What happens to the human body when you completely strip away sunlight, clocks, and human contact? In this fascinating science documentary, evolutionary biologist Ella Al Shamahi teams up with sleep and circadian experts to test the absolute limits of our internal body clock.
Following former Royal Marine commando Aldo Kane as he spends 10 days isolated inside a dark, underground nuclear bunker, we uncover the hidden molecular machinery that controls our sleep, mood, and long-term health. From the genetics behind "early birds" and "night owls" to the dangerous realities of shift work and social jet lag, discover how you can take back control of your biology and hack your body clock for a healthier, happier life.
