Forget birds chirping or sun streaming in. Dwayne “The Rock” Johnson released a whole new wake up experience yesterday.
The motivational alarm clock app -- “The Rock Clock” -- lets you wake up to the sound of Johnson barking orders, playing the guitar or imitating a classic alarm's “BEEP, BEEP, BEEP, BEEP…”
“Yes, that’s me really singing and playing guitar to wake your ass up,” Johnson shared on Instagram yesterday announcing the clock’s launch.
Upon downloading the app (available for iPhone via iTunes or for Android via Google Play), users are prompted to set a goal. A few preset suggestions include “gain five pounds of muscle,” “learn a new language" or "eat more green stuff."
Johnson says he will track your goals and you'll get to track his too: "I'll be shouting you guys out personally via video messages on this app, so let's chase our greatness, get after it and as always have some fun along the way,” Johnson wrote in his Instagram announcement.
You can also put the app on “Rock Time,” which syncs you with Johnson’s schedule. (NB: we don't recommend this if you'd like to sleep past 4:45 a.m.)
Could the Rock really improve your sleep?
So will “Rock Time” actually improve your sleep? It's relevant to point out that the alarm is still an app, meaning you'll have to keep your phone in the bedroom. If you find it too tempting to use your smartphone before you turn in for the night, this may not be the program for you.
After all, the blue light from your device could disrupt your sleep in all sorts of ways, from prolonging how long it takes you to fall asleep to delaying your circadian clock to suppressing your body's levels of the sleep-promoting hormone melatonin to reducing and delaying your REM cycles.
We touched base with sleep expert Neil Kline, a sleep physician and director of the American Sleep Association, who (not surprisingly) said there’s scant evidence to suggest syncing up to Johnson’s body clock is going to do yours any good -- or if his voice is any better to get you out of bed than any other alarm tone.
One thing the alarm gets right is that it has NO SNOOZE function, Kline said. The Verge reported that Johnson doesn’t believe in snoozing. And Kline says Johnson is on to something.
“The quality of sleep between alarm snoozes is low. After waking up to push the snooze button, it takes time to resume quality deep sleep,” Kline said. So you should be setting your alarm for the latest time you can afford to sleep.
And ultimately, if Johnson's chainsaw ring tone gets you out of bed, there's no harm in trying it out. Whatever works, right?
