"Snoring Managers at Work" Are Universal... Age Group with the Shortest Sleep Time

Average Sleep Duration Worldwide 7.01 Hours
Shortest Between Ages 33 and 53
"Due to Balancing Childcare and Work," Analysis Shows

The sleep duration of people worldwide was found to be shortest between the early 30s and early 50s, a period focused on childcare and work.

On the 29th (local time), according to Science Daily, a research team led by Professor Hugo Spears of Psychology and Linguistics at University College London (UCL) and Professor Antoine Courtrot of Cognitive and Behavioral Sciences at the University of Lyon in France announced the results of an analysis of lifetime sleep pattern changes and national differences based on data from 731,087 people across 63 countries.

The average daily sleep duration worldwide was 7.01 hours. Women slept longer than men, averaging 7.5 hours.

Sleep duration was longest among the youngest individuals (at least 19 years old).

It gradually shortened from the 20s to early 30s, reached its shortest point between ages 33 and 53 during a lifetime, and then began to lengthen again.

This trend was independent of gender, country, or education level differences.

Regarding the reason for the reduction in sleep duration during half of a lifetime, the research team explained it was likely due to "childcare and work life."

The study results were published in the latest issue of the UK scientific journal Nature Communications.
