Breathwork is the conscious controlling of how you breathe in order to reach a specific outcome, which in this case is preparation for sleep. All of these practices stimulate the parasympathetic branch of your nervous system, responsible for ‘rest and digest’, shifting your mental and physical state to one that is less stressed, more restful and calm. If you're pregnant, it is not recommended that you hold your breath, so please pass on this practice.
