Your Smartphone May Be Hurting Your SleepA) You love your smartphone, but it may be ruining your ZZZ’s. Use of these devices, especially near bedtime, is associated with worse quality of sleep, according to a new study. “When we looked at smartphone use around the time when participants reported they went to bed, more smartphone use around that time in particular was associated with a longer time to fall asleep and worse sleep quality during the night,” said Dr. Gregory Marcus, author of the study and an associate professor of medicine at the University of California, San Francisco. His research was published Wednesday in the journal PLOS One.B) The word “crack-berry” became popular roughly a decade ago to describe the addictive quality of BlackBerry devices—arguably the first really successful smartphones. Today, almost everyone is a smartphone junkie, standing with head bowed while waiting for a train or in line at the post office.C) Knowing that smartphone use has increased together with sleep deprivation rates, Marcus and his colleagues decided to investigate whether the two might be related. To answer this question, he used exiting information collected by an Internet-based study he started in March 2016.D) “Health E-Heart,” which was funded by the National Institutes of Health is designed to study cardiovascular health. Anyone 18 years of age or older can enroll in Health 11. Our addiction to smartphones dates back to about ten years ago._________ 12. Data from Health E-Heart are collected and used for researchers into heart diseases._________ 13. The findings of Dr. Marcus’s study appeared in PLOS One. _________14. Bad sleepers are advised not to use their smartphones half an hour or so before they go to bed. _________ 15. Marcus started his research because he suspected there might be some correlation between sleep loss and smartphone use. _________16. The use of digital devices affects children’s sleep too._________ 17. To make sure his study was objective, Marcus required his subjects to provide many more of their life details than just sleep hours and sleep quality._________ 18. Researchers found those who spend longer time playing with their smartphones are more likely to sleep badly._________19. Marcus conceded that some people were sleepless at night for reasons unrelated to mobile phone use._________ 20. Sleep is our basic biological need and lack of it may cause our body functions to decline. _________
