Throughout the day, the brain exhibits patterns of activity known as brainwaves. These can be measured using an EEG and fall within a few defined ranges that correspond to different mental states:
• Delta (0-3 Hz) — deep sleep
• Theta (4-7 Hz) — REM sleep, deep relaxation, meditation
• Alpha (8-13 Hz) — relaxed alertness, wakefulness
• Beta (14-30 Hz) — concentration, active thought
• Gamma (30+ Hz) — learning, problem solving, peak cognition
Binaural beats allow you to tune your brainwave frequency on demand, increasing it when you need to get energized, or lowering it when you need to relax or sleep. Think of it like having a dial to speed up or slow down your brain.
