In a world where restful sleep feels more elusive than ever, people are turning to everything from sleep trackers and blackout curtains to melatonin and meditation apps in search of better rest. Among the newer strategies gaining attention is the use of low-frequency sounds—deep, rhythmic audio tones designed to sync with the body’s natural rhythms. But can these sounds actually improve deep sleep, the most restorative stage of rest?
Scientific research and anecdotal reports suggest the answer may be yes. These subtle, often subconscious sound waves might hold the key to promoting more consistent, restorative sleep—especially for those struggling to reach or maintain the deeper phases of the sleep cycle.
