One interesting thing that science has shown us is that the circadian rhythm (our bodies' natural clock cycle that determines when we sleep) is different for teenagers than younger children and adults.

You might wonder what a normal amount of sleep is or if you are getting enough sleep.ĭoctors and researchers recommend between seven and nine hours of sleep per night for adults.
