My wife has really low blood pressure and for that and a few other reasons she is terrified of trying hot yoga. I’ve been at it for only a few months and after 10 years of traditional Japanese karate and two knee surgeries, I know that hot yoga is the way for me right now. My wife thinks that she will pass out or throw up in the heat alone. I’ve tried to explain that while they don’t let you leave, you can certainly just lay down through most of the standing positions. She counters with fear of her low blood pressure. Any advice specifically for low blood pressure and/or ways to survive the first few classes? Thanks, Adam
