Alpha Brain Waves

Meaning

Alpha Brain Waves are electrophysiological oscillations of the brain, typically ranging from 8 to 12 Hertz (Hz), that are prominently observed during a relaxed yet awake state. Alpha waves signify a state of mental restfulness and disengagement from intense cognitive processing, often correlating with reduced stress and a balanced hormonal milieu. Clinically, their presence indicates efficient cortical idling and a transition away from the high-frequency beta activity associated with sympathetic nervous system dominance. The measurement of these waves via electroencephalography (EEG) provides a non-invasive window into the brain’s baseline regulatory state.
