. So, should you be drinking custom roasted coffee throughout the scorching heat of July.
