• 漢字の分解: 自 (self) + 律 (regulate, law) + 神 (spirit, god) + 経 (passage, nerve) → self-regulating nervous system

意味

Autonomic nervous system; often referenced in the context of stress-related imbalance causing various physical symptoms.

自律神経 has become one of the most frequently cited health concepts in Japan, used as a catch-all explanation for a wide range of stress-related symptoms: headaches, fatigue, insomnia, digestive issues, dizziness, and mood swings. 自律神経の乱れ (autonomic nervous system imbalance) is invoked by health media, doctors, and everyday people alike. While medically legitimate, the term is sometimes overused as a vague explanation for any unexplained symptoms.

例文

1. 最近疲れが取れないの、たぶん自律神経乱れてると思う。
2. 季節の変わり目は自律神経が乱れやすいんだって。
3. 自律神経整えるために毎朝日光浴びるようにしてる。
