Top 8 Health Effects of Flooding in Nigeria

Flooding is a common natural disaster that kills people around the world, and Nigeria is no different. Every year, parts of the country experience some form of flooding, which has caused significant property damage and displaced many people. Flooding causes more than just physical damage, like drowning and the loss of property. It also poses many health risks. This article looks at how flooding affects people’s health in Nigeria and how the Nigeria Hydrological Services Agency (NIHSA) works to reduce these risks.

Nigeria has a big problem with flooding, which affects many states on a regular basis. In 2012, 30 out of 36 states in Nigeria were affected by floods, according to the National Emergency Management Agency (NEMA). The Nigerian Hydrological Services Agency (NIHSA) monitors flood levels and issues alerts to warn people of potential flooding.

In places like Lokoja, the NIHSA has issued a red alert, which means that the flood water level is high and that people should leave flood-prone areas to avoid disasters caused by flash floods and trans-boundary river flows. It is important for people to heed these warnings and take steps to protect themselves and their property from the damaging effects of flooding.

Possible Health Effects of Flooding in Nigeria

Flooding is a common and often devastating natural disaster in Nigeria, with the potential to cause significant physical and health impacts. In addition to the obvious risks of drowning and physical injury, flooding can also lead to a range of other health hazards. In this blog post, we will explore some of the most significant health effects of flooding in Nigeria and what you can do to protect yourself and your loved ones.

1. Drowning

One of the most immediate and obvious health risks associated with flooding is drowning. Flood waters can rise quickly and unexpectedly, making it difficult for people to escape to higher ground. Even relatively shallow water can be dangerous if you are not a strong swimmer, and fast-moving flood waters can sweep you off your feet. It is important to be aware of the risks and to avoid entering flood waters whenever possible.

2. Physical injuries

In addition to the risk of drowning, flooding can also lead to physical injuries such as cuts, bruises, and broken bones. These injuries can be caused by falling, being hit by debris, or being swept away by the water. It is important to be cautious and avoid unnecessary risks when in a flood-affected area.

3. Contaminated water

Flooding can also have serious implications for the health of the general population. Contaminated water is a major concern, as flood waters can carry sewage, chemicals, and other harmful substances. Ingesting contaminated water or coming into contact with it can lead to serious illness, including diarrhea, cholera, and other waterborne diseases. It is important to use caution when consuming water or food that may have been in contact with flood waters, and to seek medical attention if you become ill after being in a flood-affected area.

4. Mosquito-borne diseases

Another significant health risk associated with flooding is the proliferation of mosquitoes, which can carry diseases such as malaria and dengue fever. Standing water provides an ideal breeding ground for mosquitoes, and the risk of these diseases increases after a flood. It is important to take steps to protect yourself from mosquito bites, such as using insect repellent and sleeping under a mosquito net.

5. Mental health problems

The disruption and uncertainty caused by a flood can also lead to mental health problems such as post-traumatic stress disorder (PTSD), anxiety, and depression. These conditions can be treated with therapy and medication, and it is important to seek help if you are struggling after a flood.

6. Respiratory problems

The damp, humid conditions that often occur after a flood can create a breeding ground for mold and other respiratory irritants. This can lead to respiratory problems such as asthma and allergies, especially for those who are already prone to these conditions. It is important to take steps to dry out and ventilate flood-affected areas to reduce the risk of mold growth.

7. Heat exhaustion

In the hot, humid conditions that often accompany a flood, it is important to stay hydrated and take breaks to avoid heat exhaustion. Symptoms of heat exhaustion include dizziness, headache, and muscle cramps, and it can lead to more serious conditions such as heat stroke if left untreated.

8. Mental health impacts

Finally, flooding can also have serious mental health impacts, as it can cause stress, anxiety, and depression. The loss of property, loved ones, and personal possessions can be devastating, and the aftermath of a flood can be a challenging and overwhelming time. It is important to take care of your mental health during this time and to seek support if you need it.


In conclusion, flooding can have significant physical and health impacts in Nigeria. It is important to be aware of the risks and to take steps to protect yourself and your loved ones. This includes avoiding flood waters, being cautious to avoid physical injury, being mindful of contaminated water and food, taking steps to protect against mosquito bites, and taking care of your mental health. By taking these precautions, you can help to minimize the health risks associated with flooding and ensure that you and your loved ones stay safe during this challenging time.
