Hot coffee on a hot day


If you believe the forecast then the UK is soon to be basking in some beautiful sunny weather, so while you are topping up on some much-needed vitamin D some say that you should cool down with a hot coffee.

Whaaaaat!?!?  I know right!?!?!  Ok so here is the theory.

According to Ollie Jay, a researcher at University of Ottawa’s School of Human Kinetics, drinking a hot brew can actually cool you down, because it results “in a lower amount of heat stored inside your body”.

How?  Well, a hot drink adds extra heat to your body, which causes the body to kick off its’ cooling response: sweating. As sweat on the skin begins to evaporate, it cools you down. Voila.

The reports that we have read also go on to say that this theory is also dependent on environmental factors.  For example, if you are drinking a hot drink in a humid environment, then the sweat won’t evaporate and therefore the theory does not work.  The same applies if you are wearing clothes which fully cover your skin.

“On a very hot and humid day, if you’re wearing a lot of clothing, or if you’re having so much sweat that it starts to drip on the ground and doesn’t evaporate from the skin’s surface, then drinking a hot drink is a bad thing,” Jay.

So, the next time you’re looking to cool down on a hot day, reach for nice hot coffee as long as you are in swimwear (and your meeting camera is off!!)
