We all went into the Sauna for a bit inbetween sessions at Oxford Hyperbarics.
There is a big long list of things the infared sauna is good for. It was moisture free (no steam) so apparently it is safe to even take your computer in there!
We did work up quite a sweat though! Mummy and Daddy stayed in longer than Corey and I. Corey had great fun being the "sweat investigator". Daddy and Corey easily worked up a sweat. It took a little while for Mummy and Blaise to get sweaty!
