Scientists have identified a gene mutation, SIK3-N783Y, responsible for allowing some individuals to thrive on significantly less sleep. Studies in mice carrying this mutation showed reduced sleep time, confirming its role. Researchers hope this discovery will lead to better treatments for sleep disorders. While most adults need 7-9 hours of sleep, natural short sleepers function well on 4-6 hours, experiencing negative effects with more. This mutation affects the Sik3 gene, previously linked to sleepiness, offering a potential therapeutic target for improving sleep.
