BALTIMORE (UPI) -- Teens who use their cell phone excessively are more
prone to disrupted sleep, restlessness, stress and fatigue, Swedish
researchers said.
Dr. Gaby Badre of Sahlgren's Academy in Gothenburg, Sweden, studied 21
healthy subjects ages 14 to 20, with regular working/studying hours
and without sleep problems.
The subjects were broken up into two groups: a control group of three
men and seven women and the experimental group of three men and eight
women. The control group made less than five cell phone calls and/or
sent five text messages a day, while the experimental group made more
than 15 calls and/or sent 15 text messages a day. The subjects were
then asked questions regarding their lifestyle and sleep habits.
The study found that those who did more cell phone calling and text
messaging have increased restlessness with more careless lifestyles,
more consumption of stimulating beverages, difficulty in falling
asleep and disrupted sleep and more susceptibility to stress and
fatigue. They behave more like larks than owls, suggesting a delayed
biological clock, Badre said.
The findings were presented at the 22nd annual meeting of the
Associated Professional Sleep Societies in Baltimore.
