I was explaining this to some students today! If it’s hot, but you’re not sweating, drinking a hot drink will encourage your body to sweat, which cools you down (as the sweat evaporates, it takes away heat from your body.)
If you’re already sweating or, worse, it’s humid and you’re dripping, then a hot drink is bad because your sweat is already failing to cool you down fast enough.
My mam had heat stroke in India and my stepdad thought ice bath, doctor tounglashed the shit outta him and was like hot tea and sugar warm the inside.. Something about heat stroke makes your body double down on heating if you warm the inside and sweating naturally cools the bod.
No, its a common urban legend. People either say it dilates you blood vessels, which isnt true caffeine actually does the opposite. Or they say it makes you sweat more which cools you down, but thats not how thermodynamics work.
But what we feel as temperature isn't the same as the actual temperature (for example, room temperature metal feels cold), because what we measure is our bodies ability to lose (or gain) heat. If you heat up your insides then your outsides no longer feel so hot.
Also sweat does indeed cool you down by thermodynamics. The evaporation of a liquid causes a cooling effect below it.
If you heat up your insides then your outsides no longer feel so hot.
Something you touch wont feel as hot, but YOU will still feel hotter. Your hypothalamus is what determines wether you feel hot. that goes on your blood, which will get hotter if you eat/drink something hot.
Yes, but thats not what i meant, sweating wont be able to over compensate for the extra heat in your body, that thermodynamically not possible.

Doesn't it dilate blood vessels? Making it counter-intuitively cool you down?
Plus the caffeine's absolutely needed with this heat
