Mark Zuckerberg builds a glowing wooden box to help his wife sleep better

Facebook's Mark Zuckerberg built a glowing wooden box to help his wife, Dr. Priscilla Chan, sleep better. 

According to Mark Zuckerberg, the glowing wooden box will help his wife Priscilla sleep better through the night without having to check her phone to see if it's time to look over their children. 

The "sleep box" emits a very faint light between 6 am and 7 am - when their daughters are expected to wake up.

It doesn't show the time, as that would stress her and disrupt her sleep, the Facebook chief executive officer said in an Instagram post on Saturday (April 27).

"So far this has worked better than I expected and she can now sleep through the night," Mr Zuckerberg said, adding that the device is already popular with his friends.

"I'm putting this out there in case another entrepreneur wants to run with this and build sleep boxes for more people!"
