In 2015, a group of sleep researchers conducted a study on 62 healthy men and women. The participants were randomly subjected to three different experimental conditions: being forced to wake up during the night; going to bed late; and uninterrupted sleep.
The results show that an interrupted night’s sleep is worse than a short night’s sleep. The study’s lead researcher, Patrick Finan Ph.D. explains that disrupted sleep prevents you from progressing through the sleep stages. That means if you wake up at intervals during the night you don’t get enough deep, slow-wave sleep — the kind that makes you feel rested and restored.
So setting the conditions for peaceful and uninterrupted sleep is actually more important than trying to go to bed early and sleeping longer hours.
