What are the Causes of Anxiety (Based On Research)?

“An estimated 1.2 million children and youth in Canada are affected by mental illness,” (

Anxiety is very common in teenagers. Teenagers have many struggles that can be difficult to find proper solutions for. This can lead to stress, anxiety, depression, etc.

Internationally, around 1 in 3 adolescents experience an anxiety disorder ( In Canada alone, approximately 3% of youth experience anxiety (

Anxiety is most common to start occurring in the teenage years. This is because of all the stresses that are put on teenagers.

According to an online journal by Caroline Miller titled, How Anxiety Affects Teenagers, being anxious as a teenager is much different from anxiousness in younger children. The reasoning behind this is because younger children typically have fears such as fear of darkness, fear of monsters, etc.

Teenagers have more complex or elaborate fears such as worrying about themselves (their looks, their physical appeal, how well they do in something like school or sports, going through puberty before or after their friends, how others depict them as, etc.)


There are many common triggers of anxiety in teenagers. Every teenager is different; resulting in different causes and/or triggers of their mental illness. According to research, the most common triggers of anxiety in youth are school-related stress, social media and/or activity, perfectionism, and more.

1. School Stress

The most common trigger of anxiety in teenagers is school stress. Many students are stressed out at school because of high expectations from teachers or parents, peer pressure, schoolwork, and more. They may be overwhelmed with homework or overdue assignments, or maybe they are striving to succeed, which puts more pressure on them.

2. Social Media

Another common trigger of anxiety in teenagers is social media. Social media is a significant cause of anxiety; because teenagers are connected to it in many different ways. These may include connecting with friends, posting on media platforms, etc. Social media can be cruel and harsh which can result in lower self-esteem. Comments on posts, for example, can be overwhelming on teenagers because they may be negative and lead to cyber-bullying.

3. Social Activity

Social activity is a common trigger of anxiety in teenagers. Many teenagers prefer not to share or express their feelings. Socializing with friends, classmates, or acquaintances can lead to anxiety. Many teenagers are anti-social or get overwhelmed by conversing with others. This can lead to anxiety or stress.

4. Perfectionism

Perfectionism is a very common trigger of anxiety in teenagers. Many teenagers worry about not doing well in a school project or not winning a sports game. They strive to succeed, which puts a lot of weight on their shoulders.

Other common triggers or causes of anxiety include hormonal change, bullying, brain development, parental disapproval (family conflicts), depression, and intoxicating oneself with alcohol and/or drugs (


As mentioned previously, anxiety is very common to start in the teenage years. Many teenagers who have started to experience anxiety from certain causes may often be triggered by going to parties/sleepovers, going to camp or away from family, etc.

These triggers are based on research and the most common found in teenagers; however, everybody reacts differently to anxiety, and everybody has different triggers for it.

Anxiety comes in many different forms, some more serious than others. Anxiety is not to be taken lightly; it can lead to more serious problems such as panic attacks, depression, and/or social anxiety.

Some symptoms of anxiety or mental illness in teenagers are as follows:

- Constant fears and/or worries regarding everyday routines. - Regular irritability daily. - Consistent trouble concentrating. - Avoids social activity and/or engagement. - Sensitive to criticism and/or is self-conscious. - Frequent stomachaches and headaches.
