Body dysmorphic disorder is defined by MayoClinic as a mental health disorder in which you can’t stop thinking about one or more perceived defects or flaws in your appearance — a flaw that appears minor or can’t be seen by others. But you may feel so embarrassed, ashamed and anxious that you may avoid many social situations.

As defined by Psychology Today, Dopamine is known as the feel-good neurotransmitter—a chemical that ferries information between neurons. The brain releases dopamine when we eat food that we crave, contributing to feelings of pleasure and satisfaction as part of the reward system. This important neurochemical boosts mood, motivation, and attention, and helps regulate movement, learning, and emotional responses.

The fear of missing out. You see a friend hanging out with other friends on social media without you and immediately feel left out. This can fuel social media addiction because you continuously check up on your friends to see what they are doing without you.

Also called the slot machine effect. Max Stossel of Center for Humane Tech describes variable rewards as one of the most addictive mechanisms in the brain. Think of it this way; sometimes you pull a lever or push a button and as a result, sometimes you get a reward and sometimes you don’t. The unpredictability is what fuels the addiction and keeps people playing the game.

Social media has a similar function. The continuous scrolling acts as your own personal slot machine, where you don’t know what reward comes next.
