Heated Yoga in 1st Trimester

Marisa
Hi ladies,
​I just thought I would share this information that I didn't know until today. I'm a regular yoga student/teacher and have always thought yoga was good during the entire course of pregnancy with some modifications.
​I felt pretty light-headed in a recent class and emailed my dr to ask. Apparently, heated yoga during the first trimester has been linked to birth defects in very recent studies and should be avoided until trimesters 2/3. I just wanted to pass that on if there are any other yogis out there. Unheated yoga is fine. 
​Best of luck to all!
