Scientists Identify New Mutation That Enables Three-Hour Sleepers
Researchers have pinpointed a mutation in the SIK3 gene that allows certain individuals to thrive on a mere three to six hours of sleep. Published in PNAS, this exciting discovery contributes to the expanding list of genetic variants associated with naturally short sleepers. By testing the mutation in mice, scientists found they needed 31 minutes less sleep each day, with implications for our understanding of sleep’s biological roles.
Aside from enhancing our grasp of sleep regulation, these findings could pave the way for innovative treatments for sleep disorders.
Key Points
- The genetic mutation in the SIK3 gene aids some individuals in functioning on only three to six hours of sleep.
- Mice with the mutation showed a daily sleep reduction of 31 minutes.
- The research adds to knowledge of genetic factors linked to short sleep duration.
- Enhanced sleep regulation understanding may lead to new treatments for sleep disorders.
- This is the fifth mutation identified across four genes affecting naturally short sleepers.
