It depends on the person. Need for sleep follows a normal distribution in terms of what you require. Natural short sleepers who only need 4.5 hours exist. Most people who sleep that much are chronically sleep deprived but there are people who just genuinely don't need that much sleep. https://www.nlm.nih.gov/medlineplus/ency/article/000804.htm I'm not a short sleeper but I need closer to seven hours sleep a night than eight. |
