眠活

• 読み: みんかつ
• ローマ字: minkatsu
• 漢字の分解: 眠 (sleep, slumber) + 活 (activity, life, pursuit) → sleep optimization activity
• 発音: /miɴ.ka.tsu/

意味

Sleep optimization activity — the deliberate practice of improving sleep quality through environment, habits, and products.

眠活 is the newest addition to Japan's ○○活 wellness trends, reflecting growing awareness that sleep is fundamental to health. Japan is notorious for being one of the most sleep-deprived nations — average sleep time is among the lowest in OECD countries. 眠活 practices include optimizing bedroom environment (lighting, temperature, bedding), establishing pre-sleep routines (reducing screen time, using aromatherapy), and using sleep-tracking apps and devices. Premium mattress brands, sleep-focused supplements, and 'sleep coaching' services have all emerged.
