 Nigeria has been in a grip of an intense heat wave over the past few months, as climate change experts say there won't be a relief if NASA's reactions are not taken to tackle climate change. The weather condition, which began in the month of February, may have exposed many Nigerians to a number of health risks. Plus, TV News health correspondent Ngozi Kaohai-Chesey has more in this report. In Nigeria, the drizzles usually start from the month of March to April every year. However, this year, there have been extreme hot and humid weather nationwide, even in coastal areas such as Lagos, hitting the streets, residents of Lagos complain about the unbearable heat. There's no, even though if you have fun, say, if nothing will work for you, I say use your hands when you find yourself, come outside. Sometimes we spend nights outside to deep breath because of the heat. Hot nights and afternoons, the weather is so high, maybe this is the end of the life, I don't know. We are feeling the hot weather, but there is nothing we can do with it because there are no green lights, so that is why we cannot sleep well in the night in the house. We don't have choice because every pleasure there is by virtue that we can sleep better because if you can't see, find it is too much. See all my neck like this, for it is because we have to buy the petrol and we want it for the, to the second day. So I'm not okay. Medical and climate change experts warn against the dangers to human and natural resources. Dr. Tsu-Yu Meba Wendu, a public health expert for over three decades, speaks about the major risk factors of heat and preventive measures to take during this period. The purpose of sweating is to provide a cooling system because once you sweat and the water evaporates, it cools your body. That is the purpose of the sweat. So now you have to sweat excessively. When you sweat excessively, you lose nutrients, you lose electrolytes, you lose water. So now, if the water is not replaced, you become dehydrated. I mean, what it means is that the water in your body then falls down to the low certain level, which becomes a problem for the body. It can have effect on the cardiovascular system, the proper of your heart. It has effect on the kidney function and even your mood and emotion. These are, of course, with the heat, you are prone to rashes, okay? Because, you know, the heat rush and infection thereof can be additional problem. So you also observe that people that experience it, they cannot actually do work as they ought to do it. They have labile mood. Their mood just swings anyhow. They get angry easily and they are prone to rash decisions. So apart from the thing having effect on the body, it has effect on the productivity of the person and even the productivity of the country or the city as a whole. If you are not a dog, stay under shade, okay? Trees, houses, bus stops, you know, that's where you can stay. Always take sufficient fluid, okay? Along. Philip Chapo is a climate change expert. He calls on the government to take action against gas emission, bush burning, car exorption and other human activities that pollute the earth. If we move away from those things, start looking at, like I said earlier, the mass transit trains that will take people a long distance. Like the government is doing, but we don't see too much commitment. Like Lagos State is trying to do, but it's neither here nor there. If we have that nationally, so that I don't need to drive my car every morning or evening and then I have to enter the train or the metro that will take not just me, but many other people. I think those little, little contributions are there to, for instance, planting more trees because in the city Lagos is concrete jungle. Just like Wari is, just like Potacot is, just like Abuja is. These are, we, Abuja is very beautiful. That's what everybody says, but Abuja like Lagos is a concrete jungle. There are no trees anyway. These trees will assimilate as much, you know, as we put into the atmosphere and then cool the atmosphere. But, you know, this is Lagos. That's Abuja, that's Wari, Kaduna. Most parts of the country, you don't have the green cover that will ameliorate what we are passing through. When you go out there in the sun, there's no shade. So you take all the dangerous rays coming from the sun and no protection. According to the UN Climate Science Panel, the world needs to rapidly accelerate its transition away from coal and other fossil fuels to avoid extreme climate change. However, Nigeria has place to reduce its greenhouse gas emission by 20% by 2030 with the condition of 45% of international support. Nga Zika or HSE. Class TV News.
