No, consistently sleeping only 5 hours a night is generally not considered enough for most adults. Experts recommend at least 7 hours of sleep per night for optimal health. While some individuals might function adequately on less sleep, getting fewer than 7 hours regularly can negatively impact both physical and mental well-being. A large body of research links consistently short sleep durations to increased risks of various chronic health problems.

Individual Variations
It's important to note that individual sleep needs vary. Some people might naturally require less sleep than others. However, the majority of adults benefit from 7-9 hours of sleep nightly. Five hours of sleep might be sufficient for a small minority, but for most, it falls significantly short of what's needed for optimal health. If you are consistently only sleeping 5 hours, consider consulting a doctor to rule out any underlying sleep disorders and discuss strategies to improve your sleep.
