Protect people, routines and the home during extreme heat.
Heat becomes dangerous when the body cannot cool down and the home no longer releases heat at night. Preparedness combines hydration, cooling routines, vulnerable-person checks and home adaptation.
Confusion, fainting, very hot skin, persistent headache, nausea or unusual fatigue can signal heat illness. Move the person to a cooler place and seek medical help when symptoms are severe or persistent.
Watch both people and the building.
Heat risk is not only an outdoor temperature. It depends on humidity, night cooling, ventilation, vulnerability and the way the home stores heat.
Organize the day and night cycle.
The goal is to block heat during the day, release it at night and keep people hydrated and cooled progressively.
Reduce heat gain before the next episode.
External shade and passive cooling are often more robust than relying only on emergency reactions.
