Europe is battling a severe heatwave, with temperatures soaring to near-record levels across the Mediterranean. Tourists and locals alike are struggling to cope with the extreme conditions, particularly in popular destinations like Spain, Italy, and Greece.

The United Nations' World Meteorological Organization (WMO) has warned about the dangers of persistently high nighttime temperatures, which hinder the body's ability to recover from the heat, leading to a heightened risk of health issues like heart attacks.

The current heatwave coincides with peak tourist season, disrupting travel plans and forcing many to seek refuge from the scorching sun. In Rome, visitors flocked to fountains and cooling stations set up near landmarks like the Colosseum. The influx of tourists combined with the extreme heat has created challenging conditions for both travelers and residents.

Dr. Marc Siegel, a clinical professor of medicine, emphasizes the need to consult a doctor about any medications that could exacerbate sun or heat sensitivity. He also advises prioritizing hydration, replacing electrolytes, and seeking cooler coastal areas rather than inland historical sites.
