為什么你會(huì)睡不好？

Are you tired of waking up more tired than when you went to bed？ Does it seem like a good nights sleep is more elusive than your half-remembered dreams？ If youve been having a tough time falling asleep lately， chances are， the cause is either something youre doing， or something youre not doing. Here are some common reasons youre having a hard time sleeping well.

你是否覺得醒來的時(shí)候比上床睡覺的時(shí)候更累？是否覺得一個(gè)好覺比一個(gè)依稀記得的夢更加難得？如果你最近一直很難入睡，有可能原因在于你正在做的某些事情或者你沒做的某些事情。以下是一些常見的導(dǎo)致睡眠質(zhì)量差的原因。

Nighttime Exercise

A casual around-the-block stroll1 with your dog before his bedtime is fine， but a heart-pumping， sweat-dripping cardio workout2 within three hours of your own bedtime is too much. Your body temperature and heart rate naturally drop as you fall asleep—but exercise raises those two body functions， and stimulates your entire nervous system， making it tough to sleep. Instead， schedule your workout for the morning， or hit the gym on your lunch hour.

夜間鍛煉

在你的狗睡覺前牽著它在街區(qū)里悠閑地散步?jīng)]什么問題，但是在你自己就寢前三小時(shí)以內(nèi)做讓人心跳加劇、汗流浹背的有氧運(yùn)動(dòng)就過頭了。當(dāng)你入睡的時(shí)候你的體溫和心率會(huì)自然下降，然而鍛煉會(huì)讓它們升高，刺激你的整個(gè)神經(jīng)系統(tǒng)，讓你很難入睡。因此，將你的鍛煉安排在早上，或者在午餐時(shí)間去健身房會(huì)更好。

Room Temperature

Most sleep experts recommend keeping your bedroom at a moderate3 18 to 22 degrees at night， but many people like to cut energy costs by turning the thermostat4 down to the freeze zone during the winter， and switching the AC5 off during the summer， leading to a sweltering bedroom. However， your body needs to cool slightly at night for the most refreshing sleep， which is impossible in an overly heated bedroom. A too-cold room， on the other hand， will wake you up. If you dont want to adjust the thermostat to the comfort zone， then wear thick socks to a well-blanketed bed during cold days， and set up a portable fan next to your bed in the summer.

房間溫度

大多數(shù)睡眠問題的專家建議晚上保持臥室溫度在舒適的18至22度之間，但很多人為了削減能源開銷喜歡在冬季把恒溫器調(diào)低到冷凍區(qū)間，在夏季關(guān)掉交流電源，使得臥室悶熱。然而，你的身體需要一個(gè)稍微涼爽點(diǎn)的環(huán)境來進(jìn)行讓人恢復(fù)精神的睡眠——在一個(gè)熱烘烘的臥室里這是不可能的。另一方面，一個(gè)太冷的房間又會(huì)讓你清醒。如果你不想把恒溫器調(diào)到舒適區(qū)，那么在寒冷的日子里就穿厚襪子，把床蓋得暖暖的，夏天則在床邊放一個(gè)便攜式的風(fēng)扇。

Stress and Worry

Probably the most common non-medical reason for short-term insomnia6 is a mind filled with worries or stress. During the day， the activities of life tend to distract you， but once you settle yourself into bed， your mind is free to roam. For most people， its not the good aspects of their lives that their mind chooses to focus on， but rather， the negatives. You can improve this in several ways.

1. Write down your worries before bedtime， along with a few things you are grateful for， as a regular part of your nighttime routine.

2. If your mind really starts to fret7， get out of bed—without turning on any lights—and go sit in another dark part of the house. This breaks the worry cycle and youll probably find your mind quickly calms down enough to return to bed.

3. One of the most effective ways to conquer worry and stress is with a daily meditation practice. You dont need to be an expert yogi or spend hours sitting on a mat—as little as ten minutes each day is beneficial.

壓力和焦慮

也許最常見的短期失眠的非醫(yī)學(xué)原因是焦慮或壓力。白天，生活中的各種活動(dòng)往往會(huì)分散你的注意力，但一旦你躺到了床上，你的意識(shí)就開始自由地漫游。對(duì)大多數(shù)人來說，注意力不會(huì)集中到他們生活中好的方面，而是恰恰相反，集中在了消極的方面。你可以用以下幾種方法去緩解。

1. 在睡覺前寫下你的擔(dān)憂和一些令你感到愉快的事情作為你每晚的習(xí)慣。

2. 如果你真的開始煩躁，離開床，不打開任何燈，坐在屋子里的另一個(gè)黑暗的地方。這可以打破焦慮圈，你可能會(huì)發(fā)現(xiàn)你的心很快就平靜下來了，你也可以回到床上了。

3. 戰(zhàn)勝壓力和焦慮的最有效的方法之一是每天冥想練習(xí)。你不需要成為一個(gè)瑜伽專家或花幾個(gè)小時(shí)坐在墊子上，每天花短短的十分鐘都是有好處的。

Late Afternoon Caffeine

You know a bedtime cup of coffee is a bad idea， but did you know that the half-life of caffeine is 3 to 5 hours， leaving the remaining half in your body for many hours more？ Thats why a late afternoon cup of Joe8 can disrupt your sleep later that night. Although caffeines effects on you depend on your tolerance， the dose and your age， it is best to keep your consumption below 400 mg per day， and stay away from caffeine sources after lunchtime.

午后的咖啡

你知道睡前喝杯咖啡是一個(gè)壞主意。但你知道咖啡因的效果減半的時(shí)間為3到5個(gè)小時(shí)，留在你的身體里的剩下的一半的效果的時(shí)間會(huì)更長嗎？這就是下午晚些時(shí)候的一杯咖啡可以擾亂你的睡眠的原因。雖然咖啡因?qū)δ愕挠绊懭Q于你的耐受性、劑量和你的年齡，但是最好讓你的攝入量在每天400毫克以下，并且在午餐后遠(yuǎn)離各種咖啡因來源。

Too Much Light

Whether its coming from your reading lamp， the television， or outside your window， light exposure at bedtime impairs your quality of sleep. For some people， even the light of a bedside alarm clock is enough to signal their brain that its time to wake up. Luckily， this is one sleep issue thats easy to solve. Turn off your electronics （including phones， tablets and laptops） at least an hour before bedtime. If light from an outside source shines into your bedroom， hang curtains （this is especially important if you work nights and need to sleep during the day）. Close your bedroom door to shut out light from other areas of the house. Or for the simplest solution， put on a sleep mask before closing your eyes.

光線太亮

無論光是來自你的閱讀燈，電視，還是來自你的窗戶外面的光源，在睡覺時(shí)亮光都會(huì)損害你的睡眠質(zhì)量。對(duì)一些人來說，即使是床邊鬧鐘的光也足以使他們的大腦發(fā)出該清醒的信號(hào)。幸運(yùn)的是，這是一個(gè)很容易解決的問題。至少在睡前一個(gè)小時(shí)關(guān)掉你的電子產(chǎn)品（包括手機(jī)，平板電腦和筆記本電腦）。如果有外部光源的光照進(jìn)你的臥室，掛起窗簾（如果你是夜晚工作，白天睡覺的話，這是尤其重要的）。關(guān)上你的臥室門以阻隔從房子的其他區(qū)域射過來的光?；蛘哂米詈唵蔚霓k法，在睡前帶上眼罩。

The Wrong Snack

Is your bedtime snack a slice （or two） of pizza or a bag of chips？ If so， dont be surprised when youre lying awake staring at your ceiling. A full load of fat or protein right before bedtime sends your digestive system into overdrive， making it difficult to sleep. But hunger pains can wake you up as well. Proper diet of dinner is the best choice.

錯(cuò)誤的零食

你的睡前零食是一片（或兩片）披薩餅或者一袋薯?xiàng)l嗎？如果是這樣的話，當(dāng)你躺在床上（睡不著）盯著天花板時(shí)，不要感到驚訝。臨睡前滿滿的脂肪或蛋白質(zhì)會(huì)讓你的消化系統(tǒng)超速運(yùn)轉(zhuǎn)，讓你難以入睡。但饑餓的痛苦也同樣會(huì)喚醒你。晚餐時(shí)合適的飲食是最佳的選擇。
