The rains are back — and with them comes a familiar mix of relief and risk. Yes, the rainy season cools things down, replenishes rivers and lakes, and helps farmers grow food. But it also brings muddy roads, damp homes, swarming mosquitoes, and a spike in infections. Fortunately, adopting smart rainy season habits can protect your health, keep your home safe, and help you stay productive through every downpour.
Here is what health and environmental experts recommend.
7 Rainy Season Habits That Actually Keep You Healthy
1. Prioritise Personal Hygiene
Public health expert Dr. Tunde Akintunde points out that wet weather creates perfect conditions for germs and infections to spread. His first line of defence? Wash your hands — often, and properly.
“One of the simplest but most effective preventive measures is frequent hand washing with soap and clean water,” he explained. “This helps reduce the risk of contracting common illnesses associated with the season.”
Beyond hand washing, Dr. Akintunde also stressed the importance of drying clothes, shoes, and personal items thoroughly after exposure to rain. Damp fabric, he noted, quickly becomes a breeding ground for fungal infections, skin irritation, and stubborn odours.
2. Keep Your Environment Clean
Good personal hygiene alone is not enough. Dr. Akintunde urged Nigerians to think beyond themselves and take responsibility for their immediate surroundings.
Blocked drains are a common culprit during the rainy season. When water cannot flow freely, it pools and stagnates — and stagnant water is a direct pathway to waterborne diseases. Clearing drains regularly, disposing of waste properly, and eliminating any conditions that allow water to collect will dramatically reduce health hazards in your home and neighbourhood.
3. Dress Smart for Wet Weather
This one sounds obvious, but many people still get caught off guard. Dr. Akintunde recommended lightweight yet protective clothing — think waterproof jackets, ponchos, and umbrellas for daily commuting. However, footwear deserves equal attention. Slippery surfaces are a leading cause of rainy-season injuries. Waterproof shoes or sandals with solid grip can prevent painful — and sometimes serious — falls on wet roads and floors.
4. Strengthen Your Immunity Through Nutrition
Malaria, colds, flu, and other infections surge during this time of year. One of the most effective — and underrated — rainy season habits is simply eating well.
Dr. Akintunde recommended a balanced diet rich in fruits, vegetables, proteins, and whole grains. Specifically, he highlighted foods packed with vitamins C and A — oranges, pineapples, carrots, and leafy greens like ugwu — as particularly powerful immune boosters.
“These foods support the body’s natural defence mechanisms,” he said. He also reminded Nigerians to drink enough clean water, even when cooler temperatures make thirst feel less urgent. Hydration remains critical regardless of the weather.
5. Protect Yourself from Mosquitoes
Environmental health expert Israel Adeyemi had a direct warning: every puddle, pot, and container collecting rainwater is a potential mosquito nursery. Stagnant water after rainfall is where mosquitoes breed, and that means the rainy season consistently drives up malaria cases across Nigeria.
His advice is practical and actionable. Empty any containers that collect standing water around your home. Sleep under treated mosquito nets. Fit your windows with insect screens. Apply insect repellent when going outdoors, especially in the evenings. According to the World Health Organization, malaria remains one of the leading causes of illness and death in sub-Saharan Africa — and most cases are entirely preventable.
6. Commute Carefully in Wet Conditions
Rainy roads kill. Adeyemi was blunt about this: reduced visibility and slippery surfaces make driving during heavy rainfall genuinely hazardous. He urged motorists to slow down, maintain safe following distances, and confirm that their headlights and windscreen wipers are working correctly before setting out.
For pedestrians, the message was equally clear — stay away from flooded areas and stay alert when crossing roads. Water on the surface can easily hide potholes, open drains, or other dangers beneath.
Preparing for a Healthier Rainy Season
7. Build Consistent Daily Routines
Both experts agreed that the most important thing is consistency. Individual habits matter, but they only work when practised regularly. Adeyemi summarised it well:
“Even though the rainy season has its own problems, if people adopt simple healthy habits, they will get through the season safely and comfortably. If we pay attention to how we keep ourselves clean, what we eat, how we maintain our environment, and how we protect ourselves, it will significantly reduce the sickness that usually follows the season.”
The rainy season, according to the European Wilderness Society, plays a vital ecological role — replenishing lakes and rivers, sustaining agriculture, and supporting biodiversity. Still, excessive rainfall can overwhelm drainage systems, destroy homes, and disrupt daily life in urban areas.
The good news is that smart preparation makes a measurable difference. Ultimately, staying healthy during the rainy season is less about luck and more about building the right habits before the storm arrives.
