Lots of research and articles by scientists explain just how breathing and how you breathe can connect to the brain and different parts when not our automatic action of breaths.
There are different types of therapies such as Cognitive Behavioural Therapy, trauma therapy, or various types of spiritual exercises which all involve focusing and regulating breathing but does controlling inhaling and exhaling have any profound effect on your behaviour? This is the question many researchers have been trying to discover. So far it has been researched that it can gain control and aid towards calmness and focusing more.
Focusing on breathing or doing breathing exercises could adapt the brain. This has potential in a range of jobs that require extreme focus. Athletes, for example, have long been known to improve performance statistics with their breathing.
These studies can be found via the study, conducted by my post-doctoral researcher, Dr. Jose Herrero, in collaboration with Dr. Ashesh Mehta, a renowned neurosurgeon at NorthShore University Hospital in Long Island.
