U. S. teens spend more than eight hours a day on screens, and there's growing concern over it. Now, a new study published by the American Psychological (心理的) Association, confirms that teens seem to feel better about themselves when they cut back.
"Social media can feel like a comparison trap (陷阱)," says study author Helen Thai, a doctoral student in psychology at McGill University. Her research found that limiting screen time to about one hour a day helped anxious teens and young adults feel better about their body image and their appearance. "What I noticed in social media was that I couldn't help but compare myself." Thai says. Reading posts from famous people and influencers, as well as people in her own social network, led to a lack of self-confidence.
So, Thai and a team of researchers decided to test whether reducing time on social media would improve body image. They gathered a few hundred volunteers, aged 17-25. all of whom had experienced symptoms (症状) of anxiety or depression — which could make them easily influenced by social media. Half of the volunteers were asked to reduce their social media to 60 minutes a day for three weeks. The other half continued to use social media with no limits.
The researchers gave the volunteers surveys at the beginning and end of the study, including statements such as "I'm pretty happy about the way I look," and "I am satisfied with my weight." Among the group that cut social media use, the overall score on appearance improved from 2.95 to 3.15 on a 5-point scale. The change may seem small, but any change in such a short period of time is worth noticing.
"It's encouraging that college students were willing to cut back screen time, even for three weeks," psychologist Andrea Graham says. While this study included people with symptoms of anxiety or depression, Graham says it's worth applying this approach to other groups, such as people with eating problems.
