Nature's Sound Sleep - Rocky Beach Brown Noise (8 Hr)
NO EARBUDS OR HEADPHONES REQUIRED. ~5 REM cycles. Drift off to sleep to actual field recordings of a pebbly beach. Not synthesizers, no predictable distracting loops. These natural sound tracks are more effective than standard noise tracks because they include isochronic tone brainwave entrainment frequencies that match the timing and the frequencies associated with an scientifically demonstrated optimal 8 hours of sleep. Perfectly timed square waves spanning 10Hz to 1Hz (Alpha - Theta - Delta) influence your brain giving you the best REM cycles and groggy-free waking. Nature meets science: the Frequency-Following Response (FFR), is the natural tendency of the brain’s electrical activity (brainwaves) to synchronize with the rhythm of external, repetitive stimuli. When the brain is exposed to consistent auditory (isochronic tones) stimulus, the neural ensembles in the cerebral cortex adjust their own electrical oscillations to match the frequency of that stimulus.
