في الرقم 6 جاءت الترجمة :
لوح أن يتنقل على مدار الساعة

ما معنى هذا الكلام ؟

حقيقة يبدو انها ترجمة حرفية، لكن لو دققنا بالنص الوارد في الموضوع، فمافهمته دكتور انه يتكلم عن اول ماظهر فيه التلفاز وماشابهه ، والمضار الناتجة عن استعماله،ومشكلة التعود عليه وتاثيره في شبكة العين، ومنكم نستفيد، ربما اتحفتنا بترجمة واضحة أكثر.

حسب الأطباء ترجمة كلمة Tablet هي حبة الدواء ، فهل يقصد وجود أدوية تؤثر على الساعة الدماغية . أردت الاستفسار فقط ؟

Evening use of light-emitting eReaders negatively affects sleep, circadian timing, and next-morning alertness


Significance


The use of light-emitting electronic devices for reading, communication, and entertainment has greatly increased recently. We found that the use of these devices before bedtime prolongs the time it takes to fall asleep, delays the circadian clock, suppresses levels of the sleep-promoting hormone melatonin, reduces the amount and delays the timing of REM sleep, and reduces alertness the following morning. Use of light-emitting devices immediately before bedtime also increases alertness at that time, which may lead users to delay bedtime at home. Overall, we found that the use of portable light-emitting devices immediately before bedtime has biological effects that may perpetuate sleep deficiency and disrupt circadian rhythms, both of which can have adverse impacts on performance, health, and safety.


Abstract
In the past 50 y, there has been a decline in average sleep duration and quality, with adverse consequences on general health. A representative survey of 1,508 American adults recently revealed that 90% of Americans used some type of electronics at least a few nights per week within 1 h before bedtime. Mounting evidence from countries around the world shows the negative impact of such technology use on sleep. This negative impact on sleep may be due to the short-wavelength–enriched light emitted by these electronic devices, given that artificial-light exposure has been shown experimentally to produce alerting effects, suppress melatonin, and phase-shift the biological clock. A few reports have shown that these devices suppress melatonin levels, but little is known about the effects on circadian phase or the following sleep episode, exposing a substantial gap in our knowledge of how this increasingly popular technology affects sleep. Here we compare the biological effects of reading an electronic book on a light-emitting device (LE-eBook) with reading a printed book in the hours before bedtime. Participants reading an LE-eBook took longer to fall asleep and had reduced evening sleepiness, reduced melatonin secretion, later timing of their circadian clock, and reduced next-morning alertness than when reading a printed book. These results demonstrate that evening exposure to an LE-eBook phase-delays the circadian clock, acutely suppresses melatonin, and has important implications for understanding the impact of such technologies on sleep, performance, health, and safety.

Real life trumps laboratory in matters of public health

The recent article by Chang et al. (1) adds to the growing literature that exposure to even seemingly dim light at night can have a negative impact on sleep. There have been several articles published in recent years indicating that the seemingly innocuous light emitted from consumer electronics devices has the capacity to increase alertness at night, thereby making it more difficult to initiate sleep (2). One of the problems that we have in judging the light emitted from these devices is that our conscious perception of light is mediated by a circuitry that both overlaps and yet is distinct from the circuitry underlying the mediation of light-induced alertness. This latter system, which also regulates the impact of light on other non–image-forming functions, such as circadian timing, is more sensitive to the shorter wavelength light that is abundant in most consumer electronic goods. Notably, the article by Chang et al. highlights the capacity of the non–image-forming system to respond to light. This article does not, however, answer the important public health question as to whether use of these devices at night is bad for your sleep.We and others, including Cheng et al., have demonstrated that the non–image-forming system compares light exposure patterns such that the impact of the light one receives at night is moderated by the amount of light one receives during the daytime (3, 4). In the current study, subjects were exposed to ∼90 lx for 12 h before a 4-h session in which they were exposed to the light from a light-emitting eReader. The 12 h of 90 lx (equivalent to spending the entire day in dim room lighting that is well below workplace standards for adequate lighting) would be quite abnormal for most people. Although institutionalized older individuals could be exposed to this lighting schedule, most individuals, even those of us bound to indoor jobs, are normally exposed to greater illuminance throughout the day, especially during the morning and lunch hour (in the tens of thousands of lux range). In fact, one of the authors of the current study reported that both older and young adults spend 37.7% and 27%, respectively, of their waking day in light exceeding 100 lx and 14.7% and 9% of their waking day in light exceeding 1,000 lx (5). Real-life light exposure desensitizes the non–image-forming system to the intensity of evening light exposure that was examined in this study. That is, the light emitted from the eReaders would have had a much smaller effect in alerting the brain than they would have had the participants been exposed to a normal pattern of everyday light exposure before using the eReaders before bedtime. Thus, the question still remains as to whether the light being emitted from an eReader, or any other type of electronic device, would actually impact nocturnal alertness and sleep in normally behaving individuals.
