Entering the rainy season of 2026 The weather changes frequently, increasing the risk of catching a cold. Thairath Online recommends 9 ways to prevent colds during the rainy season and health care tips to strengthen immunity to handle all weather conditions.
When the rainy season arrives, temperature and humidity often change rapidly. According to data from the Department of Disease Control, Ministry of Public Health, the damp and cool weather creates conditions that allow viruses causing respiratory diseases, such as common colds and flu, to thrive and spread more easily. Additionally, getting wet in the rain lowers body temperature, which weakens the immune system’s efficiency, making the body more susceptible to infections.
Proper health care during the rainy season requires changes in daily habits, as follows:
You should always carry an umbrella, raincoat, or hat in your bag to prevent your body, especially your head, from being directly exposed to raindrops, which is a main cause of rapid body temperature drop.
If you cannot avoid walking in the rain, once you arrive home or at your accommodation, promptly take a shower and wash your hair. Then dry and blow-dry your hair completely to reduce germs and prevent colds.
Hands come into contact with many surfaces. Washing them regularly with soap and clean water or using alcohol gel helps reduce the risk of viruses entering the body through touching your face, eyes, nose, or mouth.
Consuming fruits rich in vitamin C, such as oranges, guava, Indian gooseberry, or kiwi, helps strengthen the immune system to better fight viruses.
Drinking at least 8 glasses of room temperature water daily helps maintain body temperature balance and supports normal waste elimination functions.
Sleeping at least 7-8 hours a day is the best way to restore the body and immune system. Lack of rest increases the risk of infection.
Find time to exercise at least 30 minutes per day, 3-5 days a week, such as indoor aerobics or yoga, to stimulate blood circulation and boost immunity.
During heavy rain, people often gather in shelters or crowded locations like BTS stations or shopping malls, where close contact and poor ventilation increase the risk of respiratory virus spread. Wearing masks in public spaces offers additional protection against infections.
Humidity during the rainy season promotes mold and bacteria growth inside homes. Open windows for air circulation and sunlight when weather permits, and regularly clean air conditioners and bedding to reduce allergens that weaken the respiratory system and increase susceptibility to colds.
Preventing colds during the rainy season 2026 is not difficult if we consistently take care of ourselves by preventing dampness, maintaining cleanliness, and choosing nutritious foods. With these steps, you can confidently face the rainy season and stay healthy throughout.
