As temperatures rise during the summer, getting a restful night’s sleep can become increasingly difficult. Experts suggest that excessive heat can negatively impact both the quality and duration of sleep, particularly affecting the deep sleep that is crucial for body recovery and feeling rejuvenated. Ideally, bedroom temperatures should be maintained between 16°C and 18°C, but when the room temperature exceeds 24°C, it often results in a restless night.
Thankfully, there are several easy changes you can make to keep cool and sleep better during a heatwave. Start by choosing bedding and a mattress that promote air circulation and prevent heat retention. Natural materials like wool, bamboo, and linen are excellent choices as they help wick moisture away from the body and maintain breathability, making them perfect for warm nights.
If purchasing a new mattress isn’t feasible, consider investing in a cooling mattress topper made from breathable materials to alleviate discomfort. Linen sheets and pillowcases are also recommended as they remain light and comfortable, even on humid nights. For a quick chill, try placing your pillowcases or lightweight pajamas in the freezer for 15 to 20 minutes before bed, which can make falling asleep easier when it’s hot.
Cooling duvets that regulate body temperature can help prevent overheating, and fans or air coolers with misting functions can effectively lower room temperatures to enhance comfort. Another useful method is taking a lukewarm shower about 30 minutes before bedtime; while an icy shower might seem tempting, cool water reduces body temperature without causing later discomfort.
To prevent bedrooms from heating up during the day, keep curtains and blinds closed, which is especially important for children and babies who may require lighter clothing and cooler environments for sleeping. Additional tips for coping with the heat include using facial mist sprays, wearing blackout sleep masks, and creating a makeshift cooling pack by freezing a hot-water bottle overnight. Although heatwaves can be disruptive to sleep, these small adjustments in bedding, room temperature, and bedtime habits can make summer nights more bearable.
