A study in Nature Communications has found that people tend to sleep the least from early 30s to early 50s.
The research was carried out by UCL, the University of East Anglia, and the University of Lyon.
More than 700,000 participants from around 63 countries took part in the study.
“Here, using reported sleep duration from 730,187 participants across 63 countries, we find three distinct phases in the adult human life-course: early adulthood (19-33yrs), mid-adulthood (34-53yrs), and late adulthood (54+yrs),” the journal report reads.
“Although previous studies have also shown a non-linear association of sleep duration with age, here we reveal three distinct phases in the life-course where reported sleep duration changes at an approximately monotonic rate during each period.”
