辛苦工作了一天，睡前終于可以舒舒服服地躺在床上刷會手機，卸下一天的疲憊……這應(yīng)該是大部分人的生活寫照。但往往越刷手機人越興奮，入睡越困難。這是因為夜間光線尤其是手機屏幕的藍光，會抑制褪黑素的分泌，從而造成入睡困難，同時也使大腦保持興奮而降低睡眠質(zhì)量。

如果你一時無法徹底改掉這個習(xí)慣，但又想提高睡眠質(zhì)量，可以設(shè)置鬧鐘提醒自己控制睡前玩手機的時長。此外，還應(yīng)該適當補充褪黑素。有研究表明，堅果、魚類、雞蛋、櫻桃和牛奶富含褪黑素。日常多攝入這幾類食物或有助于提高睡眠質(zhì)量。

Melatonin supplements are a great way to get some sleep, but some of the foods in your fridge and pantry may already have the melatonin you need.
服用褪黑素是一種助眠的好方法，但日常生活中的一些食物已經(jīng)含有人體所需的褪黑素。

Melatonin is defined by the CDC as a neurohormone that regulates the sleep-wake cycle. And it can be really helpful for stabilizing your sleep pattern. Light, especially the blue light from phone screens, can affect melatonin levels, says Yo-El Ju, a neurologist and sleep medicine specialist at Washington University in St. Louis.
美國疾病控制與預(yù)防中心將褪黑素定義為調(diào)節(jié)人體生物鐘的神經(jīng)激素，有穩(wěn)定作息的作用。圣路易斯華盛頓大學(xué)神經(jīng)學(xué)家和睡眠醫(yī)學(xué)專家尤爾·朱表示，光線，特別是手機屏幕上的藍光，會影響褪黑素水平。

To combat melatonin deficiency in recent years, more people began using melatonin supplements as a sleep aid. According to a research letter published by JAMA in February of this year, prevalence of melatonin use rose to 2.1% in 2017 to 2018 from 0.4% in 1999 to 2000.
近年來，為了對抗褪黑素缺乏癥，越來越多人開始口服褪黑素助眠。美國醫(yī)學(xué)會今年2月公布的一項研究顯示，褪黑素服用者的比例從1999年至2000年的0.4%上升至2017年至2018年的2.1%。

But in addition to the melatonin that is already produced in the brain, you can get natural doses of the hormone from your next snack. “Melatonin is actually present in food,” according to Ju.
但除了大腦產(chǎn)生的褪黑素外，你還可以從食物中補充自然的褪黑素。尤爾·朱稱：“實際上，食物中含有褪黑素?！?/p>
