The New York Knicks player discusses how lack of sleep after his child was born affected his performance at the sport, reports ESPN.

β€œIt can affect quantitative performance and physical performance,” says Dr. Ana Krieger, the Medical Director of the Weill Cornell Center for Sleep Medicine. β€œYour speed and accuracy and reaction time are heavily dependent on adequate sleep. So if [someone] is not sleeping the proper amount or having the quality [of sleep] required during the night, all of the neurological functions are affected.”

Smith can attest to this. He estimates he was getting about five or six hours of sleep per night after Ella was born.
