Recently, the dispatch and command center of Beijing Emergency Medical Center received a coordinated emergency call transferred by the 110 reporting that several tourists at a bus stop were experiencing dizziness and severe discomfort and required immediate medical assistance. A nearby emergency medical team was dispatched without delay. As Beijing had issued a Yellow Alert for High Temperatures that day, the dispatcher, taking into account the extreme weather conditions, anticipated that the three tourists were likely suffering from heatstroke and informed the responding ambulance crew in advance. The ambulance arrived promptly at the scene. After asking about the circumstances leading to the incident and conducting on-site examinations, the emergency physician confirmed the dispatcher's preliminary assessment. Fortunately, all three tourists had only mild heat-related illness. Their symptoms improved after receiving professional treatment on site, and none were in life-threatening condition.

Beijing 120 reminds the public: As temperatures continue to rise during the summer, early warning signs such as dizziness, nausea, weakness in the limbs, and excessive thirst should never be ignored.

Move immediately: Leave the hot environment as soon as possible and rest in a cool, well-ventilated area. Loosen the clothing, especially around the neck, to help dissipate body heat.

Cool the body: Apply cool, wet towels to the forehead, neck, armpits, and other major cooling areas, and use a fan to promote heat loss.

Rehydrate properly: If the person is fully conscious, encourage them to sip lightly salted water, or an electrolyte drink slowly. Avoid drinking large amounts of ice-cold water all at once.

Seek emergency medical care promptly: If the person's body temperature exceeds 40°C or they develop loss of consciousness or seizures, call 120 immediately.

The public should also be aware of common misconceptions about heat prevention. Keeping doors and windows tightly closed at home while avoiding air conditioning, or remaining indoors during periods of high nighttime humidity, can also lead to indoor heatstroke, which is often overlooked. Residents are advised to avoid outdoor activities during the hottest part of the day, between 10:00 a.m. and 4:00 p.m. Outdoor workers should reduce the duration of continuous exposure to direct sunlight. Older adults, children, and people with chronic illnesses should pay particular attention to their physical condition, take appropriate heat-protection measures, and stay safe throughout the summer.
