Ist da überhaupt was dran? Hört sich nach Quacksalberei an.
Grad mal geschaut und die Antwort ist Jein wobei ich das eher als Nein einordnen würde.

Ein Ausschnitt:
If a drink is warmer than the body, at first, "Obviously, that drink makes you hotter," McNaughton said. But humans, like all warm-blooded animals, are constantly adjusting to maintain a consistent internal temperature. McNaughton found that hot drinks (and spicy chilis) activate a receptor in our nerves called TRPV1, which tells the body it needs to cool down. In response, humans sweat.
Sweat pooling on skin is uncomfortable, but add a breeze or a fan, and the air blowing past helps sweat evaporate, taking heat with it.
Also nein kühlt definitiv nicht sondern bringt dich nur zum schwitzen. Ob das dann Netto zu einer Kühlung des Körpers führt ist Situations abhängig (Luftfeuchtigkeit, Kleidung, Wind). Wenn man tatsächlich Gefahr läuft zu überhitzen, dann lieber kalte Getränke und Körper befeuchten.
In the reverse effect, cold drinks lower body temperature and then nudge the brain to reduce sweating in order to bring body temperature back to its baseline. A 2018 paper suggests that with less wind, more humidity, or other barriers to effective sweating — like the heavy clothing worn by firefighters — it may make more sense to cool off by drinking crushed ice. "Cold water will definitely make your body colder," McNaughton said. "It will tend to suppress sweating as well. If you're already dripping with sweat, that may be rather nice!"
