The least amount of sleep an individual can function on varies widely, but most adults typically need between 7 to 9 hours for optimal health and performance. Some people may manage with as little as 4 to 5 hours occasionally, but chronic sleep deprivation can lead to serious health issues, including impaired cognitive function and weakened immune response. It’s important to note that individual sleep needs can differ, and consistently getting less sleep than needed can have detrimental effects.
