The UK is experiencing another heatwave, making it increasingly difficult to fall asleep as brick-built homes retain heat. Many people resort to various hacks, such as frozen water bottles, damp socks, or cold showers, but one expert advises against a common practice: taking a cold shower before bedtime.
Why Cold Showers Are Counterproductive
Sammy Margo, a sleep expert at Dreams, explains that cold showers can make the body feel more alert, prompting it to "wake up" rather than wind down. Instead, she recommends a lukewarm shower. "A lukewarm shower helps lower your core body temperature gradually when you step out of it, triggering your body’s natural cooling process and promoting relaxation," she said.
The Importance of Quality Sleep
Getting adequate sleep is crucial for overall health. According to John Hopkins Medicine, chronic poor sleep may increase the risk of dementia, heart disease, type 2 diabetes, obesity, and certain cancers. The NHS advises that adults need seven to nine hours of sleep per night, children nine to 13 hours, and toddlers and babies 12 to 17 hours. The NHS warns that constant daytime tiredness may indicate insufficient sleep.
Additional Tips for Sleeping in a Heatwave
Beyond showering, Margo suggests keeping the bedroom calm, quiet, and dark. Social media users on Reddit shared their own tips, including keeping windows closed during the day and opening them when outdoor temperatures drop below indoor levels, misting bed sheets with a spray bottle, and using air conditioning units.
