Answer 1

Your body tends to acclimatize to what the temperature is. so if its hot most of the time, you’ll get used to hot temperatures and feel that 21 is cold. If its cold you’ll get used to the cold, and 21 is warm.

​

that’s why when you go outside in the winter it’s really cold, but then you get used to it. Still cold, but as long as you’re wearing enough layers, you’ll be fine. Same as in the summer, when you go outside from the A/C you don’t sweat right away, but then you start sweating as you get used to it as your body tries to cool your body down.
