Block the sun early
Close blinds or curtains on sun-facing windows before direct sun reaches the glass. Exterior shade works best; even a temporary awning or balcony shade can reduce the heat that builds indoors. Keep reflective materials safely secured and follow your building’s rules.
Let cooler air do the work
When outdoor air is cooler than inside, open windows on opposite sides if you can. A fan placed to draw warm air out of a window can help; keep another opening available for replacement air. Close up again as the day warms.
Make one cool room
Choose the shadiest room, reduce heat from ovens and appliances, and keep water within reach. A cool shower, damp cloth, or time in a public cooling space can help when your home stays hot. Check local heat guidance for symptoms that need urgent care.
Pick the sunniest window. Set a reminder to close its curtains before the afternoon sun arrives.
Look out for one another
Agree on a check-in with a neighbor, friend, or family member before a heat spell. Older adults, young children, and people with some health conditions can be more vulnerable to heat.
