In the UK’s current heatwave conditions, some people report sleeping less comfortably and waking up feeling hot and sticky. Two outlets cite cleaning expert Lynsey Crombie, also known as the “Queen of Clean,” to explain when to wash bedding during high temperatures. The guidance focuses on how heat can affect sweat and hygiene, which in turn can make bedding feel less fresh sooner than usual. Crombie’s advice highlights specific items such as pillows and mattress protectors, indicating these components should be washed more frequently in warm weather to reduce buildup associated with perspiration. While the articles frame the recommendations around the practical experience of disturbed sleep and increased sweating during hot nights, they do not describe any single national standard for laundering frequency beyond the expert’s suggested timing for heatwave conditions. Overall, the reports present the same premise: warmer temperatures increase the need for regular cleaning of key bedding items to maintain freshness and hygiene.
