Not saying your prefs are wrong but just fyi: hot drinks are best in hot weather, people who live in the desert (arabs, nomads for example) have traditions where they drink coffee or tea at high noon very hot. Same with cold weather, iced drinks and ice cream are best when the weather is cold.

The reason they told me is that your sensitivity to temperature is relative to your internal temp. Drinking a hot drink raises your internal temp, reducing the relative gap with the outside temp and therefore making you feel less hot. Salty food and hydration are adequate to let your body naturally stabilze to the temperature. Of course there are limits.
