Nigeria’s Quiet Health Crisis: When the Heat, the Floods, and Our Silence Start Making Us Sick – By Kehinde Kenku

Something is happening to us. You can feel it in the air.

The heat last year was not the kind you complain about and move on. It was heavy. Stubborn. It sat on your skin even when the fan was on full speed. Even air conditioners seemed tired. People said, “This heat is different.” And it truly was.

This isn’t just weather acting up. It is climate change. Real. Present. And dangerously ignored.

Nigeria is in the middle of a health emergency, though we hardly call it that. It shows up in overcrowded hospitals. In recurring malaria. In strange skin irritations after a bath. In children coughing through dry nights. The signs are everywhere, but we connect them slowly, if at all.

Take harmattan for instance. We grew up knowing its timetable. December comes, the air turns dusty, lips go dry, sweaters come out. Simple. Predictable. But in December 2025, harmattan did not show up. It delayed. Then appeared briefly in January 2026, stayed for barely two days, and vanished. That is not a minor shift. That is a climate system losing its rhythm.

And when the climate loses balance, so do we.

Heat and humidity now create the perfect playground for mosquitoes. Malaria cases are rising, even in homes that do “everything right.” I know this personally. Fumigation done. Environment clean. Nets used. Yet malaria returns. Two times. Sometimes three times in weeks. It begins to feel less like bad luck and more like exposure we cannot escape.

Because it is.

Warmer temperatures help mosquitoes breed faster. They worsen hypertension. They stress the body. In the North, intense heat and dryness fuel meningitis outbreaks. In other regions, floods leave behind stagnant water, and suddenly cholera and typhoid enter the conversation again. These are not isolated incidents. They are patterns.

Now add poor drainage to the story.

Many Nigerian communities either have no proper drainage or the ones available are blocked with refuse. Houses are built on waterways with little planning. When heavy rain falls, the water has nowhere to go. It settles. It waits. Mosquitoes arrive. Disease follows. It becomes a public health crisis, though we call it “just flooding.”

Waste management makes it worse. Uncollected garbage piles up on streets, inside gutters, beside homes. When rain falls, it carries contamination into groundwater. The smell pollutes the air. The water many depend on becomes questionable. And yet we treat waste as an eyesore, not a health threat.

Then there is water itself. Something so basic. So essential.

In many homes, boreholes are poorly regulated. Sewage systems leak quietly underground. Even treated water can cause itching, stomach upset, strange reactions. People start to wonder why “clean” water doesn’t feel clean. Access to safe water should not be a gamble, but for many Nigerians, it is.

So yes, Nigeria has a health crisis. It may not look dramatic on the surface. No loud sirens. No official declaration. But it is unfolding daily, slowly, persistently.

The most troubling part? Awareness is still low. Many people hear “climate change” and think of melting ice somewhere far away. Not their street. Not their child’s recurring fever. Not their mother’s worsening asthma. The disconnect is costing us.

Government responses feel slow. Scattered. Policies are discussed in conferences, written in documents, filed away. On the ground, drainage systems remain broken. Waste management remains inconsistent. Climate adaptation feels more like a buzzword than a plan.

Of course, individuals can try. We clear our surroundings. We boil water. We use mosquito nets. We buy medications. But personal effort cannot replace functioning infrastructure. It cannot substitute for environmental accountability. There is only so much one household can do.

This crisis is not waiting for the future. It is already here. In the heat waves. In the floods. In the hospital bills that keep repeating themselves.

And if climate action, environmental governance, and public health planning continue to move at this slow pace, Nigerians will keep paying. Not in theory. In blood pressure readings. In infections. In lives quietly shortened.

That price is too high.

And honestly, we have delayed long enough.
