TL;DR
As heatwaves become more frequent due to climate change, many struggle to sleep in hot nights. This article provides 13 evidence-based tips and product suggestions to improve sleep quality during high temperatures.
As heatwaves become more frequent across Britain, millions are facing difficulty sleeping through hot nights. Experts confirm that elevated temperatures significantly reduce sleep quality, especially deep sleep stages, making rest harder to achieve during warm weather.
Sleep specialist Dr. Allie Hare states that high bedroom temperatures over 24°C can cause restlessness and impair sleep, while the ideal range is around 16-18°C. To combat this, experts recommend using cooling products such as breathable linen bedding, natural-fibre mattresses, and cooling toppers. Additionally, practical tips include cooling bedding in advance, taking lukewarm showers before bed, and blocking out sunlight with blackout blinds or sleep masks.
Several products have been tested for effectiveness. The Millbrook Wool Luxury mattress was praised for its natural wool layers that help regulate body temperature, while bamboo toppers and moisture-wicking linens are also popular. Fans with misting functions, like the Dreo TurboCool, can lower room temperatures by several degrees, and cooling duvet covers with phase change materials help prevent overheating. For children, keeping rooms dark and dressing them in light clothing or nappies is advised.
While these measures can improve sleep, experts note that individual responses vary and some solutions may work better than others depending on circumstances. It is also acknowledged that climate change will likely increase the frequency of heatwaves, making such strategies increasingly necessary.
Why Staying Cool at Night Is Crucial for Health
Good sleep is essential for overall health, cognitive function, and well-being. With climate change driving more frequent and intense heatwaves, understanding effective ways to stay cool during sleep is increasingly important. Poor sleep during heatwaves can exacerbate health issues, impair productivity, and reduce quality of life. Implementing these cooling strategies can support better rest and help mitigate some adverse effects of rising temperatures.

Heatwaves and Sleep: Growing Challenges in a Warming Climate
Climate scientists project that heatwaves will become more common and severe in the coming decades, especially in regions like Britain where summers are warming. While sleep disturbances during hot nights are well-documented, recent studies highlight the need for practical, accessible solutions. Experts like Dr. Hare emphasize that despite the body’s natural mechanisms to cool down, external aids are often necessary to improve sleep quality during extreme heat.
“Being too hot during sleep can significantly reduce sleep quality and duration, especially affecting deep sleep stages.”
