Question

“Hi Vanessa, I have a question about doing yoga while pregnant: I’ve been practicing yoga for over 15 years. Living in northern New England, nearly all of the yoga classes I attend are heated to some degree. Most studios list a 5-10 degree temperature range for each class (e.g. 75-80 degrees, 85-95 degrees, 110-115 degrees, etc). While I tend to avoid the hottest bikram-style classes, I’m wondering what temperature range is safe for an expecting yogini? I’ve also read that the mama-to-be’s internal temperature is a more telling indicator rather than the external temperature – do you know there’s any truth to this? Any input or guidance you can offer would be much appreciated!” – Sarah
