How to Fall Asleep During the Day
To fall asleep during the day, try to block out as much light as possible from your sleeping area. For example, try shutting the curtains or wearing an eye mask to cover your eyes. To minimise disruption, turn your phone and other electronics to mute so they don't wake you up while you're sleeping. Alternatively, try playing the sounds of rainfall or waves to block out any noise. If you need to sleep after a night shift, you should be in bed within 30 minutes of arriving home to encourage a healthy sleeping habit.
