A new study has revealed that people who go to bed later have better moods than people who go to bed earlier but their sleep is broken up during the night.
Study’s lead author, Patrick Finan, an assistant professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine said “When sleep is disrupted several times during the night you may never get to slow wave sleep.”
The researchers observed the impact of disturbed sleep in 62 healthy men and women who agreed to spend three nights in a sleep lab.
Sleep expert Peter Franzen, an assistant professor of psychiatry at the University of Pittsburgh School of Medicine while reportedly commenting on the study said “There are many, many studies that have looked at the impact of sleep restriction, as opposed to multiple awakenings, which is probably more valid way of looking at insomnia.
“With this kind of model you can begin to tease apart the effects of fragmented sleep.”
Fragmented sleep is a type of insomnia that prevents people from falling asleep.
