The Met Office has shared a simple curtain trick that takes just seconds to keep upstairs rooms cooler during the UK heatwave. Upper-floor rooms are typically five to 15 degrees warmer than the rest of the property, with the master bedroom often the hottest due to its height and large windows.
Why Upstairs Is Hotter
The temperature difference is due to basic science: as air warms, its molecules spread apart, making it lighter. Warm air rises to the second floor, while cooler air stays downstairs. This natural process can lead to uncomfortable sleeping conditions if left unaddressed.
The Met Office stated that maintaining a cool home is "one of the most effective ways" to cope with elevated temperatures during the current heatwave in Britain.
The Simple 5-Second Task
The weather specialists advise households to close curtains or blinds in rooms that face the sun. This helps prevent heat from building up indoors. Window coverings act as barriers against the sun's warmth, keeping upstairs less humid and airless. If you lack curtains or blinds, draping a bedsheet or towel can achieve a similar result.
Additional Tips for Keeping Cool
While it may seem counterintuitive, experts recommend shutting windows and doors during the hottest part of the day to retain cooler air inside. In the evening, as temperatures drop, opening windows can ventilate the home and allow cooler air to circulate.
Leaving all internal doors open is also advised to boost airflow on the upper floor. Otherwise, warmth becomes confined to specific rooms, making them feel like saunas. Airflow is the most effective method for maintaining a cool house.
