Binaural beats for sleeping?

Binaural beats may help you relax, but whether they reliably induce deep-sleep brain waves or improve sleep is uncertain. The cited sleep-related evidence concerns low-frequency sounds and sleep generally; it does not establish that binaural beats reliably produce that effect. 1

• 1. Apps’ delta-wave claims: Apps may offer beats with goals such as falling asleep, and delta activity is associated with sleep. But the discussion does not establish that listening to binaural beats reliably induces delta waves or improves sleep. 1
• 2. Other possible effects: Some studies report modest benefits for cognition, attention, and working memory, while the strongest effects described are anxiety and pain reduction—not sleep improvement. 2
