Urban Heat Survival: A Complete Guide to Preparing for Extreme Heatwaves
Practical advice on heat-proofing your apartment, understanding wet-bulb temperatures, and avoiding heat exhaustion during summer peaks.
The Danger of Urban Heat
As temperatures rise, cities become heat traps due to concrete, asphalt, and lack of green space. Knowing how to survive extreme heatwaves is critical.
1. Understanding Wet-Bulb Temperature
The wet-bulb temperature measures the combined effect of heat and humidity. When wet-bulb temperatures exceed 95°F (35°C), the human body can no longer cool itself through sweating, making it dangerous to stay outdoors.
2. Insulating and Cooling Your Space
Keep blinds closed during the day to block direct sunlight. Use reflective window films or foil-lined cardboard on south-facing windows. If you don't have AC, set up fans to create cross-breezes at night.
3. Recognizing Heat Illnesses
Know the signs of heat exhaustion (heavy sweating, weakness, dizziness) and heat stroke (high body temp, red skin, confusion). Heat stroke is a medical emergency.
