OUR BRAIN WAVES
An important component of respiratory biofeedback is the production of healthy brain waves. The brain produces different frequencies and amplitudes of electrical waves depending upon our levels of consciousness. Sensation, attention (self-awareness), intellectual activity, and the planning of physical movement have distinct electrical correlates in the brain that can be measured using an EEG.
There are four commonly measured waves, and at least two others that have been observed:
Beta waves (12-32 Hz) are associated with full awareness and high cortical activity—typical of a busy brain, such as during a business meeting, planning a trip, or when mentally doing several things at once.
Alpha waves (8-12 Hz) are associated with a sense of “relaxed alertness” and high creativity—typical during meditation, listening to music, and when eyes are closed. The ability to generate alpha waves is associated with the self-regulation of stress and may contribute to an expanded state of consciousness.
Theta waves (4-8 Hz) are an awake but dreamy state common just before the onset of sleep; most prevalent in youth because the brain has not yet fully developed, they also occur during deep creativity and meditation in adults at any time.
- High-glycemic carbohydrates, especially sugar and processed flour products, can reduce and impair brain function due to the effects of insulin.
- Blood sugar can be controlled exceptionally well by snacking on healthy items. By eating five or six meals daily, you can help stabilize blood sugar, allowing the brain to do its job properly.
- Stress can wreak havoc on blood sugar and reduce overall brain function.
