Dr. Brian Chen, a sleep-medicine physician at the Cleveland Clinic, is providing public guidance on improving sleep hygiene for adults and children [1].
Proper sleep environments directly impact physical health and the quality of restorative rest. Poor hygiene can lead to chronic pain and fragmented sleep, which affects daily cognitive function and long-term wellness.
Chen treats a variety of sleep disorders at the Cleveland Clinic in Cleveland, Ohio [1]. His clinical approach focuses on both the medical treatment of disorders and the optimization of the physical environment where patients sleep [2].
One primary factor in sleep quality is the temperature of the bedroom. According to Chen, the optimal temperature for sleep is between 65 °F and 68 °F, or 18 °C to 20 °C [3]. Maintaining this range helps the body regulate its internal temperature, which is necessary for deep sleep cycles.
Beyond temperature, Chen emphasizes the role of physical support. He specifically notes the necessity of a supportive pillow to maintain spinal alignment. "If your pillow is not supporting your neck and head, you’re likely to wake up with neck pain and poorer sleep quality," Chen said [2].
Chen's advice suggests that small environmental adjustments can mitigate common sleep disruptions. He encourages patients to evaluate their bedding and room climate as part of a broader strategy to manage sleep disorders [1].
As a specialist in both adult and pediatric sleep medicine, Chen continues to provide these guidelines to help patients avoid the pitfalls of poor sleep hygiene [2]. This includes regular assessments of when to replace pillows to ensure continued neck support [2].
“The best bedroom temperature for sleep is around 65 °F (18 °C) to 68 °F (20 °C).”
The focus on environmental variables like temperature and ergonomics suggests a shift toward holistic sleep hygiene as a first line of defense against sleep disorders. By quantifying the 'ideal' sleep environment, clinicians can provide patients with actionable, low-cost interventions before moving toward more invasive medical treatments.
