Ocean waves
Slow waves rolling in on a quiet beach at night.
Slow, rhythmic waves give your breathing something to follow. Each wave is about twelve seconds, close to a relaxed breath in and out.
Tip: keep the volume low, around the level of a quiet conversation, and set the timer so it fades out after you're asleep. On a phone, keep the screen on or the browser may pause the sound.
Want it on the TV or without your screen on? Listen on our YouTube channel — 10-hour versions that fade to a dark screen.
