Lately I am finding that a lot of people are struggling to sleep well. Individuals with mental illness seem to in particular have difficulty sleeping well. Screen time before sleep time is a problem. Many people are looking at screens (televisions, smartphones,i-pads,tablets) before bedtime. Screens disrupt your ability to fall asleep and your quality of sleep. The blue light emitted by these devices decreases the amount of melatonin released ( which peaks at bedtime) and will affect your quality of sleep (your deep REM sleep).  Thus I am suggesting that you stop using your devices 1 hour before bedtime. If you need to have your cell phone in your bedroom keep it and charge it far away from where you sleep to decrease the temptation to use it.
