Any teacher would feel insulted if their students fell asleep while teaching. A teacher would believe that their students don’t care about their class. While teachers might be right on some level, it isn’t always personal. You see, teenagers need around 8-9 hours of sleep.

Most teens don’t get enough sleep these days, and as a result, are sleep-deprived. This will negatively impact their emotions, learning, obesity, and driving skills. Reasons for why students are sleep-deprived aren’t as cut and dry as teachers and parents think. 1

Early school Times

The circadian rhythm is controlled by the hypothalamus in the brain. In short, the circadian rhythm signals your brain when it’s time to go to sleep. This changes when a child reaches puberty, as they won’t feel tired at their usual bedtime. For example, a teen who just reached puberty won’t feel sleepy at 8:00 pm like they used to, but will now feel sleepy at 11:00 pm. 2

Social Media

Controversial to some, social media helps to chat with friends and family. Yet phones emit a blue light that can trick your circadian rhythm into thinking it’s still daytime. Additionally, students might be tempted to constantly check their social media accounts for comments or likes. 3

Homework

It’s common for a student to stay past their bedtime to catch up on their homework. Their homework can be reading a book, working on a project, or studying, all of which can take a long time to complete. Because of this, it’s common for teens to feel overwhelmed, stressed out, and then miss sleep. 4
