TRENGGALEK – Transitional season health risks are rising as unpredictable weather increases the spread of viruses and bacteria, local health officials have warned.
Indonesia’s pancaroba, or transitional season, often brings sudden changes in temperature and humidity. These shifts can weaken the immune system and make people more vulnerable to illness.
Dr. Sunarto, head of the Trenggalek Health, Population Control and Family Planning Agency (Dinkesdalduk KB), said unstable weather can affect public health. The impact becomes more noticeable during Ramadan, when many Muslims observe fasting.
“Unpredictable weather can weaken the immune system,” Sunarto said. “As a result, people become more vulnerable to illnesses such as flu, colds, and respiratory infections.”
He added that changes in temperature and humidity also create conditions that allow viruses and bacteria to spread more easily.
Several diseases commonly appear during the transitional season. These include acute respiratory infections (ARI), flu, colds, dengue fever, asthma, allergic rhinitis, and digestive disorders.
To stay healthy during the seasonal shift, Sunarto urged residents to maintain a healthy lifestyle. He advised people to consume balanced and nutritious meals.
He also recommended drinking enough water, exercising regularly, and getting adequate sleep.
“People should aim to rest for around seven to eight hours each night to maintain a strong immune system,” he said.
Sunarto also stressed the importance of maintaining personal and environmental hygiene. Managing stress levels is equally important.
For Muslims observing Ramadan, he advised paying attention to nutrition during suhoor and iftar. Balanced meals and enough water help maintain energy during fasting hours.
He also suggested doing light exercise before breaking the fast.
“People should avoid foods that are too spicy or high in fat,” he added.
Sunarto further encouraged residents to undergo regular health check-ups. He also urged people to participate in vaccination programs to prevent disease during the transitional season.
