Hyperventilation
Hyperventilation or over-breathing can have important consequences. It paradoxically starves the brain of oxygen and affects
performance on different levels:
- physical - laboured breath, chest pains, fatigue, nausea,
headaches
- mental - poor concentration, fuzzy-headedness, impulsiveness
- emotional - anxiety and panic, depression, emotional volatility.
It's a common, almost instinctive response to stress and anxiety.
Under stress the breath tends to quicken and shift higher in the chest.
Carbon Dioxide & Why It Matters
The single most important factor in optimal breathing is carbon dioxide. Although
it's a waste product,
carbon dioxide serves vital functions in the body. Over-breathing depletes carbon dioxide
levels in the blood, and it's this that leads to the negative effects listed above.
Most breathing training focuses on the mechanics of breathing - how fast, how deep -
without necessarily addressing carbon dioxide levels. You could learn
very "proper" breathing mechanics - diaphragmatic breathing, etc. -
and not affect your carbon dioxide levels - or even make them worse.
Capnometry
A capnometer is a device that measures carbon dioxide levels, and
it's the only sure way to know whether you are over-breathing.
Feedback from a capnometer greatly facilitates learning to
breathe optimally. In my clinical experience, raising carbon dioxide levels (where they are low)
is virtually guaranteed to help you feel better.
Breathing biofeedback has a role to play in virtually all the conditions listed in
the What Does It Help? page.
