Something I use to judge how hot the room is.
I buy a 1.5 litre bottle for each session. At the end of the session, most of the time, the water is still more cold them warm, it just tastes (if that’s the right word!) like it’s some cold water that’s left been out too long, and very often i will have had a good session.
Other times, at the end of the session, the water in the bottle is like drinking bath water, and invariably it will have been a very tough session.
A crude measure indeed, but it helps me judge whether or not the room is too hot! Not sure whether or not in optimum conditions (40 degrees?) the bottle test is “cool” or “bath water”!
