    Researchers unveil smart lighting that fights insomnia (2019/10/29)

    Sleeping well at night can get harder with age. A Taiwanese research team has developed a smart lighting system that they say can help seniors with sleep disorders. The indoor system is calibrated to simulate natural light. In the researchers' study, seniors with dementia were able to sleep 37% longer after just one month of use.

    This 85-year-old woman suffers from chronic insomnia. She's among the many elderly people who have what's called sundown syndrome. They sleep late and rise early, and their inner body clock is reversed. They are prone to experiencing mood swings and taking it out on their loved ones.

    My mood is poor and I don't sleep well. Nothing is wrong exactly, yet my mood is like this.

    When it comes to insomnia, there are good times and bad. At times when the patient has a fixed schedule of activities, sleep improves. The patient's mental state is very good.

    National Yang-ming University and an optoelectronics company worked together to develop smart lighting that mimics the color, wavelength and illumination of sunlight. The team exposed seniors with dementia to one hour of smart lighting per day. After one month, the seniors' average sleep time rose from five-and-a-half hours a night to seven hours and 13 minutes. That's an increase of 37%.

    If you're able to go outside and get good natural light, that's great. But if you're looking for results in a short amount of time, then you'll want to use the smart lighting. It can stimulate the production of serotonin, which at night becomes melatonin that helps you get a better night's sleep.

    Therapy with smart lighting can restore sleep cycles and bring normalcy back to the life of the elderly. The research team says it will first introduce the light system at hospitals, schools, and hotels. Researchers will also explore the light's effects on conditions like myopia, obesity, and depression. Their hypothesis is that better sleep leads to better health.

    長者睡眠品質差 "智慧光照"助增37%睡眠時間

    許多長者都有睡眠不足、失眠、夜間常常驚醒的困擾,甚至因此情緒暴躁或影響健康。陽明大學團隊研發"智慧光照",透過控制色溫、波長、特定角度,發現居然能幫長者拉長睡眠時間37%,改善睡眠卡卡。

    85歲的陳婆婆,長期飽受失眠之苦,像這樣有"黃昏症候群"的長者其實很多,晚睡早起,日夜顛倒,情緒變差,親友常成了受氣包。

    "失眠狀況就是時好時壞,有正常規律的活動,他就是睡眠有比較好,精神狀態也很好"

    陽明大學和光電業者產學合作,透過控制色溫、波長、照度,來模擬太陽光的變化,研發智慧光照。研究發現,失智高齡長者每天接受1小時智慧光照,在1個月後,每天平均睡眠時間,從5個半小時增至7小時13分,增加了37%。

    [[陽明大學護理學院院長 劉影梅]]
    "我們如果能到戶外接受很好的自然光,當然也很好。可是我們如果要在短時間有效果的話,就要運用我們的智慧光照。能夠讓他的血清素產生的更多,晚上變成我們的褪黑激素,就會睡得很好了"

    透過補充智慧光照,能讓長者維持規律生活和睡眠週期。研究團隊初步打算運用在醫院、學校、甚至旅館,並進一步研究對於近視、肥胖,憂鬱症的改善效果等,要讓"睡得好"治百病。
