European heatwaves heighten cardiac and mental health risks

Experts warn that rising summer temperatures across Europe increase strain on the cardiovascular system. A 2023 U.S. study recorded more than 2,300 heat‑related deaths, and another analysis projects that fatal heat‑linked heart incidents could more than double in the next decade. The heat forces the heart to work harder, raises pulse rate, and can lead to dehydration, prompting recommendations to avoid outdoor activity during the hottest hours, stay hydrated, wear light clothing and seek shade or cool indoor spaces.

Heat also aggravates mental‑health conditions. Prolonged exposure to extreme heat can worsen anxiety, depression and panic symptoms, especially for individuals taking antidepressants such as SSRIs, SNRIs or tricyclics, which may impair temperature regulation. Experts note a feeling of entrapment when people cannot escape the heat, adding psychological stress. They advise ample fluid intake, cooling living areas, regular meals, sufficient sleep and careful monitoring of medication effects during heatwaves.
