The SAMU061 emergency service has reported a sharp rise in calls related to heat-related illnesses. Between June and July alone, the service handled around 600 cases, with approximately 1,600 consultations logged since the start of the year. Heatstroke incidents have also increased, with 26 suspected cases recorded during this summer so far, four of which have been confirmed, including one fatality. Last year, only one heatstroke case was confirmed, affecting a ten-month-old infant.
Medical director Txema Álvarez highlighted the impact of the recent heatwave, which saw temperatures exceeding 40ºC in the shade. “The number of calls has surged, mostly due to headaches, dizziness, and overexposure to the sun, whether on beaches, walking trails, or in workplaces exposed to the heat,” he explained. He added that heatstroke occurs when the body reaches around 40ºC and neurological symptoms, such as confusion and convulsions, appear following prolonged sun exposure.
Heat-related illnesses encompass a range of symptoms, including nausea, vomiting, rapid heartbeat, low blood pressure, and general weakness. Those most at risk are people aged over 70, particularly women, as well as infants and individuals with certain pre-existing conditions. Around half of older patients who suffer severe heat-related symptoms require hospital treatment, often involving intravenous hydration.
To minimise risk, experts advise maintaining good hydration, consuming water-rich foods, and staying in cool or air-conditioned environments where possible. Outdoor activities should be scheduled for cooler parts of the day, and physically demanding sports should be avoided during peak temperatures. “Some professions, such as construction, deliberately avoid working in the hottest hours,” Álvarez noted.
Authorities continue to urge residents and visitors on the Islands to be vigilant during the ongoing heatwave. With extreme temperatures expected to persist, taking simple precautions such as regular hydration, shade breaks, and limiting strenuous activity can help prevent serious heat-related illness.
