I was wondering about the effect on homeostatic regulation of imbibing hot fluids such as tea and coffee. In particular I was wondering about the effects of so doing during a period of hot weather and high humidity.

 

I suppose one should really frame the question around the drinking of hot water, as the caffeine content of tea and coffee may introduce variables, but as most of us drink our hot water with caffeine in it, perhaps not!

 

Do you think there is any truth to the notion that drinking hot fluids during hot weather is both refreshing and in some way keeps the drinker cool, and why?

it ultimately cools the drinker because the drinker will sweat more. the more you sweat the cooler you get.

 

and with a cold drink while it will cool you down initially, you will sweat less and heat up more later on.

I always thought that when drinking hot fluids your body will feel much hotter. however as time progresses you will sweat more and feel much cooler. i prefer drinking cool drinks, i could never drink hot fluids on a hot day.

Drinking cold drinks will also close the pores on your skin thus inhibiting transpiration.
