Most every teenager nowadays uses their cellphone to text their friends and family. Texting can actually cause a lot of health drawbacks. Texting surprisingly causes bad posture which also leads to headaches, depression and heart disease. People who text too much can develop something called “computer vision syndrome”. This is when someone has been looking at a computer screen or phone screen for too long that their eyes get dry and vision gets blurry. The state did a test looking at teens test scores who use smartphones vs. teens who do not. After looking at the results, the teens who use smartphones had MUCH lower test scores.
