Older adults who have a good reason to get out of bed sleep better at night, researchers report.
Academics at Northwestern Medicine and Rush University Medical Center, Chicago, studied over 800 people with an average age of 79 and surveyed their purposes in life and general sleep quality.
Overall, those participants who felt their lives had meaning were 63 percent less likely to have sleep apnea, a condition characterised by pauses in breathing or periods of shallow breathing during sleep.
