Approximately three-fourths of people diagnosed with a depressive disorder also report sleep disturbances. Individuals with depression experience REM sleep earlier than others, and they spend less time in slow-wave sleep, according to EEG studies. Many people use electronic devices before turning in for the night, a habit that may be interfering with sleep patterns. Sleep researchers believe electronics suppress the release of a hormone called melatonin that assists the body in falling asleep. Reading or other relaxing activities are less likely to hinder sleep. Developing a relaxing bedtime ritual is beneficial.
