Most of us are aware that healthy adults require between 7-9 hours sleep for optimum cognitive and physical health. However, Daisuki Hori, a Japanese entrepreneur, claims to have slept for 30-45 minutes a night for the past 12 years.
Why? In a bid to boost his overall productivity. With more hours in a day, this reckless sleep hack is the secret to his success, he claims. However, sleeping for just 30-45 minutes per night flies in the face of expert advice and sleep studies, which link poor sleep to poor cognitive function and physical health.
For Hori, his claims that being an 'ultra short sleeper' has been so successful that he's now on a quest to teach others to do the same. But is it safe? To find out if it's ever possible to survive (and thrive) on such minimal sleep and to explore the long term health consequences of severe sleep deprivation, we speak to a doctor of sleep medicine and certified sleep coach.
