Insomnia is another short term effect from using cellphones. Teens and young adults are more likely to stay up and search the web before falling asleep than adults, but don’t think adults are innocent. According to a 2012 Time/Qualcomm poll, nearly three fourths of people around the world, from age 18 to 44 sleep with their phones within reach.
In a study examined by researchers from Baylor University in Texas, which is published online in the Journal of Behavioral Addictions, more than 200 college students publicized that each student lost an average of about 45 minutes of sleep each week due to being on their cell phones. Sue K. Adams, the assistant professor of human development and family studies says, "Students who feel compelled to wake up in the middle of the night and answer texts and answer phone calls is strange to me.” She told The Chronicle of Higher Education, “you would imagine there’s something about them that’s driving them to feel like they have to stay connected."
Fox News states that scientists that studied 35 men and 35 women found that using the phones before going to sleep slows down and shortens the deep sleep stages, which is the portion of sleep that allows the brain to shut down and the body to repair from the day. A lot of times cellphone users use their cellphones as alarm clocks to wake them up in the morning, making it almost impossible not to reach for the phone when it is that easily accessible.
