The creators of Pokémon GO want you to play the game at all hours, but without sacrificing precious sleep.

The Pokémon Company CEO Tsunekazu Ishihara announced at a recent press conference that they will "turn sleep into entertainment." Niantic CEO John Hanke followed Ishihara to expand slightly on the topic, stating, "We’re excited to find ways to reward good sleep habits in Pokémon GO as part of a healthy lifestyle."

As yet, we don't know exactly what this means, but a new device called device called Pokémon GO Plus+ might provide a clue. Developed in conjunction with a new app called Pokémon Sleep, which "tracks a user’s time sleeping and brings a gameplay experience unlike any other," Pokémon GO Plus+ can be used night and day.

Expanding on the original device, which functions similarly to a smart watch in that it lets you play certain aspects of the game without taking your phone out, the upgraded version also has an accelerometer, which monitors sleep when placed on the bed next to the pillow.

Pokémon Sleep is coming sometime in 2020.
