Why Are Teens So Moody?

Being a teen can be an amazing time of discovery,
learning, and friendship, but it’s also a time of rapid change, and emotional highs
and lows where things can feel really ‘tough’. So, what’s going on in our brains and bodies
that makes us feel this way? Why is being a teen so hard? We’re often told that the most important
years of brain development are between 0-5, although recent research has found adolescent
development to be equally important. During childhood, our brains continually grow, generating
grey matter until they reach their maximum size, which for girls is around age 12 and
boys around age 14. But even after this, the brain works to become more efficient by cutting
away unused grey matter that isn’t ‘exercised’ by experience, and at the same time increasing
myelin – fatty tissue that insulates brain pathways. Puberty begins in the hypothalamus, where
a protein called kisspeptin is produced, triggering the pituitary gland to unleash the hormones
testosterone, estrogen and progesterone. These activate the ovaries and testes, but also
cause you to seek emotionally charged experiences – whether it’s a movie to make you sob,
or driving 180 km/h down the freeway. It causes your response to emotionally loaded images
or sounds to be more intense, which is why listening to One Direction may produce large
bouts of the feels. The area of the brain responsible for planning
ahead and assessing risk is still immature in teenagers. Which is why teens are more
likely to participate in high risk behaviour like unprotected sex and drinking and driving.
Interestingly, in a simulated driving experience, adults and teens took the same amount of driving
risks while alone; however, when surrounded by an audience of friends, teens took significantly
more risks while adults were unaffected. What’s the benefit of this behaviour? Peer acceptance. In a study where teens were asked to rank
music clips with and without knowing what their peers picked, their choices changed.
Unlike small children and adults, feeling socially isolated as a teen creates feelings
of intense unworthiness. This along with our biology can contribute to teens prioritizing
friends over even family. As social animals, stepping outside the safety of our family
creates genetically diverse populations, diminishing the likliness of inbreeding. In fact, teens
have heightened social abilities like processing and evaluating facial expressions better than
other age groups, allowing teens to be extremely cognisant of friends joy, sadness, or stress. Speaking of stress, the hormone released in
stressful situations to help sooth the brain cells of children and adults has the
opposite impact on teens, causing an increase in anxiety. Pair that with a change in circadian
rhythms making you to want to wake three to four hours later than adults, it’s no wonder
some people describe teens as emotionally ‘moody’. On the other hand, teens are very physically
healthy. The immune system is highly functioning, teens have increased tolerance to temperature
changes and a high resistance to cancer. But despite physical fitness, records show that
death rates increase by 200-300% after childhood due to motor vehicle accidents, homicide and
suicide. Several mental illnesses emerge, during adolescence such as anxiety, depression
and eating disorders. Scientists believe that the many changes in white matter, grey matter,
and connections in the brain may be to blame, with an increased risk of errors during this
time. But with a greater number of synaptic connections,
and increased plasticity, the teenage brain is primed to learn quickly and memorize content
fast. Unlike an older brain, rooted in what it knows, teens can respond easily to their
environment and make incredible strides in communication and socialization. Not to mention
being passionate is incredibly valuable and taking risks is often what is needed to make
changes in your life and the lives of others – being a teen can be tough, but it can also
be amazing. If you want to know why teens are the biggest

    Teens and adults are nearly the same size and but kids are aay shorter so kids dont see run over dogs or cats when going for a ride in the car because they are short but teens and adults are tall enough to see run over dogs and cats and thats what makes them sad or depressed by a bit

  10. "teens are very physically healthy"
    I'm a teen, and not many teens I know are "very physically healthy"

  11. This comment section is full of teens trying to explain why they’re moody, yet only real furthering the video’s point.

  12. Your hormones cause that shit.hormones are very active when you are a teenager,because of them your personality completely changed,during that process you are easily pissed off,you have feelings for opposite genders, and at last you are becoming a man.or a woman

  13. Lmao im not moody im cold hearted and the only thing i experienced in "puberty" is voicecrack and growing very small beard, no emotions

  14. why are there so many edgy teens here??? You’re just moody damn you aren’t depressed because you listen to billie eillish

  15. For people saying social media is the biggest reason, yes, you are Technically right but not really. Because back then teens used to grow up and live with their surroundings only, and those surroundings are usually people who live quite similarly to each other, so they think that's the norm and they live with it without having to think about it too much. While on the other hand Now, the vast majority of teens nowadays are exposed to the rest of the world, and on social media they most likely are exposed to wealthier, better living people. And on places like Youtube they most probably see the worst of the worst of this planet, so they start thinking about it way too much and questioning everything, and they get in this cycle of asking "why". So to sum it all up, they know more (not necessarily better) than the previous ones. And to sum it up even more, Overthinking.

  16. Hey make a video on why are early bloomers are "depressed" and real moody so much they hate their loved ones

  17. I don’t understand, I’ve never been moody. Also I’m not in a rush to grow up and I’ve never felt awkward or anything.
    Then again, I’m eight, emotionally. I sleep with a teddy bear and I love playing with toys. Something is wrong with me I think.

  18. When I was a teenager I just played video games, studied, was being lonely, dealing whit anxiety and hormones hehe my teen life in a nutshell.

  19. my parents always tell me to smile more. it actually annoys me. it’s impossible to do 😁 when you feel 😡😭🤕🤒😔😡

  20. I'm thirteen and I hate when people say your just acting like a normal teenager you'll get through it because the thing is I've been acting the same way sense I was five mostly because my mom and dad always faught so then me and my mom moved away and she used to give me so much attention because I was the only child and she was a stay at home mom but then she started going to college and partys and stuff and I started kindergarten so we didn't spend much time together anymore so the way I got attention was by flipping out and swearing and being mean to people but then my mom would just get mad and like yell at me and hit me so then it would make me more mad and I would do it more but then it continued and as it continued it got worse it's not just a teenage fase and I'm sorry for going on a rant it just helps when feeding the dog u knwo.
