As one of the most revered songwriters of all time, it's somewhat unlikely that Leonard Cohen would have been referring to an intriguing night's sleep during the summer, on Closing Time.
“… the moon is swimming naked / And the summer night is fragrant / With a mighty expectation of relief.”
Nonetheless, nobody can ignore the importance of attaining high-quality sleep throughout the year, and especially, during the warmer summer months.
Indeed, during the winter, your bedroom is often your only haven - the one place you can be guaranteed comfortability, warmth and rest. But then, once the colder months have passed, your bedroom is suddenly unable to provide you with that same level of assurance. Whereas it was once your refuge at the end of a hard day's work, the bedroom can quickly become a place of sleepless nights and misery, more similar to a sauna than a safe space.
Obviously, it’s not all about being too hot. For example, over 24°C and below 12°C have been shown to significantly contribute to more fractured, lighter rest, and our optimal temperature for sleep is approx. 16 – 18°C.
Reaching such a temperature in your bedroom or home would be relatively simple with something like a thermostat.
Otherwise, we wanted to tell you about some of those products that can aid in providing you with that cooling relief you've been searching for, and can actively help you reduce and/or regulate your body temperature, and feel more comfortable for high-quality slumber even on the hottest nights.

Night-focused products support skin recovery while you sleep, when your skin is most effective at repairing.
Higher ambient temperatures—especially above 24°C—can disrupt your body's natural thermoregulation process, making it harder to fall and stay asleep. Additionally, longer daylight hours and increased humidity can further reduce sleep quality by preventing the core body temperature drop required for restful sleep.
The optimal sleeping temperature is between 16–18°C . At this range, your body can cool down effectively, promoting deeper and more restorative sleep. Using thermostats, fans, or cooling bedding can help achieve this range even during heatwaves.
The most recommended summer bedding materials are:
Cotton percale : Lightweight, crisp, and breathable.
Linen : Highly absorbent and temperature-regulating.
Eucalyptus or bamboo fibers : Moisture-wicking, cool to the touch, and hypoallergenic.
Look for duvets between 2–7.5 tog to avoid overheating.
Cooling pillows like the Kally Sleep Cooling Pillow or Tempur SmartCool Pillow are engineered to dissipate heat and enhance airflow. These can significantly reduce sweating and restlessness caused by warm heads or necks.
The right sleepwear can dramatically improve comfort. Choose lightweight, breathable fabrics such as:
Organic cotton or NATTCOOL™ Tencel blends
Styles like short-sleeve tops, camisoles, and shorts
Avoid heavy, synthetic materials that trap heat and moisture.
Use light, hydrating skincare that won’t clog pores or feel greasy. Look for serums and oils with ingredients like vitamin C, E, aloe vera, rosehip oil , and lightweight gel moisturisers. Cooling or marine-based night creams can help skin recover from heat exposure.
Take a lukewarm (not cold) shower to encourage body heat release
Use a chilled water bottle at your feet or neck
Sleep in breathable, moisture-wicking bedding
Keep curtains closed during the day to block heat buildup
Use cross-ventilation with fans or slightly open windows if safe
