Sources of emotions and moods: time of day

Are you a morning person? Or do you feel best later in the day?

-People do vary in their moods by time of day. Levels of positive affect tend to peak in the late morning (between 10 am and noon) and then remain at that level until early evening (around 7 pm).

As for negative affect, most research suggests it fluctuates less than positive affect, but the general trend is for it to increase over the course of a day, so that it is lowest early in the morning and highest late in the evening.
