An American organisation that promotes healthy amounts of sleep each night is claiming that the use of gadgets an hour before sleep is affecting how people sleep and that a significant number of Americans aren't getting the sleep they say they need and are searching for ways to cope.
"This poll explores the association between Americans' use of communication technologies and sleep habits," says David Cloud, CEO of the National Sleep Foundation. "While these technologies are commonplace, it is clear that we have a lot more to learn about the appropriate use and design of this technology to complement good sleep habits."
Americans report very active technology use in the hour before trying to sleep. Almost everyone surveyed, 95%, uses some type of electronics like a television, computer, video game or cell phone at least a few nights a week within the hour before bed. However, baby boomers (46-64 year olds), generation X'ers (30-45 year olds), generation Y'ers (19-29 year olds) and generation Z'ers (13-18 year olds) report very different technology preferences.
About two-thirds of baby boomers (67%) and generation X'ers (63%) and half of generation Z'ers (50%) and generation Y'ers (49%) watch television every night or almost every night within the hour before going to sleep.
"Artificial light exposure between dusk and the time we go to bed at night suppresses release of the sleep-promoting hormone melatonin, enhances alertness and shifts circadian rhythms to a later hour - making it more difficult to fall asleep," says Charles Czeisler, PhD, MD, Harvard Medical School and Brigham and Women's Hospital. "This study reveals that light-emitting screens are in heavy use within the pivotal hour before sleep. Invasion of such alerting technologies into the bedroom may contribute to the high proportion of respondents who reported that they routinely get less sleep than they need."
Computer or laptop use is also common. Roughly six in ten (61%) say they use their laptops or computers at least a few nights a week within the hour before bed. More than half of generation Z'ers (55%) and slightly less of generation Y'ers (47%) say they surf the Internet every night or almost every night within the hour before sleep.
"My research compares how technologies that are 'passively received' such as TVs and music versus those with 'interactive' properties like video games, cell phones and the Internet may affect the brain differently," says Michael Gradisar, PhD, Flinders University (Australia). "The hypothesis is that the latter devices are more alerting and disrupt the sleep-onset process. If you feel that these activities are alerting or causing you anxiety, try doing something more 'passive' to help you wind down before bed."
Cell phone use, specifically texting and talking on the phone, shows a significant age gap. More than half of generation Z'ers (56%) and nearly half of generation Y'ers (42%) say they send, read or receive text messages every night or almost every night in the hour before bed compared to 15% of generation X'ers and 5% of baby boomers.
Cell phones were sometimes a sleep disturbance. About in one in ten of generation Z'ers (9%) say that they are awakened after they go to bed every night or almost every night by a phone call, text message or email. About one in five of generation Y'ers (20%) and generation Z'ers (18%) say this happens at least a few nights a week.
"Unfortunately cell phones and computers, which make our lives more productive and enjoyable, may also be abused to the point that they contribute to getting less sleep at night leaving millions of Americans functioning poorly the next day," says Russell Rosenberg, PhD, Vice Chairman of the National Sleep Foundation.
For those who are employed and report not getting adequate sleep, about three quarters (74%) of those over 30 said that sleepiness affects their work.
