Key Takeaways
- The ideal sleep temperature identified by a recent Bear Mattress study is 67 °F, far cooler than the 78 °F commonly recommended for energy savings.
- State‑level preferences vary widely, with Massachusetts residents favoring the coolest average (63.2 °F) and Hawaiians the warmest (69.5 °F).
- Over 2,000 adults from all 50 states participated, mapping sleep comfort to geography and generation.
- Only a minority of thermostat users set temperatures above 76 °F in summer, indicating a general preference for cooler indoor settings.
- Regional climate, gender, age, and sleeping habits significantly shape how Americans define “comfortable” temperature.
Ideal Sleep Temperature Survey Overview
Sleep wellness brand Bear Mattress released findings from a nationwide sleep study on July 8, 2026, that surveyed more than 2,000 adults across all 50 states. Respondents reported their preferred bedroom temperature, bedtime routines, and habits while answering questions about comfort, temperature, and regional influences. The research linked these metrics to geography and generational patterns, aiming to illustrate how environmental and cultural factors intertwine to affect sleep quality. The methodology combined quantitative temperature data with behavioral observations, providing a comprehensive snapshot of American sleep preferences in 2026.
National Average Preferred Temperature
The study pinpointed 67 °F as the “ideal sleep temperature” for the United States as a whole. This figure represents the temperature most Americans reported as optimal for both falling asleep quickly and maintaining uninterrupted sleep throughout the night. While 67 °F serves as a national benchmark, the data reveal considerable variation when examined at the state level, underscoring the importance of local climate considerations in personal temperature preferences.
Regional Differences in Sleep Temperature Preferences
Massachusetts emerged as the coolest‑preferring state, with an average sleep temperature of 63.2 °F, while Hawaii recorded the warmest preference at 69.5 °F. The findings suggest that regional climate plays a pivotal role in defining what residents perceive as comfortable. For example, individuals in colder northern states may gravitate toward lower thermostat settings, whereas those in tropical locales often report higher ideal temperatures. Such geographic trends reinforce the notion that a one‑size‑fits‑all temperature recommendation may not align with local comfort realities.
Comparison with Daily Thermostat Settings
A 2021 Consumer Reports survey indicated that the average thermostat setting for both day and night across the U.S. hovers around 71 °F. Regional nuances appear here as well: Southern households typically set their thermostats to about 72 °F, while Northeastern users average 70 °F. Notably, fewer than half of respondents with central air conditioning indicated they would ever set a temperature above 76 °F during the summer months, signaling a collective inclination toward cooler indoor environments despite energy‑saving recommendations.
Energy Efficiency Recommendations and the 78°F Guideline
Several utility companies, including Chicago’s Constellation, New York’s National Grid, and Florida’s Carrier, advise setting air‑conditioner thermostats to an average of 78 °F to balance comfort with cost savings. The U.S. Department of Energy underscores that maintaining a moderate indoor temperature helps control humidity and reduces the temperature differential between indoors and outdoors, thereby lowering energy consumption. However, the Bear Mattress data reveal that many Americans find temperatures significantly lower than 78 °F more conducive to restful sleep, suggesting a disconnect between energy‑focused guidance and sleep‑health priorities.
Impact of Regional Climate on Comfort Perception
The study emphasizes that “regional climate plays a major role in how Americans define ‘comfortable.’” Participants from cooler climates often perceive 65 °F as ideal, while those in warmer zones may deem 70 °F acceptable for sleep. This climate‑driven perception influences not only thermostat settings but also sleepwear choices, bedding materials, and bedroom ventilation practices. Understanding these local nuances can guide individuals in tailoring their sleep environments to match personal comfort expectations without compromising overall well‑being.
Sleep Habits and Bedtime Behaviors Across States
Beyond temperature, the research delved into broader sleep habits, finding that 58 % of Americans favor side‑sleeping positions and that, on average, each adult spends roughly three months of the year in bed. States such as Nevada reported the highest sleep quality scores, whereas Oklahoma posted the lowest comfort index among all states. These variations highlight the multidimensional nature of sleep health, wherein temperature is just one component of a broader tapestry that includes sleep position, bedtime routines, and environmental factors.
Demographic and Generational Insights from the Study
The Bear Mattress survey also captured generational patterns, noting that younger adults tended to favor slightly warmer sleep temperatures than older participants, who prioritized cooler environments. Additionally, the data revealed gender differences, with women slightly preferring temperatures about 1 °F cooler than men on average. These subtle distinctions suggest that personalized temperature regulation strategies may need to account for age, gender, and physiological factors to achieve optimal sleep outcomes across diverse populations.
Recommendations for Optimizing Home Temperature Settings
Given the interplay between sleep quality and thermostat settings, experts recommend that individuals experiment with temperatures ranging from 65 °F to 68 °F during summer evenings to determine personal comfort thresholds. Using programmable thermostats or smart home systems can facilitate gradual temperature adjustments before bedtime, ensuring a smooth transition to a cooler sleep environment. Moreover, pairing temperature control with other sleep hygiene practices—such as limiting screen exposure, maintaining consistent bedtimes, and optimizing bedding—can amplify overall sleep efficiency and quality.
Conclusion and Implications
The Bear Mattress study illuminates a clear preference among Americans for cooler bedroom temperatures than those dictated by conventional energy‑saving recommendations. While 78 °F remains a useful guideline for reducing electricity costs, the data underscore that personal health and comfort may warrant setting thermostats to around 67 °F for optimal sleep. Recognizing regional climate influences, generational differences, and individual habits can empower households to fine‑tune their indoor environments, fostering better rest and potentially enhancing overall well‑being.
