Pregnancy and breathing gymnastics
Pregnancy itself doesn't mean one should not do certain physical activity, including breathing gymnastics. It's more about another factors that define pros & cons, namely:
- general physical condition
- current emotional state
- lung capacity for the moment
- the desired effect from the trainings.
So if you are generally healthy, have an active life and feel well, you can practice whatever pattern you'd like, as long as it brings you joy. For that you need to choose proper training complexity). If you have any doubts, please consult your physician.
Also please make sure you don't over-do breath holding phases ("retain" and "sustain" in the app). If and when you do them, note you may feel baby kicking during your practice; it's quite normal, as a baby moves actively in order to get more oxygen. It does no harm to the child.
By the way, if you are on this page - our congratulations! That means you are (or soon going to be) pregnant, or, if you're a man, your dear wife/sister/friend is. Or you are just interested in this topic, which is also good. Anyway, please make sure your main tool for decision making is based on common sense and on trust in your own feelings. Surely, a piece of advice from doctor/friend/indie-developer's wife can be quite valuable, but it is you who is bearing a child, and it is you who is responsible for your lives. Wish you lots of precious moments together!
