For Lisa Hanson, a stay-at-home mother in San Francisco, the alarm that used to rouse her out of sleep most mornings was the sound of her toddler. 对于丽萨.汉森这位生活中旧金山的全职妈妈来说，经常在早上把她从睡梦中叫醒的就是她一岁的儿子的发出的声音了。
“He wakes up at 5:30 screaming sometimes,” she said. “It would jolt me awake, and then I’d be miserable and groggy all morning because I’d be woken up when I’m in my deepest sleep.”
“他早上5：30就醒了，有时候还哇哇大叫，”她说，“他的尖叫把我震醒，然后整个早上我都感到痛苦眩晕，因为我都是在熟睡的时候被叫醒。”
But last month, Ms. Hanson started using a new program, the Renew Sleep Clock, an iPhone app that keeps track of her sleep. Its makers, GEAR4, say that the app uses radio sensors to detect breathing patterns and movements at night, then uses that information to wake a person at the lightest point of sleep, the optimal time to wake up. The theory is that awaking from light sleep, as opposed to the deep stages of sleep, helps reduce so-called sleep inertia, the cloud of grogginess and impaired alertness that makes people desperately want to crawl back into bed. The app also acts as a sort of sleep adviser, giving Ms. Hanson guidance about the amount of shut-eye to shoot for and ways to get there.
但是上个月，汉森女士开始使用一种新型软件，“睡眠更新钟”，一款iPhone 应用可以追踪用户的睡眠。这款应用的研发团队GEAR4说“睡眠更新钟”使用无线遥感器以监测使用者夜晚的呼吸模式和行动，接下来利用收集的信息在使用者睡得最轻的时候把使用者叫醒，也就是最理想的起床时间。这个理论，即在最轻度睡眠时把使用者叫醒，与深度睡眠相反，有助于降低所谓的睡后迟钝、由睡眠不足引起的身体衰弱和警惕度受损，而就是这些状况让人们迫不及待地想要爬回床上。此外，“睡眠更新钟”还起到了睡眠咨询师的作用，告知汉森女士需要多少眼睛开合的次数以及如何达到这一数字。
“Since I’ve been using it, I do feel better,” Ms. Hanson said. “It’s waking me up in a more ideal stage of sleep and helping me have that much better of a day.”
“自从开始使用这项应用，我确实感觉好多了，”汉森女士说，“它让我在更为理想的状态下醒来，让我在接下来的一天来过得更好。”
