Drinking tea has been linked to a variety of benefits: from reducing the risk of heart disease, lowering blood pressure, boosting immunity to aiding weight loss, but it’s often said that hot tea can cool us down in the summer, and scientists have checked to see if this is really a myth or fact.
Chemist and researcher Dr Tim Bond said hot drinks like tea can indeed cool us down in hot weather, which is why it is consumed in large quantities in India.
He explained that studies have shown that, with complete evaporation of sweat, body temperature drops more after drinking hot tea than after drinking a cold drink.
A study of cyclists on hot days found that cold drinks reduced heat and sweating more than hot drinks. The reason may be changes in heat sensors in the esophagus and stomach. That is, the nerves in our mouth and upper digestive tract respond to heat, and sensors in the brain tell us to produce more sweat. When the sweat evaporates, it effectively cools us down.
And, you also need to know when it’s best to drink hot tea rather than cold.
If the moisture percentage is high, not all of the sweat will leave the surface of the skin. If you are wearing too many layers of clothing, or if you are sweating so much that the sweat is dripping off your body instead of evaporating, then drinking hot drinks is not a good idea and drinking cold drinks is better.
Bond concludes: “The caffeine content in tea may improve our cognitive processes without reducing fluid intake. Clinical studies have also shown that tea has the same hydrating properties as water and contributes to normal water balance.” night.
