The sleep Foundation article "The Best Temperature for sleep" discusses how bedroom temperature affects sleep quality. It recommends maintaining a bedroom temperature around 65°F (18.3°C), with a suggested range between 60-67°F (15.6-19.4°C), to support the body's natural thermoregulation during sleep. A cooler environment facilitates the body's core temperature drop, promoting better sleep onset and maintenance. The article also notes that individual preferences may vary, and adjustments should be made accordingly.Maintaining an optimal sleep environment is crucial for brain health and cognitive performance, as quality sleep enhances memory consolidation and cognitive functions. To improve sleep quality, it's advisable to keep the bedroom cool, use breathable bedding, and establish a consistent sleep routine. Given the sleep Foundation's expertise and the evidence provided, these recommendations are credible and practical for enhancing sleep and cognitive health.
