This summer brought some uncomfortable nights when the temperatures soared amid the record-breaking heatwaves. On such evenings the last thing anyone wants is to be sweltering in bed under a thick duvet while they're trying to sleep, with a lighter covering much more appropriate - but the situation is about to be reversed.
The mercury will drop once autumn starts in earnest, meaning it will be time to swap light duvets for one with a higher tog rate which will be much cosier. And James Higgins, CEO of sustainable bedding company Ethical Bedding, has pinpointed the exact date when duvets such should be switched.
"It can be tricky to determine the best time to switch out our duvet tog as the temperature transition in September can be quite sporadic with unexpected heat waves coupled with night-time temperature drops," said James. "Changing too soon means you could be left hot and restless, but wait too long and you will feel the chill."
