Cortical Cooling Frequency Sleep

Emerging sleep research suggests that lowering cortical temperature is one of the most effective triggers for sleep onset. This therapeutic recording uses precisely calibrated low-frequency tones in the 0.5-3 Hz range that are theorized to complement the natural cortical cooling process that occurs as the brain transitions from wakefulness to sleep. The extremely low frequencies create a barely perceptible pulsing sensation that encourages the parasympathetic nervous system to dominate, slowing heart rate and reducing core body temperature. The tones are layered with a subtle ambient carrier that provides listening comfort without interfering with the therapeutic frequencies. This is experimental audio therapy at the frontier of sleep science. Ten hours of continuous playback with precise frequency calibration maintained throughout. Ideal for people with thermoregulation-related sleep disorders, night sweats, menopause-related insomnia, or anyone who runs hot at night and struggles to fall asleep. Eight hours of continuous recording, maintaining precise frequency calibration throughout, providing a complete, uninterrupted night of thermally optimized sleep.
