Rainfall in Colombia: how to strengthen your immune system and avoid illness, according to experts

The intense rains that have returned to the country mark a new cycle of precipitation that, according to Ideam, could last until December.

This phenomenon, influenced by Tropical Storm Melissa , the fifth potential hurricane of the season, has raised concerns among specialists due to the increase in respiratory, digestive, and allergic diseases that often accompany prolonged downpours.

Given this situation, experts recommend strengthening the body's defenses and adopting preventative routines both inside and outside the home.

Scientist Hugo Palafox, an expert in human metabolism, antioxidants, and cellular nutrition, explained to El Colombiano that “during this time of year, the body faces greater challenges in staying healthy and balanced, making it more susceptible to viral illnesses.” He added that the humid climate and temperature changes directly affect the body's natural defenses , thus requiring a more conscious self-care routine.

Among his main recommendations, the specialist emphasized the importance of keeping humidity under control inside homes . “It’s important to check for leaks or stagnant water, as excessive humidity promotes mold growth and can trigger allergies and respiratory infections,” he warned. He also advised ventilating spaces, cleaning gutters, and monitoring areas prone to flooding.

Palafox pointed out that prevention begins with diet, as it is the cornerstone of the immune system. “Consuming fruits and vegetables rich in vitamin C, maintaining good hydration, and cooking food properly are key to reducing the risk of disease,” she stated. She also recommended including nutritional supplements that stimulate the natural production of glutathione , an antioxidant molecule that the body produces to protect cells from damage and strengthen defenses against viruses and bacteria.

Along these lines, Palafox highlighted the importance of glutathione, an antioxidant molecule that the body produces naturally to protect cells from damage and maintain strong defenses. She also emphasized that no single method can replace healthy habits or medical guidance : “It’s about combining strategies, not replacing basic care like nutrition and rest.”

Palafox emphasized that mild symptoms should not be ignored . “If respiratory, digestive, or muscular discomfort persists for more than a few days, it’s best to consult a doctor. Don’t wait for the condition to worsen, because rain tends to prolong infectious processes,” he added.

His final message was clear: “Following these recommendations strengthens the body and creates habits that ensure long-term well-being. In seasons with more volatile weather, our health should receive preventative, not reactive, attention.”

During the rainy season, it's common for cases of flu, colds, and other infections to increase. This happens because humidity, cold weather, and sudden temperature changes weaken the immune system , making it easier for respiratory viruses and bacteria to spread.

To avoid this, experts recommend maintaining healthy habits that strengthen the body's natural defenses. Getting enough sleep, staying properly hydrated, and engaging in moderate physical activity help maintain the body's balance in the face of changing weather.

If symptoms such as cough, fever, or general malaise appear, it is important not to self-medicate . Ideally, stay warm and see a doctor if the discomfort lasts more than a few days, in order to receive a timely diagnosis and prevent complications.
