While the “dry season” in Nigeria is known to bring with it extreme temperatures, this year’s heat seems to be on a different level. Well, that is because what we are experiencing is more than just heat. We are experiencing what is called Heatwave.

What is Heatwave?

A heatwave can simply be defined as the period of heightened temperature or hot weather which may be accompanied by high humidity. With increasing hotness of the atmosphere, it becomes unbearable with profuse perspiration.

In addition to Heatwave increases body temperature which affects the central nervous system and circulatory system causing exhaustion, fainting, and heat syncope. This article covers the risk factors, health implications and ways to manage it.
