The optimal sleeping temperature for most adults is generally between 60°F and 67°F (15.5°C to 19.4°C). This range helps facilitate the body's natural drop in core temperature, which is essential for achieving restful sleep.
Finding the right sleeping temperature is crucial for achieving quality sleep. Research indicates that the ideal room temperature for sleep typically falls between 60°F and 67°F (15.5°C to 19.4°C) for adults. This range is optimal because it aligns with the body's natural circadian rhythms, which involve a decrease in core body temperature during sleep. A cooler environment can help facilitate this process, promoting deeper and more restorative sleep stages, particularly REM sleep, which is vital for cognitive function and overall health [1][2][4].
While adults benefit from cooler temperatures, infants may require slightly warmer conditions, although it is important to avoid overheating them. Recommendations suggest keeping their sleeping environment at a temperature that is only a few degrees higher than the adult range [1].
Some sources suggest a slightly broader range, indicating that temperatures between 60°F and 68°F (15.5°C to 20°C) can also be effective, depending on individual preferences and bedding choices [3][5]. However, exceeding this range can lead to discomfort and disrupted sleep, as being too hot can prevent the body from entering deeper sleep stages [2][4].
In summary, while individual preferences may vary, maintaining a room temperature within the 60°F to 67°F range is generally recommended for optimal sleep quality. Adjustments may be necessary based on personal comfort, bedding, and seasonal changes.
