The rainy season brings welcome relief from the heat, but it also creates conditions that make colds, catarrh, cough, and other respiratory infections more common.
Introduction
The rainy season in Nigeria is often accompanied by cooler temperatures, frequent rainfall, and increased humidity. While many people enjoy the refreshing weather, this period also sees a rise in cases of catarrh, cough, sore throat, flu-like illnesses, and other respiratory infections.
Contrary to popular belief, cold weather itself does not cause the common cold. Rather, viruses spread more easily when people spend more time indoors in close contact with one another, and the body’s natural defenses may be affected by changes in temperature and humidity.
The good news is that there are practical steps you can take to reduce your risk of falling ill during the rainy season.
Why Are Colds More Common During the Rainy Season?
People often gather indoors to avoid the rain, making it easier for viruses to spread through coughing, sneezing, or close contact.
Wet clothing, poor ventilation, fluctuating temperatures, and weakened immunity due to poor nutrition or inadequate sleep can also increase susceptibility to illness.
Protecting yourself requires a combination of good hygiene, proper nutrition, and healthy lifestyle habits.
Simple Ways to Stay Healthy This Rainy Season
The following measures can help reduce your risk of developing catarrh, cough, flu-like illnesses, and other seasonal infections.
1. Keep Warm and Dry
Getting caught in the rain is sometimes unavoidable, but remaining in wet clothing for long periods can make you uncomfortable and may contribute to a drop in body temperature.
If you get soaked, change into dry clothes as soon as possible. Wear appropriate clothing when going out, especially during early mornings and evenings when temperatures are cooler.
2. Wash Your Hands Regularly
Many viruses that cause colds and flu spread through contaminated hands and surfaces.
Wash your hands frequently with soap and clean water, especially after returning home, before eating, after coughing or sneezing, and after using public transportation. If soap and water are unavailable, use an alcohol-based hand sanitizer.
3. Eat Foods That Strengthen Your Immune System
A strong immune system is one of your best defenses against infections.
Include plenty of fruits, vegetables, whole grains, legumes, lean proteins, and healthy fats in your diet. Foods rich in vitamin C, zinc, and antioxidants, such as oranges, guavas, pineapples, spinach, tomatoes, and beans, can help support normal immune function.
4. Stay Hydrated
Many people drink less water during cold weather because they do not feel as thirsty. However, adequate hydration remains essential for overall health.
Drinking enough water helps maintain healthy mucous membranes in the nose and throat, which act as the body’s first line of defense against invading germs.
5. Get Enough Sleep
Quality sleep allows the immune system to function effectively.
Adults should aim for seven to nine hours of sleep each night, while children require even more. Poor sleep can make it harder for the body to fight infections.
6. Exercise Regularly
Moderate physical activity improves circulation and supports immune health.
Even when it is raining, simple indoor exercises such as stretching, dancing, skipping rope, or home workouts can help keep your body active and healthy.
7. Practice Good Respiratory Hygiene
Cover your mouth and nose with a tissue or your elbow when coughing or sneezing to reduce the spread of germs.
Dispose of used tissues properly and wash your hands immediately afterward. Avoid touching your face unnecessarily, especially your eyes, nose, and mouth.
8. Keep Your Living Space Well Ventilated
Although it may be tempting to keep all doors and windows closed during rainy weather, poor ventilation can allow viruses to circulate more easily indoors.
Whenever possible, allow fresh air to circulate through your home or workplace while keeping rainwater out.
9. Avoid Close Contact with Sick Individuals
Respiratory viruses spread easily from person to person.
If someone around you has a cold, cough, or flu-like symptoms, maintain reasonable distance where possible and avoid sharing drinking cups, utensils, towels, or personal items.
10. Seek Medical Care When Necessary
Most common colds improve within a week or two with rest, fluids, and supportive care. However, persistent or severe symptoms should not be ignored.
If you experience high fever, difficulty breathing, chest pain, prolonged cough, or symptoms that worsen instead of improving, consult a qualified healthcare professional promptly for proper evaluation and treatment.

Foods That Can Help During the Rainy Season
Warm soups prepared with vegetables and lean protein provide nourishment and comfort. Citrus fruits such as oranges are rich in vitamin C, while ginger and garlic add flavor and contain compounds that may support normal immune function.
Yogurt contributes beneficial probiotics for gut health, and adequate protein from fish, eggs, beans, or poultry helps maintain a healthy immune system.
While no single food can prevent illness, a balanced diet gives your body the nutrients it needs to function at its best.
Common Myths About Cold Weather
Many people believe that cold weather directly causes catarrh or the common cold. In reality, viruses are responsible for these infections. Cold weather may create conditions that make transmission easier, but exposure to low temperatures alone does not cause a viral infection.
Similarly, taking antibiotics will not cure a common cold because antibiotics only work against bacterial infections, not viruses. Antibiotics should only be used when prescribed by a qualified healthcare professional.
Final Thoughts
Nigeria’s rainy season brings cooler temperatures and much-needed rainfall, but it also increases the likelihood of respiratory infections such as colds, catarrh, and flu-like illnesses.
Fortunately, protecting yourself does not require complicated measures. Simple habits such as eating a balanced diet, staying warm and dry, washing your hands regularly, sleeping well, exercising, and seeking medical care when necessary can significantly reduce your risk of becoming ill.
