using social media too much will have a serious impact on health. Because the young are addicted to social media, they will go to bed late to read news on Facebook or chat with friends. Staying up late is really harmful to the health, especially, the brain. If the young do not sleep enough, their health will be affected seriously by losing weight or always feeling tired. Their brains also will not work effectively and they will be in sleepy condition. Moreover, addiction to social media can cause depression in the young. When the young use social media, they will see other people on social media. If the young see other people who are better than them in appearance or talent, they can feel inferior.
