Sleep Foundation

Late screen time

Screen-time from mobile phones, computers, and televisions present a range of problems for sleep. These include:

• Distraction from attempting to go to sleep.
• Stimulation of the mind when it should be moving into a sleepy state. This may be particularly problematic if screens are used in bed.
• Blue light emitted from screens. It is thought this can trick our brain into thinking it is daytime and thus not the time to go to sleep.

• Turn screen devices off in the earlier evening.
• Keep mobile phones out of the bedroom.
• Use an app that removes blue light from the screen in the late evening.
