How come i always get really sleepy in the morning and afternoon but in the night i feel awake and not sleepy?

some people blame this on pure laziness. but i learned (and it was proven by scientists) that just because we're sleepy in the morning and we don't want to wake up, we're not lazy at all! it's actually based on our energy. every day, we have a certain time period when we have the most energy. "early birds" have most energy in the morning. if you're awake and hyper in the afternoon, that's when you reach the peak of your energy, and you're very active. don't worry.. most people, including me, hate mornings and are active in the afternoon at night! that's why even if you don't get much sleep in a day, you're still awake and active the following night! it's all about your energy sweetie. totally normal.
