College students in search of a good night's sleep may
want to put some distance between their pillow and their cell phone, new
research suggests.
However, study author Karla Klein Murdock, a
professor of psychology at Washington and Lee University in Lexington,
Va., took pains to make clear that her work does not draw a direct
cause-and-effect between more texting and worse sleep, only an apparent
association.
But the research did reveal that whether or not a
student was experiencing stress, greater texting frequency correlated
with key indicators of sleep trouble. That, she noted, took the form of
sleeping less, taking longer to fall asleep, spending less time actually
sleeping while in bed, experiencing disturbances throughout the night
and/or feeling tired during the day.
What's more, among students for whom stress is an
issue, frequent texting appears to make things worse, ultimately
undermining their overall sense of emotional well-being and contributing
to a higher risk for burnout.
"In other words, high levels of texting may exacerbate the negative psychological effects of stress," Murdock said.
At the same time, "sleep problems," she added, "may
occur because students continue to use their cellphones at night, which
pushes bedtime later and/or makes it difficult to fall asleep right
away. Also, students may be awakened in the middle of the night when an
incoming message makes their cellphone ring, buzz or light up."
Murdock reported her findings in a recent issue of the journal Psychology of Popular Media.
Considerable prior research (including a 2007 survey
by the American College Health Association) suggests that many college
students are significantly sleep-deprived, Murdock noted.
To explore texting's potential role in contributing
to sleep disturbance and stress, Murdock focused on the texting habits
of 83 first-year students (roughly two-thirds female) who were attending
what she describes as a "rigorous, southeastern liberal college."
Three-quarters were white, and all were between the ages of 18 and 21.
In addition to asking the students to report their
average daily texting routine, all underwent a battery of tests to
assess their stress levels; the degree to which they had experienced
academic and/or social burnout; and their emotional well-being as
reflected in how happy, satisfied and interested in life they had felt
over the prior month.
As well, all underwent standard assessments for sleep quality and signs of sleep disturbances.
The result: Higher daily texting lined up with
poorer sleep, perhaps because students felt compelled to respond to
incoming texts, no matter the time of day, Murdock said.
In addition, heavier texting activity was also
associated with increased difficulties in coping with stress for those
already experiencing it. And although the study did not specifically set
out to examine the reasons for this, Murdock suggested that the lack of
nuance, context and key visual cues that typifies texting could account
for the increased vulnerability to stress that the activity appears to
prompt.
"[And] text messaging is unique in the nearly perpetual
access to social contact that it provides," she explained. "[So] during
times of stress in social relationships, frequent texting may prevent a restorative or health-promoting pause in communication from occurring."
However, Murdock advised against concluding that texting raises the risk for severe mental health issues among college students.
"We measured academic and social burnout and
emotional well-being," she noted. "None of these is really a
psychological problem, like depression or anxiety. They are just
different aspects of well-being. [So] I would say the bottom line is
moderation in all things, including texting."
Tara Marshall, a lecturer in the department of
psychology at Brunel University's School of Social Sciences in Uxbridge,
England, also cautioned against reading too much into the study's
observations.
"Although these findings have potential implications
for students' well-being, namely that they should reduce their texting,
especially when feeling already stressed, it's important to note that
the findings are correlational and do not show that texting causes
reductions in well-being," she said.
"There could be other factors not measured in this
study that underlie both greater texting behavior and propensity for
interpersonal stress, " Marshall added, "such as higher neuroticism or
lower self-esteem. These personality traits could be responsible for the
link with burnout, sleep problems and compromised well-being, rather
than texting per se. Until these personality traits are taken into
account, and controlled experiments demonstrate that greater texting
causes sleep problems, the results of this study need to be taken with a
grain of salt. "
