Physiology & Medicine / Deep heat makes stomach contract
« on: 06/06/2009 12:27:40 »
I've found that whenever I have been somewhere hot for a while e.g. sunbathing, hot bath, sauna, when my body reaches a stage where the heat has penetrated deep to my bones, I have what feels like a reflex spasm in my stomach muscles. Why should that happen and has anyone else experienced this as I've never seen it mentioned anywhere?
