How many hours of sleep per night does the average person need to avoid accumulating sleep debt?

The average person typically requires between 7 to 8 hours of sleep per night to function optimally and avoid accumulating sleep debt. This amount of sleep is generally recommended by health professionals and organizations, such as the National Sleep Foundation, as it is associated with improved cognitive function, emotional well-being, and overall health.

Getting less than this recommended amount can lead to a shortfall in sleep which, over time, results in sleep debt. Even if someone feels they can function on less, chronic sleep deprivation can lead to negative health effects, including issues with memory, mood, and immune function. Therefore, aiming for 7 to 8 hours is essential for maintaining good health and mitigating the risks associated with insufficient sleep.
