The scientists conducted a telephone survey of more than 150,000 adults of different ages who were asked if they had trouble sleeping or if they were tired during the day. In addition, the analysis included variables such as race, education, income, mood, health, and time since the last medical check-up.
The results indicated that people with health problems and depression suffer more sleep problems. In addition, women suffer from more sleep disorders than men. The most surprising thing about the study is that, contrary to expectations, the quality of sleep is higher at advanced ages, or so we feel. "Even though older people sleep worse than younger ones, the perception of their own rest improves with age," said Michael Grandner, one of the authors of the work published in the journal Sleep .
