Short sleeper syndrome (SSS) is a sleep condition characterized by sleeping for fewer than six hours each night. Most adults need seven or more hours of sleep each night to feel rested in the morning. Those with SSS, however, can function normally throughout the day despite less sleep. They don’t need to take naps or sleep more than normal to recover from lack of sleep. These individuals are different from those short sleepers who choose to limit their sleep.⁠ ⁠ Minimal sleep requirement occurs naturally for people with SSS. They don’t purposefully restrict or avoid sleep. In fact, their short sleep pattern remains consistent on most nights, including weekends and holidays.⁠ ⁠ The pattern of short sleep usually begins in childhood or adolescence and continues into adulthood. Researchers believe it may develop due to a gene mutation. This mutation may be what enables people to function well on fewer than six hours of sleep each night.⁠ ⁠ ⁠ ⁠ ⁠ #shortsleep #sleep #sleeping #biology #dna ...
