We're Not Sleeping Enough
According to the National Sleep Foundation, adults age 26 to 64 require seven to nine hours of sleep each night. (Nine hours – that would be amazing!) According to a 2013 Gallup poll, 40 percent of Americans get less than seven hours of sleep a night, with 14 percent getting five hours or less [source: Jones]. That explains the line at Starbucks.
One of the most alluring promises of wearable technology is that these wrist-bound gadgets can actually help us sleep more and sleep better. Movement trackers like Sony Smartband and UP from Jawbone pair with smartphone apps to decode your sleep patterns. Are you getting enough deep-sleep REM cycles every night? Are you waking up at the wrong time? Are you going to sleep too late?
Once the apps diagnose your sleep issues, they can help you solve them by sending you reminders to shut off all electronics a half hour before bedtime, or even pair up with a smart thermostat like Nest to adjust the air temperature to match your sleep cycle.
