Overview
- Mexico’s national weather service warns the heat wave will persist across wide regions with some areas likely topping 45 °C, including parts of Ciudad de México, Chihuahua, Coahuila, Guanajuato, Querétaro, Sinaloa and Tamaulipas.
- Doctors describe heat stroke as a rapid rise in body temperature that the body cannot shed, which can quickly injure the brain, heart, kidneys and other organs if not treated at once.
- Key human warning signs include 39–41 °C fever, hot and dry or then absent sweating, red skin, confusion, dizziness, severe headache, vomiting and convulsions.
- Health officials urge prevention with steady hydration, light clothing, shade, staying indoors during 11:00–15:00, and extra care for children under 6, adults over 65, people with obesity and those on medications.
- Veterinarians caution that dogs and cats can suffer fatal heat stroke, noting early panting that worsens, red gums or tongue, vomiting or diarrhea, and later collapse or seizures, and they advise immediate cooling with water and airflow, small sips of water and urgent transport to a clinic while avoiding ice-cold water.
