What is the recommended sleep duration range for most adults to support optimal health?
Answer
Seven and nine hours per night
For the vast majority of adults seeking optimal health and cognitive function, experts advise securing a minimum of seven hours up to nine hours of sleep nightly. This established duration is crucial because it allows the body sufficient time to complete necessary restorative processes, which include physical restoration and the consolidation of memories. Falling consistently below this established baseline requirement leads to the accumulation of sleep debt, which negatively affects alertness, overall mood stability, and long-term wellness. Therefore, this specific seven-to-nine-hour range serves as the essential quantitative starting point for determining a healthy bedtime.
