I had a friend tell me the other day that for the first day of her period she pushed herself during a hot yoga class - and she felt super tired. Then the next day she was planning on going rock climbing. This is what I told her: Hot yoga, inversions and overdoing it during your bleed (especially the first few days) is a no no. Your hormones are at their lowest. It is not a time to push and over do it. It's a time to rest. "I feel lazy though if I miss a day." We are not meant to push hard every day. Especially during our bleed. We live in a society that tells us to "suck it up" "keep pushing" so even when we don't have to we still feel the need to do so. Movement during your bleed is okay... but it is the type of movement that you do. Light walking, restorative yoga, gentle stretching.... these things honour your body, not override it and push it when it is asking for rest. You want to avoid, weights, intense cardio, strenuous workouts - for the first two days. And NO HOT YOGA during your period (or cold plunging).
