A study reveals that getting outside during the day can help people fall asleep more quickly and sleep more at night.
A recent University of Michigan study found, unsurprisingly, that getting outside during the day helps people fall asleep more quickly and get more sleep at night. Indoor light isn’t quite as helpful as actual sunlight.
The Center for Disease Control and Prevention generally recommends removing all devices from the bedroom to get a better night’s rest, but a smartphone app created by the University of Michigan is helping to illuminate how people sleep around the world.
Back in 2014, a group of researchers from the university released a free app for iOS and Android called Entrain to help travelers get over jetlag faster by monitoring users’ circadian rhythms and then advising them when to change the light in their environment to aid in the adjustment to a new time zone. During the first year in the app store, 8,070 users sent in their results.
Study authors mathematics professor Daniel Forger, assistant professor Amy Cochran and graduate student Olivia Walch found that the average minimum sleep duration ranged from seven hours and 24 minutes in countries such as Japan and Singapore to a maximum average duration of eight hours and 12 minutes in the Netherlands. The average sleep duration for U.S. residents was 7.87 hours.
