Scientists Explore Secrets of Natural Short Sleepers
Some people are born with a special ability to feel well-rested after only a few hours of sleep.
These people are called natural short sleepers, and they have a unique genetic makeup that allows them to get the benefits of sleep in a shorter amount of time.
Scientists are studying these individuals to understand how sleep works and to find new ways to help people with sleep problems, like insomnia.
This research could lead to new treatments that help people sleep better, even if they can't get a full night's rest.
Natural short sleepers function optimally on 3-5 hours of sleep per night.
This trait, called FNSS, is genetically driven and often runs in families.
Researchers have identified several gene mutations linked to short sleep.
Understanding FNSS could lead to new treatments for sleep disorders.
Unlike natural short sleepers, most people require 7-8 hours of sleep.
- Who
- Scientists studying individuals with Familial Natural Short Sleep (FNSS).

- When
- Ongoing research, with key findings since 2009.
- Where
- Primarily at research institutions like the University of California, San Francisco.
- Why
- To understand the genetics of sleep and potentially develop treatments for sleep disorders.
