Saturday mid-morning I did one of my hot bikram yoga sessions. They are scheduled as 90 minutes long, but mostly you are allowed into the studio 30 minutes before class - and that's good for me. My pre-session routine mimics the normal class and so by the time the main class gets going my body is already warmed up so the sweat is dripping from me.
And so I get home and have lunch & breakfast in one. My wife had bought a loaf and since I was hungry devoured much of this with salad and hummus. Later I felt tired and decided to lie down for 30 minutes.
Hardly had my body hit the horizontal and I was met with truly awful cramps in both legs. Since lying there was definitely not an option I somehow managed to get myself vertical, and then walking around the pain subsided bit by bit.
Obviously I had not had enough after-class liquids and my body was dehydrated. Two pints of water later I could still feel the after-effect, including remnants of cramps in both feet. Sitting down was not on the cards, so I did some cooking in the kitchen.
My hypothesis is that the bread soaks up water in the body. My point / question is whether eating a large amount of bread contributed to the dehydration... I mean this session is not much out of my normal session plan of action. And over lunch I had had a couple of large green teas. I future of course I'll get more liquids inside me, especially if I have breads etc.
Bread? 
Gluten free seeded white bread.
