Screen time (/skriːn taɪm/) refers to the amount of time a person spends watching digital screens, such as televisions, computers, smartphones, and tablets. The term is often used in discussions about the health impacts of excessive use of digital media.
Etymology
The term "screen time" is a compound word, combining "screen" and "time". "Screen" in this context refers to the digital display of a device, while "time" refers to the duration spent. The term emerged in the late 20th century, coinciding with the rise of personal computing and digital media.
Health Impacts
Excessive screen time has been linked to a variety of health issues, including eye strain, sleep disorders, and obesity. It can also contribute to mental health problems, such as anxiety and depression.
Eye Strain
Eye strain or asthenopia is a condition characterized by tired or sore eyes due to intense use. It is commonly associated with prolonged screen time.
Sleep Disorders
Exposure to the blue light emitted by screens, especially before bedtime, can interfere with the body's circadian rhythm, leading to sleep disorders such as insomnia.
Obesity
Sedentary behavior, such as prolonged screen time, can contribute to obesity by reducing physical activity and increasing energy intake through snacking.
Mental Health
Excessive screen time, particularly on social media, can contribute to mental health issues, including anxiety and depression.
Management
Management of screen time often involves setting limits on the amount of time spent on screens, taking regular breaks, and ensuring a balance of physical activity and rest. There are also digital wellness tools available that can help monitor and manage screen time.
