Sleep
A sound to rest with. It can cover the noises that would pull you awake. It is not a treatment for insomnia, and it does not promise you will sleep. Keep it quieter than a conversation.
Volume
55
Fade out
It fades after 45 minutes, so it doesn’t play all night.
Stop if the sound feels worse. If nights have been hard for a while, a person trained for that is the right next step. If you are in danger, call 999 or Samaritans on 116 123. Help.
