A good night’s sleep is like hitting the jackpot


Working on getting a better night’s sleep can lead to optimal physical and mental well-being over time—but quality of sleep is more important than quantity.

For a new study, researchers analyzed the sleep patterns of more than 30,500 people in UK households over four years and discovered that better sleep leads to levels of mental and physical health comparable to those of somebody who’s won a jackpot of around £200,000.

Positive changes in sleep over time—improved quality and quantity, and using less sleep medication—are linked with improved scores on the General Health Questionnaire (GHQ), which is used by mental health professionals to monitor psychological well-being in patients.

People surveyed who reported positive improved sleep scored a 2-point change in the GHQ—a result comparable to those recorded from patients completing an eight-week program of mindfulness-based cognitive therapy designed to improve psychological well-being.

Furthermore, the same people showed improved scores on the 12-Item Short Form Survey, which tests levels of physical and emotional health, as well as people’s ability to perform everyday activities.
Conversely, it was found that a lack of sleep, bad quality sleep, and using more sleep medication can lead to worsened medical and emotional states.

The findings, published in the journal Sleep, show that improving the quality and quantity of sleep—and discouraging the use of sleep medication—is an effective, simple, and cheap method of raising health and well-being, says Dr Nicole Tang, a psychologist at the University of Warwick.

“We are far from demonstrating a causal relationship, but the current findings suggest that a positive change in sleep is linked to better physical and mental well-being further down the line.
