Beware of 'June sickness' during rainy season, Japanese doctor advises

As Japan enters its rainy season, a doctor is warning of a condition known as "June sickness," a mental health challenge linked to seasonal changes and accumulated stress.

Dr. Takashi Mogi of Bandai Medical Clinic explains that after enduring two months of intense effort following new academic or work starts in April, many individuals experience a mental fatigue that surfaces with the onset of the rainy season. This can manifest as adjustment disorders and autonomic nervous system imbalances.

Symptoms commonly include profound depression on Sunday evenings, extreme difficulty getting out of bed in the morning, and a general reluctance to face work or school. Dr. Mogi attributes these feelings to factors like the low atmospheric pressure during the rainy season, reduced sunlight impacting serotonin levels, and rapid temperature and humidity fluctuations that strain the body's ability to adapt. The lack of public holidays in June also contributes to a feeling of distant vacation time, hindering fatigue recovery.

Dr. Mogi advises that those who are typically diligent and responsible are often more susceptible. He stresses the importance of adequate rest and self-compassion, encouraging people to tell themselves, "It's okay not to try too hard." Simple actions like opening curtains to sunlight in the morning can boost serotonin, while moderate exercise can help regulate the autonomic nervous system.

He emphasizes that "June sickness" is a genuine physical and mental response, not mere laziness. Individuals experiencing persistent fatigue lasting over two weeks without fever, or insomnia and frequent waking for over 10 days, should seek professional medical advice for early treatment.
