Stay Active During Rainy Season: Indoor Exercise and Health Management Guide
Rainy season makes outdoor exercise difficult. Discover effective indoor workouts and health tips to stay fit during the wet months.
Japan's rainy season (tsuyu) typically runs from early June to mid-July, lasting 40-50 days. The combination of rain, humidity, and low air pressure makes it easy to fall into physical inactivity. Here's how to stay fit and healthy throughout the wet season.
How Rainy Season Affects Your Body
Low Pressure Effects
As atmospheric pressure drops during rainy season, the vestibular system in the inner ear responds, disrupting the autonomic nervous system. This leads to headaches, fatigue, and joint pain in old injuries.
High Humidity and Fatigue
When humidity is high, sweat doesn't evaporate efficiently. Your body works harder to regulate temperature, leading to increased fatigue even without physical activity.
Reduced Sunlight and Mood
Less sunlight means reduced serotonin production, contributing to low mood and motivation.
