German researcher found out that people sleep one hour too less to achieve maximal life satisfaction. On a normal weekday people sleep 7 hours per night on average. People sleeping one hour more (8 hours per night) are more satisfied in life.
The study was recently released in the Journal of International Review of Economics.
The authors of the study say: “Sleep is a very important part of our lives. It provides restoration, renewing energy levels, and as burgeoning medical research investigates helps the brain support and promote mental health.”
“Despite this importance, little is known about life satisfaction and sleep duration. Using German panel data, it is shown that sleep is an important factor for life satisfaction and, furthermore, that maximal life satisfaction is associated with about 8 h of sleep on a typical weekday.”
