用科學實證的「認知洗牌法」，幫你的大腦
從焦慮模式切換到入睡模式。
Science-backed Cognitive Shuffle — guides your brain
from anxious mode into sleep mode.
你有沒有這樣的經驗：躺下來準備睡覺，腦袋卻停不下來——回想白天的對話、擔心明天的事情、 或是一遍又一遍地想著一件讓你困擾的事？這就是心理學上的焦慮反芻迴路（Rumination Loop）。 大腦在這個狀態下，會誤以為你還需要維持清醒來「解決問題」，自然無法入睡。
Have you ever lain in bed unable to stop thinking — replaying conversations, worrying about tomorrow, or looping over the same troubling thought? That is the rumination loop. Your brain, stuck in problem-solving mode, interprets this as a signal to stay awake and alert. Sleep becomes impossible.
認知洗牌法（Cognitive Shuffle）由西門菲沙大學（Simon Fraser University） 認知科學家 Luc Beaudoin 博士所提出。其核心原理是： 透過快速、隨機、彼此毫不相關的視覺意象， 主動「佔滿」你的思緒，讓大腦沒有空間繼續焦慮反芻。 當腦中的意象足夠隨機且缺乏邏輯連結，大腦就會判斷「沒有需要保持清醒的威脅」， 進而觸發入睡機制，讓你自然滑入夢鄉。
Cognitive Shuffle was developed by cognitive scientist Dr. Luc Beaudoin at Simon Fraser University. The technique works by rapidly streaming random, unrelated visual images through your mind — actively occupying your mental bandwidth so there is no room left for anxious rumination. When the imagery is sufficiently random and lacks narrative logic, the brain concludes there is nothing threatening enough to stay awake for, and sleep onset follows naturally.
「睡眠的入口不在於放鬆或清空思緒，而在於讓思緒隨機、無序——讓大腦找不到理由繼續保持清醒。」
"The entry point to sleep is not relaxation or emptying the mind, but randomness — giving the brain no reason to stay alert."

ZzzDeck 將這個原理轉化為一個簡單易用的工具：每隔數秒顯示一個隨機單字， 你只需閉上眼睛，在腦中想像這個詞所代表的畫面。 不需要任何技巧或事先練習，任何人都可以立刻上手。
ZzzDeck translates this principle into a simple tool: a random word appears every few seconds, and you simply close your eyes and visualize the image it represents. No technique or prior practice needed — anyone can use it immediately.
ZzzDeck 支援 13 種語言（繁體中文、英文、日文、韓文、西班牙文、法文、德文、義大利文、葡萄牙文、俄文、印地文、孟加拉文、印尼文）。選一種讓你感到自在的語言。
ZzzDeck supports 13 languages: Traditional Chinese, English, Japanese, Korean, Spanish, French, German, Italian, Portuguese, Russian, Hindi, Bengali, and Indonesian. Pick whichever feels most natural to you.
用滑桿設定每張卡片顯示的時間，範圍是 4 到 12 秒。建議從 6 秒開始，再依自己想像畫面的速度調整——不需要趕，讓每個意象在腦中稍微成形即可。
Use the slider to set how long each word is displayed — from 4 to 12 seconds. Start around 6 seconds and adjust to match your visualization speed. No rush; let each image take gentle shape in your mind.
點擊播放後，把手機或電腦放下，閉上眼睛。每當語音朗讀一個新單字，就在腦中想像那個東西的畫面——可以是顏色、形狀、材質、場景，越具體越好，但不需要強求。
After pressing play, put down your device and close your eyes. When you hear each new word, visualize it in your mind — colors, shapes, textures, scenes. The more vivid the better, but don't strain. Let images come naturally.
從四種環境音中選一種：雨聲、白噪音、咖啡廳聲、溪流聲。背景音效能遮蔽環境噪音，讓你更容易沉浸在意象中。這是選擇性的——不加也完全有效。
Choose from four ambient sounds: rain, white noise, café, or stream. Background sound masks environmental noise and deepens immersion. This is optional — the technique works without it too.
選擇 5、10、20 或 30 分鐘後自動停止播放。這樣你不需要擔心工具一直響，可以完全放鬆地等待入睡。大多數人在 10 分鐘內就會睡著。
Choose to auto-stop after 5, 10, 20, or 30 minutes. This way you don't need to worry about the tool running all night — just relax and drift off. Most people fall asleep within 10 minutes.
13 種語言的瀏覽器原生語音，不需要看螢幕，閉眼聆聽即可。
Native browser TTS in 13 languages. No need to look at the screen — just listen with eyes closed.
4 種循環播放的環境音（雨聲、白噪音、咖啡廳、溪流），遮蔽外部干擾。
4 looping ambient sounds (rain, white noise, café, stream) to mask external distractions.
設定 5 / 10 / 20 / 30 分鐘後自動停止，不用擔心工具整晚播放。
Auto-stop after 5 / 10 / 20 / 30 minutes. No worrying about it playing all night.
4–12 秒滑桿，按你自己的節奏想像畫面，不趕時間。
4–12 second slider so you can visualize at your own pace, without feeling rushed.

腦袋停不下來的人——躺下後五分鐘，腦子裡已經在開一場沒人邀請的會議。
Overthinkers — five minutes after lying down, your brain is already running an uninvited meeting.

冥想效果有限的人——試過冥想但「清空思緒」對你太困難，ZzzDeck 的方向完全相反：用意象填滿思緒，而不是清空。
Meditation skeptics — tried it, but "emptying your mind" is too hard. ZzzDeck is the opposite: fill your mind with imagery, don't try to empty it.
認知洗牌法有科學根據嗎？
Is Cognitive Shuffle scientifically supported?
有的。認知洗牌法由西門菲沙大學（Simon Fraser University）的 Luc Beaudoin 博士提出， 其核心理論已在認知科學文獻中記錄。方法基於「意象可以佔用前意識處理資源， 使大腦脫離反芻迴路」的認知機制。雖然不是每個人都有相同效果，但對許多苦於「躺下後無法關閉思緒」的人非常有幫助。
Yes. Cognitive Shuffle was developed by Dr. Luc Beaudoin at Simon Fraser University. The underlying theory is documented in cognitive science literature — imagery occupies preconscious processing resources, disrupting the rumination loop. Results vary by person, but many who struggle to "switch off" at night find it very effective.

語音朗讀（TTS）在我的手機上沒有聲音，怎麼辦？
The text-to-speech isn't working on my device. What should I do?
部分裝置（特別是 iOS Safari）的語音合成需要先有用戶互動（點擊操作）才能啟用。 請確認已先按下播放按鈕，再觀察是否有聲音。如果仍然無聲，可以關閉 TTS， 改用純視覺方式（看到單字後閉眼想像畫面）——效果同樣有效，因為核心是「視覺化意象」，不是聲音本身。
Some devices (especially iOS Safari) require a user interaction before speech synthesis can activate. Make sure you've tapped the play button first. If it still doesn't work, simply turn off TTS and use it visually — read the word, close your eyes, and visualize. The technique works the same way, because the key mechanism is the mental imagery, not the audio.

ZzzDeck 與冥想 App（如 Headspace、Calm）有什麼不同？
How is ZzzDeck different from meditation apps like Headspace or Calm?
冥想通常要求「清空思緒」或「專注於當下的感受」，這對許多人反而會造成壓力， 效果有限。認知洗牌法的方向完全相反：它用隨機意象填滿思緒， 而不是嘗試清空。兩者機制不同，也適合不同的睡眠問題。 如果你試過冥想但覺得「我根本做不到清空腦袋」，ZzzDeck 可能更適合你。
Meditation typically asks you to "empty your mind" or "focus on present sensation" — for many people this creates pressure and limited results. Cognitive Shuffle works in the opposite direction: it fills your mind with random imagery rather than trying to empty it. The two approaches target different mechanisms. If you've tried meditation and felt "I can't possibly empty my head," ZzzDeck may suit you better.
ZzzDeck 是醫療器材嗎？
