The Man Who Lived Without Time – Michel Siffre’s Cave Experiment

Описание: What happens when you live with no clocks, no sun, and no sense of time?

In 1972, French scientist Michel Siffre descended into total isolation inside a cave in Texas—no daylight, no schedule, no contact with the outside world. What he discovered reshaped our understanding of the human biological clock.

In this video, we dive into Siffre’s bizarre 48-hour sleep cycle, how it challenged science, and what it reveals about your circadian rhythm today. From the brain’s internal clock to practical tips on resetting your sleep schedule, this experiment holds powerful lessons for modern life.

⏰ Can your body really tell time without light?
