The bizarre reason some people are fine on just four hours of sleep a night

• Scientists identified a rare gene mutation (N783Y in the SIK3 gene) that allows some individuals to function well on only 4-6 hours of Sleep.
• This mutation affects a phosphate exchange process crucial to the Sleep-wake cycle, leading to less Sleep and potentially more deep Sleep.
• Mice with the same mutation slept 30 minutes less than unaltered mice, confirming the gene's role in Sleep duration.
• This discovery could lead to new therapies for Sleep disorders and improve Sleep quality.
• The mutation seems to increase deep Sleep in those who have it.
