Overview
- Sinave confirmed Yucatán’s first death from heat stroke in late June and reported 59 people affected in the state, including 43 heat‑stroke cases, 11 cases of dehydration, and five sunburns.
- The federal weekly report through epidemiological week 24 shows 920 cases and 30 deaths nationwide in the 2026 heat season, a 25 percent rise in deaths compared with the same point in 2025.
- Health officials say most deaths (28 of 30) have been caused by heat stroke, which clinicians define as body temperature above about 40°C and a medical emergency requiring hospitalization.
- Authorities warn that high humidity in the peninsula reduces the body’s ability to cool itself and that children under five, older adults, outdoor workers, and people with chronic conditions face the highest risk.
- Officials are urging simple measures to prevent more cases: continuous hydration, avoiding sun exposure in the hours of greatest radiation, wearing light clothing and sunscreen, and following Protección Civil and SMN advisories.
