For some weeks now, people in Lagos and Abuja have been groaning under the relentless heat, with temperatures soaring to unbearable levels.
But let’s not kid ourselves; everywhere in Nigeria is hot and this is driving people uncomfortable, prompting some to liken the ordeal to hell and others to plea for divine intervention.
So, what’s these heat waves and why are we experiencing it now?
Meaning of Heat Wave
A heat wave is a period of exceptionally hot weather, usually lasting for several days or even weeks, with temperatures much higher than usual for a particular time and place.
During a heat wave, the temperature stays consistently high, often making it uncomfortable and potentially dangerous for people and animals.
Prolonged exposure to such scorching conditions can lead to heat-related illnesses such as cramps, exhaustion, and even heat stroke, which can be fatal.
In Maiduguri back in 2002, a devastating heat wave claimed over 60 lives, yet these events often fly under the radar compared to other disasters.
What Cause Excessive Heat Waves in Nigeria?
Well, it’s partly down to our growing urban population.
Urban areas with extensive pavement and buildings absorb and retain more heat than rural areas. This phenomenon, known as the urban heat island effect, can exacerbate heat waves in cities, making them hotter than surrounding areas.
With half of Nigerians now living in cities, and Lagos alone Increasing with around 20 million residents ā equivalent to the populations of Malawi and Liberia combined ā urbanization is paving over natural vegetation, which helps keep temperatures in check.
Concrete-walled buildings, tarred roads, and heat-emitting vehicles further exacerbate the situation.
Other reasons include;
- High-pressure systems: Sometimes, a high-pressure system can settle over an area, leading to sinking air and clear skies. This atmospheric pattern traps heat near the surface, causing temperatures to soar.
- Climate change: Human activities, such as burning fossil fuels and deforestation, release greenhouse gases into the atmosphere. These gases trap heat, leading to a rise in global temperatures and increasing the frequency and intensity of heat waves.
- Weather patterns: Certain weather patterns, such as persistent ridges in the jet stream or stagnant air masses, can contribute to the development and prolongation of heat waves.
- Natural climate variability: Natural climate patterns, such as El NiƱo and La NiƱa events, can influence temperature patterns and contribute to the occurrence of heat waves in certain regions.
How to Survive Heat Wave
- Stay indoors during the hottest part of the day, typically from late morning to early evening. If possible, use air conditioning to keep your home cool. If you don’t have air conditioning, consider spending time in air-conditioned public places like malls or libraries.
- Drink plenty of water throughout the day, even if you don’t feel thirsty. Avoid drinks with caffeine or alcohol, as they can dehydrate you.
- Wear lightweight, loose-fitting clothing made of breathable fabrics like cotton. Light-colored clothing can also help reflect sunlight and keep you cooler.
- Close blinds or curtains during the day to block out direct sunlight. Use fans to circulate air and create a breeze indoors.
- Take cool showers or baths to lower your body temperature. You can also use wet towels or ice packs to cool yourself down.
- Avoid strenuous outdoor activities, especially during the hottest part of the day. If you need to be outside, take frequent breaks in the shade and drink plenty of water.
- Check on elderly relatives, neighbors, and anyone else who may be vulnerable to heat-related illnesses. Make sure they have access to a cool environment and are staying hydrated.
- Reduce alcohol intake as it could cause dehydration.
