Poor-quality Deep Sleep Is Due to Junk Food 常吃垃圾食品睡眠会变浅
A new study by Uppsala University in Sweden shows that junk food harms sleep. Healthy volunteers ate both unhealthy and healthy diets randomly. A poor diet leads to worse sleep quality than a healthy diet.
瑞典乌普萨拉大学的一项新研究表明,垃圾食品有害睡眠。健康的志愿者随机进行不健康和健康的饮食。与健康饮食相比,不良饮食会导致睡眠质量下降。
Some studies link diet to sleep changes, but few examine how diet directly affects sleep. One method is to give participants various diets to observe the effects randomly. Jonathan Cedernaes, Physician Professor at Uppsala University said, “Both poor diet and poor sleep increase the risk of several public health conditions. As what we eat is so important for our health, we thought it would be interesting to investigate whether some of the health effects of different diets could involve changes to our sleep.”
一些研究将饮食与睡眠变化联系起来,但研究饮食如何直接影响睡眠却很少。一种方法是给参与者不同的餐食以随机观察睡眠效果。乌普萨拉大学的内科教授乔纳森·塞德娜斯说:“不良饮食和睡眠不足都会增加患多种公共卫生疾病的风险。由于我们吃的东西对我们的健康如此重要,我们认为调查不同饮食对健康的一些影响是否会涉及我们睡眠的变化将是有趣的。”
Past studies show that sugary diets can lead to poorer sleep. Cedernaes notes that rest involves various physiological states such as deep sleep. However, no study compared deep sleep after unhealthy versus healthy diets in the same person. This is crucial because rest is dynamic, consisting of different stages with different functions and brain activity patterns. Understanding how diets affect these stages is essential, as factors like insomnia and aging can also impact sleep quality.
The study allowed 15 healthy young men to stay in a sleep lab for days. They ate healthy and unhealthy diets, with calories matching their needs. An unhealthy diet has more sugar, fat, and processed foods. They ate each diet for a week while their sleep and activities were monitored. Results showed junk food could have cut the deep sleep time.
过去的研究表明,含糖饮食会导致睡眠质量下降。塞德娜斯指出,休息涉及各种生理状态,如深度睡眠。然而,没有研究比较同一个人在不健康饮食和健康饮食后的深度睡眠。了解这一点至关重要,因为休息是动态的,由具有不同功能和大脑活动模式的不同阶段组成。了解饮食如何影响这些阶段至关重要,因为失眠和衰老等因素也会影响睡眠质量。
这项研究让15名健康的年轻男性在睡眠实验室待了一段时间。他们进行健康和不健康的饮食,并且热量符合他们的需求。不健康的饮食有更多的糖、脂肪和加工食品。这两种饮食他们各进行一周,同时监测他们的睡眠和活动。结果显示,在吃了垃圾食品后深度睡眠时间会缩短。
