你是否有這種經歷，平時飽受失眠之苦，但一坐上搖搖晃晃的長途大巴、地鐵或飛機就昏昏欲睡，忍不住打盹。不過，在公共交通工具上睡覺既不安全也不舒適。
最近，香港一家旅行社專為失眠人士打造了睡眠巴士之旅，這條旅遊線路全程76公里，車程5小時，遊客可以乘坐雙層巴士在睡夢中環遊香港。
“When we were brainstorming new tours, I saw a social media post from my friend saying that he was stressed out by his work, he couldn’t sleep at night,” said Kenneth Kong, the marketing and business development manager of ulu travel, the organizer of the bus tours.
睡眠巴士的組織者、ulu travel旅行社市場和業務發展經理肯尼思·顧表示：“我們一起討論新的旅遊專案時，我看到我朋友在社交媒體上釋出的帖子，說他工作壓力太大，晚上睡不著覺。”
“But when he was traveling on the bus, he was able to sleep well. His post inspired us to create this tour that lets passengers just sleep on the bus.”
“但在乘坐巴士時他就睡得很好。他的帖子給了我們靈感開設這個專門讓乘客在車上睡覺的旅行專案。”

Tickets cost between $13 to $51 per person, depending on whether they choose seats on the upper or lower deck. A goodie bag for passengers includes an eye-mask and ear plugs for better sleep.
睡眠巴士的單人票價在13美元到51美元（約83元到326元）之間，票價取決於座位在上層還是下層。旅行社會為乘客準備眼罩和耳塞，以便他們享受更優質的睡眠。
The first “Sleeping Bus Tour” last Saturday sold out entirely. Some passengers came prepared, bringing their own blankets and changing their shoes to slippers, while others brought travel pillows.
10月16日，“睡眠巴士之旅”首次開售車票就全部售罄。一些乘客有備而來，自己帶著毯子，換上拖鞋，還有乘客帶著旅行枕頭。
“I have been suffering from insomnia so I am here to try and get some sleep,” said 25-year-old Anson Kong, one of the passengers on the first bus tour.
25歲的安森·顧是首趟“睡眠巴士之旅”的乘客，他說：“我一直失眠，所以來這裡試著睡一覺。”
He said that the tour was a good idea and “more interesting” than he expected.
顧先生表示，這個點子不錯，比他預期的“更有趣”。
On Saturday’s tour, the bus stopped so passengers could take photos at scenic spots on the city’s Lantau Island.
當天，睡眠巴士在行程中停車，以便乘客可以在香港大嶼山的景點拍照。
Another passenger, Marco Yung, said that he joined the tour because he usually falls asleep on long-distance bus journeys, saying it was a “great opportunity” to get some sleep.
另一位乘客馬可·翁說，參加這次旅行是因為自己常常在長途汽車旅行中睡著，他說這是一個“睡覺的好機會”。

為什麼一坐車就犯困？
遊客們對這趟旅行的評價都十分滿意，睡眠巴士似乎比臥室的大床更適合入睡。汽車座椅究竟有什麼神奇的催眠魔力，為什麼許多人一坐上車就容易犯困呢？Smart Sleeping Tips網站總結了幾個原因：
1.White noise
白噪音
Cars and other vehicles are a perfect environment that produces white noise. It’s a consistent noise, like the hum of tires or the purring of the car. White noise masks distracting sounds, and is helpful for people who have trouble getting sleep.
汽車和其他車輛是產生白噪聲的完美環境。它是一種始終如一的噪聲，如輪胎的嗡嗡聲或汽車的嗚嗚聲。白噪音掩蓋了分散注意力的聲音，對睡眠困難的人很有幫助。
When you’re riding a vehicle, white noise is continuously emitted, making it easier for passengers to drift off to dreamland.
當乘客坐在車上時，白噪音會不斷地釋放出來，使人們更容易進入夢鄉。
2.Rocking motion
搖晃
Another popular view as to why it’s easy to fall asleep in buses or trains is because of the rocking motion that’s similar to what lulled us to sleep when we were babies.
另一種流行的觀點認為，在公共汽車或火車上很容易入睡是因為搖擺，這種搖擺類似於我們還是嬰兒時被哄睡的動作。
However, it’s not the rocking movement, per se, that induces sleep. Rather, it’s the association between rocking and sleeping. If you were rocked to sleep as a baby, you’d have that association that when you experience a rocking motion, you go to sleep.
然而，並不是搖擺動作讓人入睡，而是搖擺和睡眠之間的聯絡。如果你在嬰兒時被搖晃著入睡，你就會把搖晃的動作和入睡聯絡起來。
3. Increase in carbon dioxide in public transportation
公共交通工具內的二氧化碳增加
Buses and trains get crowded everyday with people going to and from work. Carbon dioxide increases when there are lots of people in a small space. This reduces oxygen to the brain and slows it down.
公共汽車和火車每天都擠滿了上下班的人。當一個狹小的空間裡有很多人時，二氧化碳濃度就會增加。這會減少大腦中的氧氣並讓大腦變得遲緩。
你也會在車上打盹嗎？
