Can’t Sleep in the Heat? These 8 Tricks Could Save Your Night

As the UK swelters through its hottest summer on record, many Brits are struggling to get a good night’s sleep. With temperatures soaring and humidity levels off the charts, it’s no wonder that sleep suffers. The science behind thermoregulation – our body’s ability to regulate its internal temperature – tells us that sleep and heat are closely linked.

When our bedroom becomes a sweltering oven, our body struggles to cool down, making it harder to drift off to dreamland. And with the UK’s increasingly hot summers, this problem is only set to worsen. The Met Office reports a 20 times greater chance of exceeding 40°C in the UK than in the 1960s. With a 50% likelihood of another 40°C day within the next 12 years, it’s clear that our summers are becoming a whole lot hotter.

While air conditioning might be the ultimate solution, it’s not an option for many households – and certainly not a practical or affordable one. The Energy Saving Trust estimates that a small portable air-conditioning unit would cost around £54.83 in electricity alone, before even buying the unit.

Instead of relying on costly mechanical cooling solutions, homeowners can rethink their approach to keeping homes cool. Shading and ventilation have long been effective ways to reduce indoor heat without breaking the bank. These passive cooling strategies work by reducing the amount of heat entering our homes through windows and external shading devices, creating a cooler environment that’s easier on the body.

Cross-ventilation also makes a big difference. By opening windows or doors on different sides of the home to let cool air in, we can reduce indoor temperatures. For example, if your bedroom is situated on an upper floor or faces south or west, it’s likely one of the hottest rooms in the house – and with good reason. Heat rises through buildings, and sun-facing walls and roofs can continue releasing stored heat long after sunset.

If relocating your bedroom to a cooler floor or orientation isn’t feasible, there are still plenty of other ways to stay cool. Using fans wisely, choosing breathable bedding and clothing, and being mindful of heat-producing appliances that can make indoor spaces even warmer can all help reduce heat gain in the home.

Extractor fans are also an effective way to remove warm, moist air from kitchens and bathrooms before it spreads throughout the home. Research has shown that these fans can significantly reduce moisture movement between rooms, making it easier for sweat to evaporate and our bodies to cool down.

In addition to these strategies, homeowners can also consider using light-colored curtains or blinds to reflect sunlight and keep their homes cooler. Planting trees or installing awnings on south-facing walls can also help shade windows and reduce heat gain.

By shifting our focus from mechanical cooling solutions to passive strategies like shading and ventilation, we can create homes that are not only cooler but also more sustainable. The long-term benefits of these changes will be well worth it – better sleep, reduced energy bills, and a healthier relationship with our environment.
