Young late nighters are less physically active and fit than their early bird counterparts, suggests new research from Australia.

“Late bedtimes and late wake-up times are associated with an unfavorable activity and weight status profile, independent of age, sex, household income, geographical remoteness, and sleep duration,” reads the abstract of the study, which was published in the journal SLEEP on Oct. 1.

A team of scientists from Adelaide studied a total of 2,200 Australian adolescents, aged 9 to 16 years old, using time interviews and pedometers.

Despite similar sleep durations, late-rising and late-sleeping adolescents were observed to undertake 27 minutes less daily physical activity than the early risers and early sleepers, who went to bed 70 to 90 minutes earlier and woke up 60 to 80 minutes earlier.

“The children who went to bed late and woke up late, and the children who went to bed early and woke up early got virtually the same amount of sleep in total,” said study co-author Carol Maher from the University of South Australia in a press release.

“Scientists have realized in recent years that children who get less sleep tend to do worse on a variety of health outcomes, including the risk of being overweight and obese. Our study suggests that the timing of sleep is even more important.”
