Morning People / Night People

Each person has his or her own circadian rhythm. Some individuals are morning people while others are night people. There are quite a few differences between morning people and night people. One difference is the sleeping time. Moring people follow the maxim of “early to bed, early to rise,” and turn in by 9:00 pm. Night people only get five or six hours of sleep a day. A second difference is the brains excitable time. Morning people's brains were most excitable at 9 a.m. This slowly decreased through the day. In contrast, for night people, whose brains were most excitable at 9 p.m. For example, morning people are ready to face the day while having a cup of coffee at the breakfast table. However, night people are often tired and cranky at the breakfast table, they feel that they function better at night and are often very productive during the evening hours. All in all, though there are differences between the morning people and the night people, we understand that sufficient sleep is very important no matter which kinds of people you are.
