@Charlotte Gartenberg : 我今天采访了华尔街日报科学部门主管@Joe Craven-McGinty ,讨论了新型可穿戴睡眠设备。这些设备利用声音和光线来改善睡眠,通过干扰脑电波模式,帮助人们更快入睡,睡得更香,睡得更久。我了解了Ellamind、Somni和Lumos三家公司开发的设备,它们分别使用声音脉冲、电脉冲和光线来调节脑电波。这些设备的价格在250美元到400美元之间,有些还提供可选的订阅服务。此外,我还了解到一些免费的改善睡眠方法,例如在黑暗安静的房间睡觉,以及处理好一天中的压力事件。 Joe Craven-McGinty: 脑电波在不同睡眠阶段的频率不同。清醒时脑电波频率为8-12赫兹,深睡时为0.5-2赫兹。Ellamind公司研发的头带式设备通过声音脉冲来调节脑电波,在30分钟内发出约15000个声音脉冲,这些脉冲的时机非常精确,以改变脑电波震荡模式。虽然声音脉冲听起来像洒水器的声音,但为了舒适性,设备还会播放舒缓的雨声。Somni设备则使用电脉冲而非声音脉冲来调节脑电波,用户可能会感到轻微的刺痛和温暖感。Lumos睡眠眼罩则通过光线来调节人体生物钟,帮助人们适应时差或调整睡眠作息。这些设备的有效性已在同行评审期刊上发表,例如Somni设备平均能让使用者多睡22分钟,Ellamind设备平均能让使用者提前10分钟入睡。 Joe Craven-McGinty: 除了这些科技产品,我还采访了荷兰睡眠研究员Martin Dressler,他指出一些免费的改善睡眠方法,例如在黑暗安静的房间睡觉,以及处理好一天中的压力事件。这些方法同样有效,并且不需要任何成本。
