To many parents, text messaging is an enigma -- a practice their children engage in when they could just make a phone call or walk down the street to their friends' houses. It seems to be a strange but harmless means of communication.
What most don't know is that too much texting can actually be detrimental to their teens' health. That's because new technologies, such as cell phones and social-networking sites, give teen-agers easy access to their friends 24 hours a day.
"The more technology we develop, the more we rely on technology," said Dr. Myrza Perez, a pediatric pulmonologist at Capital Allergy and Respiratory Disease Centers in Roseville and Folsom, Calif. A specialist in sleep disorders, she says that "before technology, we went to sleep when the sun went down. Now, with all these distractions, teen-agers alone in their rooms stay up to extremely late hours on their cell phones and computers. Their parents have no idea."
The trend of sleep deprivation is leading to many daytime problems for teen-agers, including headaches, impaired concentration, weakened immune systems, crankiness, increased use of nicotine or caffeine and hyperactive behavior often misconstrued as attention deficit hyperactivity disorder.
These symptoms are often interpreted by doctors as problems meriting medication, when in fact the best cure might be to turn off their cell phones at night.
Mikaela Espinoza, 17, always used to sleep with her phone at her bedside, just in case a friend called or text-messaged her in the middle of the night. Sometimes, she said, she would receive calls or messages as late as 3 a.m. -- and she would wake right up to call or text right back.
"Whenever I'd hear my phone ring I would just, like, wake up and answer it," Espinoza said. "I think a whole bunch of kids text like all night long."
Espinoza soon found herself suffering from near-debilitating migraine headaches throughout the day. She couldn't concentrate in school, she couldn't go out with her friends, she couldn't be herself, she said. Her primary physician's first instinct was to check her eyes. When that yielded no solutions, he sent her in for a CAT scan. It came back clear. "Nobody knew what was wrong with me," Espinoza said.
Eventually, Espinoza was diagnosed with a condition growing more and more common among teen-agers: too much texting.
"After they realized I wasn't getting enough sleep, they told me I needed to turn off my phone or have it taken away from me at night," she said. "My mom was real mad at me."
According to the National Sleep Foundation, school-age children and adolescents need at least nine hours of sleep a night. But in a national survey conducted in 2006, only 20 percent of American teens said they get nine hours a night. Nearly half sleep less than eight hours on school nights, and 28 percent of high-school students reported falling asleep in school at least once a week.
The problem, experts estimate, has only worsened since then.
Cell phones are not the only culprits of sleep deprivation, Perez said. Video games and computers contribute to teen-agers' inclination to stay up all night.
"Cell phones, computer screens and even televisions emit light rays that keep you awake," Perez said. "Light automatically stimulates the retinas. Before bed, people should turn off those devices and switch to a quieter, healthier activity, like reading."
Dr. Amer Khan, a pediatric neurologist who practices at Sutter Roseville Medical Center and Sutter Medical Center in Sacramento, Calif., said part of the problem lies in an all-around ignorance of sleep disorders, one of his specialties.
"Sleep problems are often masked and hidden behind daytime problems," Khan said. "The patients don't realize it's a sleep problem, and their physicians don't realize it's a sleep problem, so they get treated and diagnosed as daytime problems when that's not the case."
Marvin Green, 19, suffers from sleep apnea, a condition characterized by pauses in breathing during sleep. He was not diagnosed until he was 17 years old.
Sleep problems, like sleep apnea, are often misdiagnosed in young patients because the symptoms that manifest during the day can be misleading.
"Kids manifest a lack of sleep with hyperactivity," Perez said. "A lot of people in the sleep field would know that should at least prompt a sleep assessment. But most people don't go to a pediatrician saying they're having trouble sleeping, and there's always so much ground to cover in one general health checkup that sleep problems just get overlooked."
Green said he was put on medication for other conditions and never thought much about the quality of sleep he was receiving.
"I would get these terrible migraines and would fall asleep in school sometimes," Green said. "I thought it was stress. I started not sleeping as much because of the headaches, and then the headaches would get worse because of the lack of sleep. It was a Catch-22."
Part of the problem, experts say, is that individuals are not sleep-conscious and are never taught how to maintain healthy sleep habits like going to sleep and waking up at a consistent time every day, not eating or exercising right before bed and turning off noise -- and light-emitting devices including televisions, computers and cell phones.
Green said he was unaware of just how important sleep is, noting it was never taught or discussed in health classes and was not discussed by his primary care physician.
Now he, like Espinoza and countless other teen-agers who have experienced the debilitating effects of a lack of sleep, understands that a little shut-eye can go a long way.
"You can't really function in the daytime without it," Green said.
