Reacción a "Most indices that estimate the severity of a heatwave are insufficient, study finds"

The study compares six indices that seek to characterise extreme heat hazardous to our health, including humidity. The study concludes that the lethal heat stress index is more effective in identifying days with dangerous heat wave situations in low humidity environments, compared to the other indices. This was tested by analysing recent heat waves in Asia, the United States and Spain. 

The importance of the study is to highlight the urgency of conducting more in-depth analyses of what constitutes a deadly heatwave and how to prepare for them. This means studying in more detail the limits that the human body can withstand under various conditions, identifying those most at risk, and determining the measures needed to avoid fatal consequences, integrating knowledge from multiple disciplines.
