The Sleep zone
Sleep sounds that fade into silence
Sleep is thirty minutes of deep, steady sound with a breathing swell, fading out on its own. The screen turns to Night and nothing chimes at the end.

Questions about the Sleep zone
Does it help with insomnia?
Solfeggio is not a medical product and makes no health claims. If sleep is a real problem, talk to a doctor. This is sound for winding down.
Can it play all night?
Not yet. It stops after thirty minutes by design; ask the guide to make it longer.
