Just curious!
I'm a 'hot' person - I generate heat easily and I'm always the hot one in the room. I also drink a lot - 2 to 3 litres of water plus a litre of tea, more in summer. My thirst can't be explained by bad diet or excessive exercise. I'm not overweight and don't have any medical conditions.
I just idly wondered if they're connected. Are you a hot person who drinks a lot? Or a cold person who doesn't drink much?
