How to limit your screen time
While electronic devices and apps are great tools for tracking food and wellness, too much screen use may cause a host of other negative side effects, from anxiety and depression to traffic accidents and even online addiction. “Most people have no idea how much time they’re spending online,” says David Greenfield, PhD, an assistant clinical professor of psychiatry at the University of Connecticut School of Medicine and the founder of the Center for Internet and Technology Addiction. “The goal is to create mindful technology use.”
Turn off all notifications
Research has found that social media usage releases dopamine into our brains and may elevate cortisol, leading to a compulsive pattern of use, similar to other addictions. “Reducing the number of notifications you have will decrease the likelihood that you will anticipate a reward. That’s what elevates those dopamine levels,” explains Dr. Greenfield, who is also the author of Virtual Addiction.
Focus on digital nutrition
Limit yourself to sites that add value to your life, says Kimberly Young, PsyD, a psychologist and founder of the Center for Internet Addiction in St. Bonaventure, New York. “When it comes to screen addiction, it is not about the volume of time but the quality of what we’re doing. I call it digital nutrition,” says Dr. Young. “It is very much like food—and making healthier choices about our screen use.”
Avoid combining screen time with food or meals
Research has shown a positive correlation between the increase in digital technology use over the past 20 years and an increase in the average weight of people under 30. “One of the things we know is that the more screen time you use, the more you’re going to weigh,” says Dr. Greenfield. “That doesn’t mean that the screen is causing your weight gain. What’s causing your weight gain is the increase in sedentary behaviour and the increase of unconscious eating because you’re distracted. So those two key features are happening simultaneously.” To avoid this unhealthy combination, never put electronic devices on the table when you eat. “Separate normal social interaction and self-care without the technology,” says Dr. Greenfield. When you go out to dinner, Dr. Young even suggests leaving your smartphone at home, if you are able.
Go on a digital fast
To put your real life and relationships back in focus, Dr. Young suggests doing a 48-hour digital detox. “You need to disconnect in order to reconnect,” she says. “We need to decompress from our devices.”
Never mix screens with sleep
The blue light emitted from electronic devices disrupts sleep by suppressing melatonin levels, a hormone the triggers the body’s sleep cycle. And poor sleep can lead to a variety of health problems, such as stress. Research has found that turning off devices at least two hours prior to bedtime allows the body to produce normal melatonin levels to achieve a restful night’s sleep. “Do not sleep with your smartphone next to your bed or under your pillow. Leave it charging in another room,” suggests Dr. Greenfield.
Monitor your digital time
Just as you reduce kilojoules to reduce weight, reduce the number of hours you spend online to reduce your screen time dependency, says Dr. Young, who discusses going on a “digital diet” in her popular TEDx talk. To eliminate the compulsion to check your devices, set specific times during the day to check email and social media, says Dr. Greenfield. “What happens is that people lose track of time when they’re on their devices, and they’ll compulsively check them over and over because the dynamic is changeable.” Use something like an app that times you, or write down when you start and stop. “It’s not unlike writing down what you eat,” says Dr. Greenfield. “What we’re trying to do is create a digital diet, so you don’t spend excessive amounts of time.”
