Researchers in Israel recently set out to figure out why interrupted sleep can be just as bad as getting no sleep at all.
They found that interrupted sleep patterns lead to reduced cognitive ability, reduced attention spans and bad moods.
In fact, the researchers determined that interrupted sleep was about as good as no more than 4 hours of uninterrupted sleep.
Participants in the study slept a normal 8 hour night, then experienced a night in which they were awakened 4 times during the night, for 10-15 minutes each time.
The following morning, participants filled out questionnaires to determine their mood and completed computer based tasks to determine their levels of attention and alertness.
A direct link was found between reduced levels of attention and negative mood after only 1 day of interrupted sleep.
A reminder that sleep quality is usually far more important than sleep quantity.
