Study suggests sleep varies by age, geographical location, gender
Even after sleeping for 8 hours a day, do you feel sleep deprived and yawn the whole day? A new study has found the answer to your question.
The study suggests that the duration and timing of sleep vary in individuals depending on their age, gender and region where they live.
It was interesting to find that the circadian rhythm shifts later even in people over 20 years of age. It was already previously known that sleep timing is delayed in adolescence. What was clearly highlighted in this study is how long into adulthood this actually carries on, said a researcher.
People in Europe and North America slept the longest, while the shortest sleep was observed in Asian countries. Sleep was times the latest in the Middle East, while the earliest sleep rhythm was found in Oceania.
Young women slept more than young men, and the former also went to sleep earlier.
Geographical differences were relatively small but similar to those seen in prior, smaller-scale studies. The need for sleep does not vary greatly between cultures, but differences arise in terms of the time reserved for sleeping, noted a researcher.
In the study, the sleeping habits of more than 17,000 adolescents and young adults were monitored for 2 weeks.
The monitoring was carried out with the help of Polar Electro devices worn by the study subjects, measuring sleep with accelerometers, among other technologies.
The subjects gave consent for using their personal data for research purposes, with the data being processed in anonymized form.
We gained an exceptionally diverse and extensive dataset which provides important basic knowledge on sleep among different age groups across the globe. Validated consumer devices may hold the potential for investigations more comprehensive than those conducted with conventional data collection methods, said the researcher.
