The World Health Organization (WHO) has warned of a new wave of extreme heat that will hit Europe in the coming days. According to experts, there may be "even more deadly weeks" ahead if authorities do not take additional measures to protect the population. Weather forecasts predict that this week, temperatures in Portugal and southern Spain could reach **43 degrees**. Hans Kluge, Director of the WHO European Regional Office, stated that one of the main problems remains the insufficient preparedness of many countries for such weather events. "The most alarming fact is that even half of the countries in the European region still do not have a national action plan to protect public health during abnormal heat," he noted. According to Kluge, many residents do not realize they are at risk, even when authorities declare the highest level of weather danger. WHO experts also urged an increase in the number of public cooling centers and better inform people about their locations, especially the homeless and other socially vulnerable citizens. Another issue the organization highlights is the delays in officially declaring a heat emergency in several countries. This can slow down the implementation of necessary measures and increase the burden on the healthcare system. Experts are particularly concerned about the situation of residents in nursing homes, the homeless, and lonely elderly people, who often remain without the necessary assistance during extremely high temperatures. WHO reminds that abnormal heat remains one of the most dangerous natural factors for human health. Timely warnings, access to cooled spaces, and special attention to at-risk groups can significantly reduce the number of severe consequences and save lives.
