Facebook’s creator, Mark Zuckerberg , his engineering talents in a new direction — helping his wife Priscilla Chan get enough sleep.
Knowing Chan gets stressed when she’s aware of the time, Mark Zuckerberg built a wooden “sleep box” to gently let her know it’s time to get up, he revealed in a Saturday Instagram post.
The box sits on her nightstand and emits a soft glow between 6 and 7 a.m. — the time their daughters Maxima and August usually wake up. The light is faint enough that it won’t wake Chan, but visible enough to alert her to the time if she’s awake, so she’ll know one of them should go and check on the kids.

Being a mom is hard, and since we've had kids Priscilla has had a hard time sleeping through the night. She'll wake up and check the time on her phone to see if the kids might wake up soon, but then knowing the time stresses her out and she can't fall back asleep. So I worked on building her what I call the "sleep box". It sits on her nightstand, and between the hours of 6-7am it emits a very faint light — visible enough that if she sees it she'll know it's an okay time for one of us to get the kids, but faint enough that the light won't wake her up if she's still sleeping. And since it doesn't show the time, if she wakes up in the middle of the night, she knows to just go back to sleep without having to worry about what time it is. So far this has worked better than I expected and she can now sleep through the night. As an engineer, building a device to help my partner sleep better is one of the best ways I can think of to express my love and gratitude. A bunch of my friends have told me they'd want something like this, so I'm putting this out there in case another entrepreneur wants to run with this and build sleep boxes for more people!
Because the box doesn’t display the time, Chan can now fall back asleep without fear of sleeping too long. And the light is visible enough to let her know when its okay to wake up, but faint enough that it “won’t wake her up if she’s still sleeping,” Zuckerberg said.
The billionaire CEO said he shared his creation in case an entrepreneur wants to run with the idea and build the boxes for a larger audience.
“As an engineer, building a device to help my partner sleep better is one of the best ways I can think of to express my love and gratitude,” he wrote. “A bunch of my friends have told me they’d want something like this…”
