Is it true that ... having a hot drink will cool you down?
A warm cup of tea can trigger sweating and lower your body temperature, but only if you’re in an airy space

TL;DR
- Drinking a hot beverage can increase body temperature, leading to more sweating.
- Sweat cools the body through evaporation, which removes heat energy.
- The effectiveness of sweat evaporation depends on the environment: it works well in breezy conditions but poorly in high humidity or with poor ventilation.
- In humid or poorly ventilated environments, drinking a hot drink can actually make you hotter.
- The key takeaway is to stay hydrated with fluids of any temperature, especially in hot weather; personal preference dictates whether hot or cold drinks are better.
