As the Met Office forecasts highs of 38°C this week, Brits are being urged to take advantage of the heatwave to wash their duvets. With temperatures soaring, many will discard their duvets at night, making it an ideal time to clean them. Thick covers can increase dehydration overnight, so removing the duvet altogether or switching to a summer version is recommended.
Why Wash Your Duvet During the Heatwave
Duvets accumulate bacteria, sweat, and dust mites over time. The hot weather provides an opportunity to wash and dry them efficiently. According to Good Housekeeping, drying a duvet outside in the sun is easier and more effective than using a tumble dryer, especially for those with care labels that advise against machine drying.
Kim Hawley, a senior tester for sleep and wellness, told Good Housekeeping: “When temperatures climb, it can be tempting to sleep in your birthday suit, but lightweight pyjamas made from natural or cooling fabrics can actually help you stay more comfortable. Breathable materials, such as cotton, bamboo and moisture-wicking fabrics, draw sweat away from the skin, helping you feel cooler throughout the night.”
How to Wash Your Duvet Properly
For duvets with a tog rating of 13.5 or higher, or anything larger than king-size, experts recommend taking them to a laundrette. Otherwise, check the care label before washing. Use the highest recommended temperature with a low to medium spin cycle, and opt for liquid detergent at a third of the usual amount. Adding an extra rinse cycle ensures all detergent is removed.
Alternative Bedding for Hot Nights
While the duvet is being washed, Brits can use weather-appropriate bedding. Summer duvets are available for those who prefer a layer, but many find that sleeping without a duvet is cooler. The heatwave also helps rooms stay cooler by keeping windows shaded and using fans.
By washing duvets now, Brits can improve sleep hygiene and be prepared for cooler nights ahead. The Met Office's heatwave warning makes this the perfect time to tackle this household chore.
