As previously discussed, sleep and screen time are heavily impacted by the other and can lead to affecting one's behavior as well. If someone does not get an adequate amount of sleep, it can affect their behavior and performance for the day.[18] High amounts of screen time also can significantly affect a person's mental health. With screen usage increasing as time progresses, adults have begun spending more and more time focusing their attention of screens.[35] This time spent sitting and viewing a screen has been linked to mental health effects such as anxiety and depression.[35] Adults who spend six hours or greater using screen time are more likely to suffer from moderate to severe depression.[36] This increased use in screen time has been shown to be directly correlated with an increased chance of depression in adults.[36] With this added risk, lack of sleep plays a major role in a healthy mindset, and without proper rest, mental health can degrade at a higher rate.
