Good quality sleep may be better than the recommended seven to nine hours of shut eye for a happy and healthy life, new research suggests. Those who reported being able to drift off within 15 minutes and stay asleep through the night also reported having a better quality of life compared to those who did not.
The study, published in Plos One, followed 4,000 people in the Czech Republic over a period of three years. Adults responding to the researchers' surveys in 2018, 2019 and 2020. Quality of life was measured using five parameters: life satisfaction, wellbeing, happiness, subjective health and work stress.
The scientists wrote: "Better sleep means a better quality of life. While when we sleep and how long we sleep is important, individuals who have better quality sleep also have a better quality of life, regardless of the time and length of sleep."
