Longer sleep duration was correlated with same-day higher sleep quality.
Higher sleep quality predicted higher positive affect and lower negative affect on the next day.

Higher positive affect predicted higher sleep quality and a greater likelihood of MVPA on the following day.
Previous-day MVPA predicted higher next-day negative affect.

Getting good sleep can make you feel happier and more active during the day.
