As temperature soars and humidity levels rise, the concept of "heat index" emerges as a crucial means of understanding the impact of hot weather on society. Heat index refers to the ambient air temperature and the level of humidity an average person feels. In regions like the Philippines, where extreme heat waves are becoming increasingly common, the heat index serves as a vital tool in assessing the severity of heat-related risks.
This surge of heat is expected to last until mid-May, with the temperature hitting a record high, especially in the capital city of Manila. The heat index has reached dangerous levels in at least 30 cities and municipalities across the country. Many schools have been forced to suspend face-to-face classes, and health authorities have issued advisories concerning heat-related illnesses.
When the heat index is between 42 and 51 degrees Celsius, it will be classified as "dangerous" because it can lead to different conditions such as heat fatigue, cramps, and heat exhaustion. According to the Philippine State Weather Forecaster's Chief Climatologist, there is a 50% possibility that the heat will intensify in the days to come. This is alarming given that the Philippines is among the countries most at risk from climate change.
To decrease the consequences of the intense heat index in the Philippines, a comprehensive strategy should be implemented immediately. The country must always be prepared for extremely hot weather conditions and ensure healthier sustainable communities in the future by putting up ecological infrastructure, advocating for environment-friendly means of transport, improving energy efficiency in buildings, and making use of alternate sources of power while sensitizing the public.
