Daisuke Hori, a 40-year-old entrepreneur from Japan, has reportedly slept only 30 minutes a day for the past 12 years, claiming it has “doubled” his life and improved his work efficiency. Hori trained his body to function on minimal sleep and believes high-quality sleep is more beneficial than long sleep. He founded the Japan Short Sleepers Training Association in 2016 to teach others his methods. His extreme sleep schedule was featured in a reality show, and he cites practices like exercise and coffee to combat drowsiness.
