Here’s the 6 steps I take to fall asleep quickly and get a good night’s sleep.
以下是我快速入睡而且睡得好的6個步驟。

1. Make Your Bedroom Pitch Black
1.臥室漆黑

Our brain associate darkness with night, and light with day. Being in a bright room filled with screens decreases melatonin production and makes your body believe it’s daytime.
我們的大腦會把黑暗和夜晚、光和白天聯(lián)系在一起。在滿是屏幕的明亮房間里體內(nèi)褪黑素會減少，身體認(rèn)為仍然是白天。

2. Make Your Bedroom Quiet
2.臥室保持安靜

Sounds can also decrease your sleep quality and wake you up. Get earplugs if you don’t have control over your environment.
聲音也會降低睡眠質(zhì)量并把你弄醒。如果無法控制周圍環(huán)境就戴上耳塞。

3. Sleep in the Perfect Temperature
3.室內(nèi)溫度適宜睡眠

The ideal sleep temperature is about 65-70°F (18-21 °C).
理想的睡眠溫度約是65-70°F (18-21 °C)。

4. Block Blue Light
4.躲開藍(lán)光

The blue light from devices like phones, TVs and computers decrease melatonin production. The best thing would be to not use devices 3 hours before bedtime, but we all know that’s not going to happen. Fortunately, tech can help us by removing most blue light from the screen. Here’s the free programs for all devices and platforms:
來自電話、電視和電腦等電子產(chǎn)品的藍(lán)光會減少體內(nèi)的褪黑素，最好睡前3小時內(nèi)不用這些設(shè)備，但我們都知道這不可能。幸運的是，科技能幫我們從屏幕上移除大部分藍(lán)光。下面就是所有電子產(chǎn)品和平臺都能用的免費程序：

Windows, OS and Linux people: download .
Windows, OS and Linux用戶下載。

Android people: download the app Twilight.
安卓用戶下載應(yīng)用程序Twilight。

To maximize the benefits, buy a pair of blue blocking glasses. They're good for blocking blue light coming from lamps and devices where these apps aren't available. You'll look dorky, but they can increase sleep quality by 50%.
為了在最大程度上保證睡眠質(zhì)量，可以買一副防藍(lán)光眼鏡，它可以很好地阻擋來自燈和不能用這些應(yīng)用程序的電子產(chǎn)品的藍(lán)光。雖然看起來不怎么時髦，但可以使睡眠質(zhì)量提高50%。

5. Be Smart About What You Eat and Drink
5.注意飲食

What you consume can affect your sleep significantly. Here’s some suggestions on what to eat to get a great night’s sleep:
飲食對睡眠有很大影響。下面是幾條關(guān)于改善夜間睡眠的飲食建議：

Cut out caffeine 6 hours before you go to bed.
睡前6小時內(nèi)不喝含咖啡因飲品。

Stop drinking liquids 1 hour before bedtime.
睡前1小時不喝東西。

Skip the nightcap: It can make you fall asleep faster, but decreases sleep quality.

6. Wind Down and Clear Your Head
6.放松并清空大腦

冥想：冥想能使你冷靜下來，使你只能把注意力集中在一件簡單的事上：你的呼吸。只關(guān)注自己的呼吸——感覺空氣吸進(jìn)來，流經(jīng)全身，然后呼出去。
