Consumer electronics company Withings released an analysis of user behavior around last year’s Daylight Saving Time “fall back” clock adjustment to explore how it impacts Americans’ sleep and what they do with that extra hour. It was expected that Americans would use the extra hour to catch up on sleep; however, Withings data showed that sleep duration increased by only 27 minutes on average.
According to nonidentified and aggregated data collected from September 2013 to August 2014 from a sample of 10,000 Withings Pulse 02 users, there was no significant difference in the time Americans went to sleep on the night the clocks change, yet users woke up an average of 29 minutes earlier on the following morning than other Sundays in October. Although we gain an extra hour, only 27 minutes are spent as extra time asleep. The remaining 35 minutes are added as time to enjoy a longer day. Surprisingly, there was no significant difference in the time Americans went to sleep, indicating that people did not use this extra hour to stay out later on Saturday night.
“The Withings sleep study around Daylight Saving Time shows just one piece of information that is only now accessible with sleep tracking sleep devices, such as the Pulse 02 and Aura, and with the consumer adoption of precise sensors that can track subtle activity like sleep,” says Withings CEO Cédric Hutchings in a release. “Understanding sleep patterns and certain events that both positively and negatively affect our sleeping behaviors are the first steps in helping to bring sleep to the forefront of the health conversation.”
