cell phone and sleep quality

the objective of this study was to find out the association between mobile use and physiological parameters of poor sleep quality. we also aimed to find out the prevalence of mobile-related sleep risk factors (mrsrf) in mobile users and their effects on sleep, ie, using mobile before sleeping after the lights have been turned off, not enabling airplane mode on mobiles, putting the mobiles near or below the pillows and bedside while sleeping. the online questionnaire was shared with each class on their whatsapp groups, and a time of 8 minutes was provided to the students to fill the questionnaire.




comparison of sleep quality in the participants with various mrsrf is shown in table 3. data indicated that the subjects who use the mobile after the lights have been turned off for at least 30 minutes (without a blue light filter in mobile), and who put the mobile near their pillow while sleeping have a statistically significant poor sleep quality (p=0.001, 0.001) respectively. this difference may be due to the reason that their study population included younger subjects from grades 7 to 12 only, who are under strict supervision of their parents as compared to the older adults.29 one supreme finding of this study was that using mobile for at least 30 minutes after the lights have been turned off (without a blue light filter in mobile) correlates with poor sleep quality, daytime sleepiness, sleep disturbances and increased sleep latency. as 88.7% of the subjects mentioned that they used mobile for at least 30 minutes after the lights are turned off, blue light filter feature was used by only 4.2% of the participants. so we recommend further experimental and case control studies to probe the role of these causal factors, especially (rf-emf and blue light emitted from mobile screens), in causing poor sleep quality.

this study’s main objectives are to examine the prevalence of smartphone usage at bedtime and its effect on sleep quality among saudi non-medical staff working in king saud university medical city in riyadh, saudi arabia. have reported that a mobile phone use of more than 2 hours is related to poor sleep and decreased sleep time in medical students in india. [14] few researchers have explored the associations between bedtime usage of smartphone and sleep quality in adults both in saudi arabia and internationally. [20] we performed a study designed to test the hypothesis that there is an association between smartphones usage at bedtime and sleep quality. the first section is an introduction about the study purpose and reassurance of confidentiality.

the arabic version of pittsburgh sleep quality index (psqi) was used, and permission was taken from the author to use it. for analytical statistics, odds ratio and its 95% confident interval were used to test the risk of poor sleep quality among participants who used smartphones at bedtime. table 4 indicates that the risk of poor sleep quality is around two-fold among those who use a smartphone at bedtime for 16 to 30 minutes. [15] however, the mechanism of the effect of smartphone usage at bedtime on sleep quality is not clear. although we have found a clear association between smartphone usage at bedtime and poor sleep quality, we do not know whether poor sleep quality leads to the use of a smartphone or vice versa. thus, further studies are needed with larger sample size, broader population, and a study design that would reveal the causality.

purpose. the objective of this study was to find out the association between mobile use and physiological parameters of poor sleep quality. [6] yogesh et al. have reported that a mobile phone use of more than 2 hours is related to poor sleep and decreased sleep time in medical students in india. electronic back-lit devices like cell phones, tablets, readers, and computers emit short-wavelength enriched light, also known as blue light., cell phone radiation disrupts sleep, cell phone radiation disrupts sleep, cell phones and insomnia, cell phones and sleep deprivation statistics, using phone at night bad for eyes.

the blue light emitted by your cell phone screen restrains the production of melatonin, the hormone that controls your sleep-wake cycle (aka circadian rhythm). this makes it even more difficult to fall asleep and wake up the next day. studies have shown that the blue light emitted by your smartphone is bad for your vision. but it can be bad for your sleep, too. exposure to blue light can affect your internal body clock and throw off your circadian rhythm. in fact, media use before bedtime or after lights out, including mobile phone use, has been associated with sleep loss, poorer sleep quality, and increased however, our brains are very sensitive to light, and the blue light (5) emitted from cell phones and other electronic devices delays avoid your smartphone, tablet or laptop beginning two to three hours before bed. if you use your phone as an alarm clock, set it once and keep it out of reach, sleeping with electronics near head, how long before bed should you turn off electronics, benefits of turning your phone off at night, how does phone use before bedtime affect sleep what is the independent variable, how to stop using phone before bed, does screen time affect sleep in adults, national sleep foundation, screen time doesn t affect sleep, technology and sleep statistics, blue light and sleep.
