Cine sunt oamenii care dorm doar 4-5 ore pe noapte și nu simt oboseala: misterele geneticii somnului scurt natural

Some individuals, like Brad Johnson, naturally require only 4-5 hours of sleep without feeling tired, due to rare genetic mutations. Research identifies families with these traits linked to specific genes, such as ADRB1 and DEC2. Unlike most people, who may suffer from sleep deprivation, these individuals wake refreshed after short sleep durations. Scientists are exploring how their brains manage sleep needs and restoration processes, revealing that sleep is crucial for various bodily functions. Despite the allure of needing less sleep for productivity, many people underestimate their actual sleep requirements, often masking fatigue with caffeine. Understanding the genetics of short sleepers may unlock mysteries of sleep regulation and health.
