Technology use may increase the risk of physical issues as well, including:
Eyestrain
Technologies, such as handheld tablets, smartphones, and computers, can hold a person’s attention for long periods, which may lead to eyestrain.
Symptoms of digital eyestrain can include dry, tired eyes and a headache. Taking regular breaks away from the screen may reduce the likelihood of this issue.
Anyone regularly experiencing these symptoms needs to consult an optometrist for a checkup.
The 20-20-20 rule for digital viewing
The American Optometric Association recommends using the 20-20-20 rule when using any form of digital screen for longer periods of time.
To apply the rule, after every 20 minutes of screen time, a person needs to take a 20-second break to look at something at least 20 feet away.
Doing this may help reduce the strain on the eyes from staring at a screen for a continuous period.
Sleep problems
Using technology close to bedtime or during the night may interfere with sleep.
A 2021 study of young adults found that cellphone use before bed predicted difficulty sleeping. The effect was more pronounced when participants used their phones to look at emotionally-charged content.
Gentle activities to wind down, such as reading a book, doing gentle stretches, or taking a bath, can be suitable alternatives.
Changes in physical activity
Modern technologies often encourage people to be more sedentary while they watch television, play games, or use the internet. Research from 2020 has shown an association between using electronic devices and increased time spent sitting, which can have harmful long-term effects.
However, it is also true that technology can help people exercise.
For example, during the COVID-19 pandemic, a 2021 study notes that many individuals used fitness apps and trackers to find motivation to exercise. Indoor exercise equipment helped people continue their workouts, while some took up new forms of exercise using online tutorials.
