Sleep Expert Warns: Switch to a Low Tog Duvet This Summer or Risk Sleepless Nights
With the UK set for heatwaves this week, Senior Sleep Expert at MattressNextDay, Martin Seeley, is highlighting the importance of switching out their bedding to avoid night sweats and disrupted sleep, especially as Loughborough University found that over 4.6 million UK bedrooms overheat in summer.
Martin Seeley, Senior Sleep Expert at MattressNextDay urges people to switch out their bedding amidst warmer temperatures across the UK:
“When summer arrives, many of us instinctively throw open the windows and swap out our wardrobe, but we often forget that our bedding needs a seasonal update too. Night sweats, disrupted sleep, and that sticky feeling of overheating are all signs that your current set-up might not be suited to warmer temperatures. One of the most effective and immediate changes you can make is switching to a low tog duvet. Anything around 4.5 tog is typically sufficient for summer, offering just enough coverage without trapping unnecessary heat.
“Material choice plays a crucial role as well. Natural fibres like cotton, bamboo, and linen are particularly effective in hot weather due to their breathable, moisture-wicking properties. Cotton is soft and accessible, while bamboo is naturally antibacterial and excellent for temperature regulation. Linen, with its looser weave, allows air to circulate freely, making it a great option for anyone prone to overheating. These materials not only help keep you cooler but also create a fresher, cleaner sleep environment over time.
“Beyond the duvet and sheets, your overall bedding strategy should support airflow and temperature regulation. A breathable mattress protector can help prevent heat build-up from below, while pillowcases made from the same lightweight fabrics can reduce facial overheating, which is a common cause of sleep disturbance. It is also worth noting that synthetic materials, while often less expensive, tend to trap heat and moisture, which can make warm nights feel even more uncomfortable.
“Ultimately, your summer sleep set-up should feel effortless and light, both physically and sensorially. Think of it not as stripping back comfort but as refining it to suit the season. Investing in breathable, well-matched bedding allows your body to do what it is naturally designed to do: adjust, cool down, and rest deeply. Good sleep is foundational to wellbeing all year round, and in summer, small changes can have a remarkably big impact.”
