For years, 78 degrees Fahrenheit was the commonly recommended bedroom temperature for sleep, but a fresh survey of over 2,000 adults across the US sets the new standard much lower at 67 degrees. This cooler setting aligns better with the body’s natural cooling process before sleep, promoting improved sleep quality and potential savings on energy bills.
- Most Americans prefer sleeping at around 67°F, not 78°F
- Cooler temps help the body’s core temperature drop for better rest
- Adjustable fans and smart thermostats can enhance sleep comfort
What happened
A comprehensive American Sleep Habits Study surveyed 2,119 adults across all 50 states to understand their preferred bedroom temperature for better sleep. The widely accepted 78°F benchmark was challenged, with the majority indicating a preference for cooler temperatures, averaging 67°F nationally. Variations occurred by region, such as Massachusetts at 63.2°F and Hawaii at 69.5°F, reflecting local climate influences.
Experts collaborating with the study emphasized how cooler bedroom temperatures support the natural physiological drop in core body temperature before and throughout sleep. This finding marks a significant shift from previous assumptions and highlights the importance of creating a sleep environment that aids this cooling process.
Why it feels good
Temperature regulation is a key component of achieving restful sleep. As the body prepares to sleep, it naturally cools down, a process that is easier in a room set to around 67°F. This supports quicker sleep onset and decreases awakenings during the night, leading to more restorative rest. Being too warm, such as at 78°F, can interfere with this process, especially when combined with heat-retentive bedding or humid conditions.
During REM sleep, a stage crucial for memory and mood regulation, the body’s ability to adjust temperature lessens, making a cooler sleeping environment even more critical. This balance allows for deeper sleep cycles and a less disruptive night’s rest.
What to enjoy or watch next
To maintain an ideal sleep environment at home, consider incorporating cooling sleep essentials such as breathable muslin bedding, silk pillowcases that help regulate temperature, and versatile room fans with adjustable speeds and oscillation features. These items work together to optimize air circulation and comfort throughout the night.
Smart thermostats provide added convenience by allowing precise, programmable control of bedroom temperature, enhancing sleep comfort while also reducing energy use. As preferences vary, starting in the 65-68°F range is recommended, with adjustments made according to personal comfort, bedding choice, and humidity levels.
