Penchant for watching TV every night before bed, playing video games until midnight, or check electronic mail or short messages (SMS) before turning off the lights can disrupt sleep.
"Unfortunately, cell phones and computers that make our lives more productive and fun it can be annoying to the point that makes us less sleep and make millions of Americans do not fresh the next day," said Vice Chairman of the National Sleep Foundation (NSF) based in Washington, Russell Rosenberg in a statement.
Nearly 95 percent of people who questioned the NSF say they use some electronic equipment an hour before bed and two-thirds admit they do not get enough sleep in one week.
Charles Cziesler from Harvard Medical School and Brigham and Women's Hospital in Boston said the exposure from artificial light before bedtime can improve alertness and withhold the release of the hormone melatonin to promote sleep.
"Technology has invaded the bedroom," Czeisler said in an interview. "Invasion by the technology that makes people wake up it can have an impact on the high number of respondents who said they experienced less sleep on a regular basis from the amount of sleep they need."
Baby boomers or people aged 46-67 years was the largest age group who watched television every night before bed, while more than a third group of 13-18 years and 8 percent of youth aged 19-29 years old played video games before bed.
Sixty-one percent also said they use a computer or portable computer at least a few nights each week.
The tendency to keep in touch with technology, meaning there are more people who have overcome the problem because the sound mobile phone, SMS or letter elektoronik at night.
"One in ten children said they were awakened by an SMS after sleeping, people do not turn off their Blacberry," Czeisler said, adding that this becomes a burden to sleep activity.
Generation Z, aged 13-18 years, are the most sleep deprived with 22 percent. They are "sleepy" compared to nine percent of baby boomers.
Sleep experts recommend teens to sleep 9 hours 15 minutes at night, but the teenagers who were interviewed claimed to only sleep on average for 7 hours and 26 minutes.
"I am most worried about lack of sleep the age group 13-18 years," said Czeisler. "Kids today from 1.5 to 2 hours less sleep each night than those in the same age a century ago. That means they lose 50 hours of sleep per month," he said.
Lack of sleep for the American people have a negative impact on employment, mood, family, driving habits, sexual and health conditions, according to NSF.
All age groups consume caffeinated beverages - about 354 milliliters per person - per day and do take a nap, sometimes more than once in one day.
"Parents need to get rid of this kind of technology, children's bedrooms if they wish their children well (in school)," said Czeisler.
