認知洗牌法（Cognitive Shuffle）是加拿大西門菲莎大學 Luc Beaudoin 博士提出的助眠技術。原理是透過想像一系列隨機、不相關的畫面，打斷大腦在睡前常見的焦慮反芻循環——讓大腦無法維持清醒時的線性思考，自然滑入睡眠狀態。詳細介紹請參考我們的文章：為什麼我睡不著？

有。認知洗牌法有同行評審的理論基礎（「睡眠期望理論」），並且有初步臨床研究支持其有效性，包含 2023 年的隨機對照試驗。然而大規模研究仍在進行中，效果因人而異。它最適合「腦子停不下來」型的入睡困難，對睡眠呼吸中止症等生理性睡眠問題幫助有限。

認知洗牌法通常需要 3–7 次練習才開始見效。如果嘗試 2 週仍無改善，可以嘗試搭配白噪音或進行呼吸練習。如果失眠持續超過 3 個月（每週 3 次以上），建議諮詢醫師或睡眠專家，評估認知行為治療失眠（CBT-I）。

Cognitive Shuffle is a sleep technique developed by Dr. Luc Beaudoin at Simon Fraser University. It works by having you visualize random, unrelated images in sequence — disrupting the anxious thought loops that often keep people awake. The random imagery prevents the brain from maintaining the linear, problem-solving thinking associated with wakefulness, helping it transition into sleep. Read more: Why Can't I Sleep?

Cognitive Shuffle typically requires 3–7 practice sessions before it starts working consistently. If you don't notice improvement after 2 weeks, try combining it with white noise or a breathing exercise. If insomnia persists longer than 3 months (3+ nights per week), consult a doctor or sleep specialist about CBT-I (Cognitive Behavioral Therapy for Insomnia).
