42 Overly-Emotional Facts About Adolescence

Penelope Singh

Whether we’d rather forget or not, we all remember being a teenager. They might have been the best years of our lives—full of homecoming dances, first kisses, and fast friends—or the worst—complete with zits, calculus, and unrequited love—or maybe a bit of both. One thing is for sure, though: we were a whole lot different then than we are now. Whether you’ve made it through these years, have a teenager of your own, or are even still a teenager yourself, take a look at these 42 overly-emotional facts about adolescence.

Adolescence Facts

42. What’s My Age Again


“Adolescence” is typically defined as the years between 11 and 19.

41. Inside and Out

Just as we go through physical growth spurts and growing pains during our teenage years, our brain goes through the same things—and the results can be equally as awkward. Sheryl Feinstein, author of Inside the Teenage Brain, argues that, like growth spurts, “new cognitive skills and competencies may come in leaps and stutters” during our teenage years.

40. Ch-Ch-Changes

What constitutes physical adolescence? Pubescent years tend to be characterized by a growth spurt, bone growth and mineralization, weight changes, the development of the cardiovascular system, and, particularly for boys, an increase in strength and endurance.

39. Spring Cleaning

Researchers used to believe that as infants—and only as infants—we start out with an excess of neural connections in our brains, connections that then get pruned away in our first years of life to become more efficient pathways. In 1999, however, scientists proved that there is a second burst of pruning just before adolescence, when girls are 11 and boys are 12.


38. Get ‘Em While They’re Young

This discovery also leads to the “use it or lose it” theory of neuroscience. That is, the activities and thought patterns that we use most are kept and strengthened during this pruning process, while the activities we practice the least have their neural connections pruned for greater efficiency. Basically, this means if you want your kid to be a really good violin player, you better start them young. Although this pruning process continues until about the age of 25, with smaller changes throughout our lives, starting these activities young means stronger neural connections for these practices as an adult.

37. Arrested Development

Our brains don’t fully develop until the age of 20 for girls, and as late as 25 for boys. That means that even during high school graduation, when you think you’ve finally become an adult—well, you haven’t. You can still buy a lotto ticket or join the army, though.

36. Blame it on the Brain

Teenage brains rely more on the limbic system (the emotional part of the brain) than adults, who rely more on the rational prefrontal cortex, which means teens’ decision making processes can be overly influenced by their passions. Teenagers are overly emotional? You don’t say.

35. Guinea Pigs

In adolescence, we start to figure out social behaviors and abstract thought, but we’re not very good at those things yet. As a result, teenagers often use their parents as guinea pigs to find out their boundaries, which often leads to parent-teenager conflict. Feinstein advises to make sure to stay calm during these fights.

34. Seriously, Don’t Nag Me

A 2015 study from the Universities of Pittsburgh, Berkeley, and Harvard recently monitored 32 teens, and found that teenage brains actually stop listening when being lectured. The study placed the teens under a brain scanner while a recording of their mother nitpicking them played, and researchers watched as key areas of the teen’s brain shut down when listening to criticism. So our mom were right: we really don’t listen to them.

33. Don’t Think Too Much

According to a 2004 study by the Annals of the New York Academy of Sciences, as teens become better at thinking abstractly, their social anxiety increases. If you can think abstractly, you start to think more about what others think of you. Well, great.


32. Risky Business

A 2014 study argued that teenage brains are wired to seek reward, whether monetary or otherwise. Because of this, teens are vulnerable to risk-taking behaviors like engaging in illicit activities, jumping into unsafe water, and getting into fights. Also stealing their father’s favorite, very expensive, scotch. Just me?

31. Just Say No to Mom and Dad

Studies show that teenagers who argue and talk back to their parents may actually be in a better position than those who don’t. Lippy teens who openly disagree with their parents are also more likely to say “no” to peer pressure, and can often avoid the above-mentioned risky behaviors.

30. Cool Moms

Even though teenagers get into conflicts with their parents, parents are still an integral part of teen lives. A survey run by Feinstein revealed that 84% of teenagers think highly of their mothers and 89% think highly of their fathers.

29. Nap Time

Yeah, yeah, they never want to go to school in the morning. But guess what? Teenagers do need more sleep than adults: about 9-10 consecutive hours a night. Thing is, teenagers tend not to get this much sleep, as their circadian rhythms are in flux, leading to late nights.

28. Sleep In

In addition to needing more sleep, teenagers’ brains are also wired to sleep later. Even just a half hour helps: one study showed that when school was delayed from 8:00 am to 8:30, the students had better moods, motivation, and attendance records.

27. Self-Centered

There’s a scientific reason for why teens seem so self-absorbed: hormone changes in the adolescent brain increase levels of oxytocin, which has been linked to feelings of self-consciousness and the sense that everyone is watching you. These feelings reach their apex when the teens are 15 years old.


26. Down Side

This self-consciousness also leads to self-esteem issues. In high school, for example, 44% of girls and 15% percent of boys are trying to lose weight, and 70% of girls between 15 and 17 avoid everyday activities like going to school because they are self-conscious about their appearance.

25. Bulking Up

Boys’ self-esteem issues usually manifest in bulking up: over 40% of boys in middle school and high school exercise in order to increase muscle mass. 38% of boys in these ages also use protein supplements, while 6% reported using steroids.

24. Feeling Blue

Around 20% of adolescents will deal with depression before becoming adults.

23. I Wish

The number one wish of teenage girls isn’t that Edward Cullen was a real-life vampire, it’s that their parents would communicate better with them.

22. Teen Mom

Approximately 750,000 teenagers in the US become pregnant each year; something like 82% of these pregnancies are unplanned.

21. French Kiss

European teenagers, however, are more likely to use birth control and, when they use it, to use more effective birth control; European teen pregnancy rates are lower on average than in the US.


20. Born This Way

In the years 2006-2008, 3% of boys and 8% of girls identified as homosexual or bisexual.

19. Sweet 17

On average, teenagers have sex for the first time at the age of 17.

18. Straight A’s

Some good news for worried parents: According to the American Psychological Association, sexually active teenagers in committed relationships don’t see their grades decline due to any preoccupations with young love.

17.  Don’t Keep it Casual

However, if a teen is engaging in regular, casual hook-ups, this behavior is associated with declining school performance.

16. I Wanna Be Popular

Where do bullies come from? Well, prepare to have all your high school resentment validated: the popular kids. A 2011 paper published in the American Psychological Review found that “the more central you are to your school’s social network, the more aggressive you are.” Well, well, well.

15. Preventable

The majority of teen deaths (72%) are preventable, and arise from car accidents, unintentional injuries, homicide, and suicide.

14. Pushed Around

A 2010 study showed that about 2.7 million students were victims of bullying in the US, which amounts to about 282,000 high school students being bullied each month.

13. No Safe Space

Most bullying occurs at school, with 74% of male bullying victims and 55% of female victims reporting that it happens during school hours. However, 43% of girls who have been bullied say that the bullying happens online.

12. Think About Your Future

Teens are investing in their future, particularly teenage girls. Although 26% of boys are saving up for what the future holds, and 5% of boys are tucking away money for college, in comparison, 46% of girls are saving for the future, and 27% of girls are saving for post-secondary education. Reach for the stars, teens.

11. Addicted

Teenagers spend up to nine hours a day looking at social media, news media, and other online content. Parents, however, think their children spend a mere two hours online.

10. Liar, Liar

Although 50% of parents think their kid is open to them about what they’re doing online, 44% of teenagers visit websites their parents don’t want them surfing, and 23% of these adolescents lie about doing so.

9. Unfriended

Maybe the biggest online surprise? Teens aren’t going on Facebook with their nine hours of surf time. Global Web Index’s 2014 study discovered that 50% of teenagers are using Facebook less than before: teens claim the site is boring and not private enough.

8. E-fail

In fact, teenagers are using the Internet completely differently from most adults: many of them don’t have email. ComScore’s 2010 Digital Year in Review showed that email use between people aged 12-17 dropped 59%, and many teenagers are using social media to communicate instead.

7. Be Your Own Role Model

It’s not all doom and gloom for teenagers: youth violence is down from half of what it was 20 years ago. Surprise! The good old days were not that good.

6. Nuclear Family

The size of teenagers’ families is shrinking from earlier generations: today, 45% of teenagers have only one or no siblings, and one in three teenagers has one parent or divorced or separated parents. At least these teens will never have to know what it’s like to share a bedroom with a sibling (still bitter about that).

5. Underage Drinking

41% of teenagers say they have been drunk, and the average age they had their first drink was 14. 99% of teenagers say it’s okay to drink alcohol occasionally.

4. A Generational Problem

Teenagers aren’t into picking up every vice they can get their hands on, however: only 12% of adolescents smoke, and eight in 10 teens would like their parents to stop smoking.

3. They’re Not Always on the Internet

Teenagers like to—and have the time to!—read. In a survey taken in Germany in 2016, 47% of teenagers between 12 and 13 read books daily or several times a week. Thank you, Harry Potter! Just don’t ask them to read a math textbook.

2. Community Service

Although it also looks good on a college application, 81% of teens say they would volunteer their time to help others. Hey, if you can kill two birds with one stone, go for it.

1. Aunt Flo

Due to nutritional and environmental influences, girls reach puberty earlier now than they used to. In 1900, for example, the average age for the onset of menstruation was 15, but by the 1990s, this had dropped to 12.5
