Close the blinds and windows
Closing blinds and curtains once the air gets cooler the night before – and keep them that way until the heatwave is finished.
By simply not letting the direct sunlight in, it’s possible to stay reasonably cool.
The Heatwave Plan for England advises to keep blinds down and windows shut during the day.
It says: “Keep windows that are exposed to the sun closed during the day, and open windows at night when the temperature has dropped.”
Elsewhere, it says: “Windows and other ventilation openings should not be closed, but their openings reduced when the outdoor air becomes warmer than the air indoors – this should help keep rooms cool whilst allowing adequate ventilation.”
