寒暖差不調 (kandansa fucho), also known as 寒暖差疲労 (kandansa hiro), is a condition where the body experiences fatigue and discomfort due to rapid temperature changes. This is considered a type of "weather sickness" and often occurs when the temperature difference exceeds 7°C. The body's autonomic nervous system struggles to adapt to these fluctuations, leading to symptoms like fatigue, headache, stiff shoulders, and dizziness. To combat this, staying warm from the inside and outside, such as avoiding cold drinks and dressing in layers, is recommended.
