Actually today I was just scrolling down my feed …..as many of you do as well….or I think I should correct myself ….almost all of us do that…..but while scrolling I saw something like what our today’s topic is looking like……Yes, I know you are curious to know how can this happen….or you think on the other side …..I could me MAD to put these type of topics just to bring more views on my website.
HOLD ON!! WELL, FIRST OF ALL, This is no joke …..It is actually a fact.
Yeah, it sounds stupid and counterproductive, but if you want to cool down, then drink something hot.
So, now let’s get straight to the point:-
I remember as a child, on the rare warm days that we used to get in India, my grandmother telling me to “have a cup of black tea … it will help cool you down”. As a seven-year-old, this seemed like a crazy idea, especially when all I wanted was cold lemonade and another ice cream.
But according to a study from the University of Ottawa’s school of Human Kinetics, as the drink is hotter than your body temperature, it triggers a sweat response in the body that more than compensates for the increase.
An explanation for these findings appears to be related to how sweating may be influenced by drink temperature. Sweating, and more importantly the evaporation of this sweat, is one of the key avenues for modulating body temperature and maintaining heat balance.
Due to the increased heat load from drinking a warm drink, there is a compensatory increase in overall sweat output, which outweighs the internal heat gain from the warm drink. Consistently, a 50˚C drink results in a higher whole body sweat loss (around 570ml vs about 465ml for 1.5˚C). In practical terms, this means that more sweat is produced which is evaporated from the skin surface, increasing heat loss from evaporation and reducing body heat storage.
Importantly, however, this study was conducted under conditions that allowed complete evaporation of sweat – in other words dripping sweat was limited by maintaining a good airflow and keeping humidity low. The results would likely be different in conditions where sweat evaporation is limited, such as in hot and humid conditions. In fact, drinking cold drinks may be more favorable in these circumstances, minimizing inefficient sweat losses – dripping sweat – and consequently aiding an individual’s hydration status.
So, depending on your environmental conditions, maybe reaching for that cup of tea isn’t such a crazy idea after all. Plus the moral of the story: listen to your grandmother’s advice – it’s based on years of experience.
