I get 6 hours of sleep a night, but is that enough? I asked a board-certified doctor — here’s what he said

A split screen showing an image of a woman wearing an Apple Watch sleeping and an image of an iPhone 15 displaying an average sleep duration of 6 hours and 11 minutes in the Health app. .

I recently started tracking my sleep with an Apple Watch, and it's told me something I already knew: I sleep for around six hours a night. While expert guidelines recommend that adults should sleep seven or more hours a night for optimal health, my sleep tracker consistently awards me high sleep scores.

So, does this mean six hours of sleep is enough?
