Too much TikTok can be harmful to brain development.
TikTok is a popular social media platform that is known for its short videos. The maximum length for a video is now 10 minutes, but many of them are only a few seconds long. Experts fear that the short style of TikTok videos is leading to an effect called the “TikTok brain.”
When we watch videos with content that we find interesting, the reward centers of the brain are activated. Our brain releases a chemical called dopamine, which we also get from activities like exercising and listening to music. This creates feelings of pleasure that we want to repeat again and again. Many TikTok users show signs of addiction when watching the short and interesting clips. It can be very difficult for them to stop watching these short videos, even when they have something more important to do. This behavior trains the brain to expect instant satisfaction, thus making people's attention spans shorter in the long run.
TikTok is a fun way to kill time, but developinga TikTok brain is not good. To deal with this problem, the platform has created features that help parents manage their children's usage. Users should be conscious ofhow long they spend on TikTok and remember to take breaks from the app regularly.
