Can you survive on 1 hour of sleep a night?

No, you cannot survive long-term on just one hour of sleep; it's extremely unhealthy and unsustainable, leading to severe cognitive impairment, weakened immunity, and increased risk of chronic diseases like heart disease, stroke, and diabetes, though very rare genetic variations allow for short sleep, and a few days of very little sleep might be manageable, consistent deprivation is dangerous.
