Immediate Actions to Take During Extreme Heat
When temperatures soar to dangerous levels, every minute counts. The weather agency advises that indoor spaces without air conditioning can be just as dangerous as being outdoors. Here are critical steps to follow:
- Stop all outdoor activities immediately when a heat warning is issued.
- Move to an air-conditioned environment, such as a shopping mall, library, or cooling center.
- Stay hydrated by drinking water frequently, even if you don’t feel thirsty.
- Check on vulnerable neighbors, especially the elderly and young children.
- Use fans or mist-spray zones if air conditioning is unavailable.
Comparing Heatwave Responses: South Korea vs. Other Countries
Different nations have varying approaches to extreme heat. The table below compares South Korea’s current strategy with those of other heat-prone regions.

| Aspect | South Korea | United States | Japan |
|---|---|---|---|
| Emergency Alert System | New category for heatwaves (introduced 2023) | Heat advisories and warnings by NWS | Heat stroke alerts by JMA |
| Public Guidance | Stop all outdoor activities | Limit outdoor exposure, use cooling centers | Encourage indoor stay and hydration |
| Cooling Infrastructure | Mist zones, public AC spaces | Cooling centers in many cities | Air-conditioned public facilities |
Health Risks and How to Recognize Heatstroke
Heatstroke is a medical emergency that can be fatal. Symptoms include high body temperature, confusion, rapid pulse, and loss of consciousness. If you or someone else shows these signs, call emergency services immediately. While waiting, move the person to a cooler place and apply cool cloths.
Prevention is better than cure. Avoid strenuous activities during peak heat hours (11 a.m. to 4 p.m.), wear light-colored and loose clothing, and never leave children or pets in parked cars.
Long-Term Strategies for Heatwave Resilience
As heatwaves become more frequent and intense due to climate change, communities must adapt. Installing energy-efficient air conditioners, improving building insulation, and planting trees for shade are effective measures. On a personal level, consider creating an emergency kit with water, electrolytes, and portable fans.
