#研究分享#【白天光照能减少屏幕蓝光对夜间睡眠的影响】夜间使用手机和平板已被证实会干扰睡眠,而一项来自神经科学的最新研究表明,白天接受充足的光照,例如通过户外活动,或者在办公室导入光照,可以降低电子设备的蓝光刺激对夜间睡眠的影响。不过,即使没有蓝光的影响,睡前查看e-mail或社交网络也会唤起情绪,导致睡眠障碍,因此睡前最好不要接触。http://www.looooker.com/archives/32609

Does-blue-light-really-affect-your-sleep

The use of smartphones and tablet computers during evening hours has previously been associated with sleep disturbances in humans. A new study from Uppsala University now shows that daytime light exposure may be a promising means to combat sleep disturbances associated with evening use of electronic devices. The findings are published in the scientific journal Sleep Medicine.

 

The use of blue light emitting devices during evening hours has been shown to interfere with sleep in humans. In a new study from Uppsala University involving 14 young females and males, neuroscientists Christian Benedict and Frida Rångtell sought to investigate the effects of evening reading on a tablet computer on sleep following daytime bright light exposure.

 

'Our main finding was that following daytime bright light exposure, evening use of a self-luminous tablet for two hours did not affect sleep in young healthy students', says Frida Rångtell, first author and PhD student at the Department of Neuroscience at Uppsala University.

 

'Our results could suggest that light exposure during the day, e.g. by means of outdoor activities or light interventions in offices, may help combat sleep disturbances associated with evening blue light stimulation. Even if not examined in our study, it must however be kept in mind that utilizing electronic devices for the sake of checking your work e-mails or social network accounts before snoozing may lead to sleep disturbances as a result of emotional arousal', says senior author Christian Benedict, associate professor at the Department of Neuroscience.
