Puberty is a time of tremendous physical, emotional, and hormonal change. As children grow into teenagers, their bodies aren't the only things changing—their sleep patterns change, too.
Many parents notice that their once-early riser suddenly wants to stay up late, sleep in on weekends, and seems perpetually tired. It's easy to assume they're simply staying up too late by choice, but biology plays a much bigger role than many people realize.
During puberty, the body's internal clock shifts, making it naturally harder for teens to fall asleep early. At the same time, their developing brains and bodies continue to require plenty of sleep. This mismatch between biology and busy schedules is one reason sleep deprivation is so common during adolescence.
