Did you know This Study Shows What Happens to Your Brain If You Ditch Your Smartphone for 72 Hours
Mobile usage has become common in today's world, but a study published in Computers in Human Behavior found that
not using a smartphone for 72 hours can change our brain activity in
areas which are linked to self-control and reward. Researchers wanted to
know how short breaks from smartphones can change our brain functioning
because too much smartphone use shares similarities between gaming
addiction and substance use. There had been some studies done which
talked about differences between light and heavy smartphone users, but
this study wanted to know how short-term restriction of smartphones can
affect our brain activity.
For the study, the researchers
recruited 25 young adults between the ages of 18 and 30 who were regular
smartphone users. They were also examined for any mental health
conditions or gaming addiction. The study made participants grow through
a brain scan called functional magnetic resonance imaging in two
sessions. The participants were asked to fill a questionnaire about
their smartphone usage habits before the first scan. When the first
brain scan was done, they were asked to restrict their smartphone use
completely for the next 72 hours.
After 72 hours, participants
returned for a second brain scan and again filled a questionnaire about
their moods and smartphone cravings. Participants were also shown some
blocks of images to monitor responses of their brains to smartphone
cues. Some of the blocks contained images of everyday objects, some were
pictures of turned off smartphones, and some were pictures of turned on
smartphones. The researchers then analyzed the data of first and second
scans. They focused on brain regions which were related to attention
and reward processing.
The
results of the questionnaire, which the participants were asked to
fill, didn't show any significant differences before and after 72 hours.
But on the other hand, the brain scans showed significant differences.
The scans, while seeing the smartphone images (turned off and turned
on), showed increased activity in the nucleus accumbens and anterior
cingulate cortex, which wasn't there when participants saw images of
everyday objects.
The activity observed when participants saw
images of smartphones was similar to studies related to substance
craving, which suggests that smartphone usage works in a similar way.
The study also found a connection between activity in the parietal
cortex and craving which suggests that this brain region may influence
the urge to use smartphones. The researchers say that even a short break
from smartphones can alter the brain activity, but these changes are
mostly neural and not behavioral. There are some other limitations to
the study, too, like it only focuses on short-term effects and not
long-term.
