At 8 Hz, this frequency marks the lower end of the alpha wave range. It’s often associated with a light meditative state, helping users ease into calm. Studies suggest it can reduce anxiety by syncing brain activity to a slower pace. Therapists sometimes use this in sound baths to help clients unwind.

Binaural beats, where two slightly different frequencies play in each ear, often target the alpha range (8-12 Hz). They’re said to enhance relaxation by tricking the brain into syncing with the difference. Research from the National Institutes of Health supports their potential for stress reduction.
