美國國家睡眠基金會(huì)今天發(fā)布了每年一次的睡眠調(diào)查結(jié)果，1500多名調(diào)查樣本的年齡介乎于13到64歲之間。 調(diào)查的某些結(jié)果顯示：43%的美國人表示他們每星期很難得有一晚能睡得好。 幾乎所有人——樣本中的95%——在睡前一小時(shí)內(nèi)接觸過電子儀器（例如電視機(jī)、電腦或電話）。研究人員提醒道，使用這些設(shè)備不利于進(jìn)入睡眠狀態(tài)，因?yàn)檫@些人造光源會(huì)抑制褪黑激素的釋放，而褪黑激素是我們的睡眠激素。 超過50%的青少年每晚睡覺之前會(huì)收發(fā)短信，而在那些三十多歲以及在嬰兒潮時(shí)期出生的人群當(dāng)中，會(huì)這樣做的人比例分別只有15%和5%。 青少年是最犯困的群體，而嬰兒潮時(shí)期出生的人睡得最多?？茖W(xué)家提醒道，因?yàn)榇蠖嗲嗌倌甑乃邥r(shí)間比我們推薦的9小時(shí)要少2小時(shí)，所以也許少發(fā)一些OMG（天哪！）和ROFL（笑得打滾）會(huì)讓你在睡前平靜下來。
