With more warm nights ahead, you might find it harder to go to sleep, and might be tempted to ditch all your clothes. But apparently, you shouldn't sleep naked during a heatwave.09:52, 28 May 2026Updated 09:52, 28 May 2026As the May heatwave continues, making the most of the warm temperatures in the garden during the daytime can prove relaxing - but when it's time for bed it can prove a real struggle. Falling asleep when it's hot can be hard, and hot sticky nights can become uncomfortable - even with the windows open and a beside fan.‌With temperatures once again in the high 20s across the UK today (May 28), by tonight it may be tempting to just strip off and sleep without anything on. However, experts have warned that you shouldn't ever sleep naked.‌Speaking on YouTube, the Love And Love Factory asked: "Ever wondered if sleeping naked during a heatwave is a good idea?" They then proceeded to explain why it's actually the "worst choice".‌"You think shedding clothes helps you stay cool, but the opposite is true," they elaborated. "Without any fabric, sweat clings to your body."Love and Love Factory continued: "Sleeping naked can disrupt your sleep cycle. You might lose more water from sweating. This can lead to dehydration overnight. Clothing can actually absorb that sweat, keeping you cooler."‌Instead, you should opt to wear "light, breathable fabrics", which will help keep moisture away from your skin. "That helps with the evaporation of cooling," they added. "Light pyjamas can actually help you feel cooler."Speaking on behalf of Kudd.ly, meanwhile, Suzy Reading, a psychologist who specialises in well-being, backed up the advice."I'd recommend opting for loose fitting, airy, light garments in natural fibres such as cotton, silk, eucalyptus or bamboo," she said.‌"I wouldn't recommend sleeping naked, as much as this might appeal, because sweat then collects on your skin rather than being absorbed by the fibres of your clothing and cooling you down."Suzy continued: "In addition to your own body temperature dropping when you sleep, ambient temperature can also drop at night, so light sleepwear will keep you more comfortable and promote better sleep."The immediate forecast from the Met Office states: "Early showers across northern and eastern areas will fade, leaving most places dry with prolonged sunshine on Thursday. Cloud will increase over parts of England and Wales, bringing a few showers later, possibly thundery. Widely very warm, feeling hot in the southeast."Article continues belowThe forecast continues: "Tonight - evening showers slowly clearing eastwards. Cloudy with outbreaks of rain affecting parts of Northern Ireland and Scotland, otherwise dry with clear spells. Another warm night, especially in the east."Friday - dry with sunny spells for most, however outbreaks of rain will affect the far north, with showers across the southeast, where it will be another very warm day. Cooler elsewhere."An earlier version of this story was published in July 2024.
