I've never sweated so much in my life - this I am sure of!! Sometimes it's difficult to stay hydrated, even when drinking water constantly. I'm easily going through 5 liters or more water per day. I was never much for cold showers but I haven't reached for the hot water faucet yet! The posada I'm staying in now is pretty nice - they have a pool to enjoy and I have a small jucuzi tub in my room which I fired up yesterday. It was great for doing some laundry also!
