Sleeping for eight hours is generally considered ideal for adults, with experts saying that consistently getting this much sleep can improve cognitive function, mood, and overall health. However, a man in Japan has been sleeping only for 30 minutes a day for the past 12 years. Daisuke Hori, 40, claimed he had trained his brain and body for minimal sleep to "double" his life. According to the South China Morning Post, Hori, who hails from Hyogo prefecture in western Japan, has managed to reduce his sleep to only 30-45 minutes a day and claimed that it has improved his “work efficiency”. Hori, an entrepreneur, also claimed that high-quality sleep is more important than long sleep for maintaining focus at work. “As long as you do sports or drink coffee an hour before eating, you can stave off drowsiness. People who need sustained focus in their work benefit more from high-quality sleep than long sleep. For instance, doctors and firefighters have shorter rest periods but maintain high efficiency," Hori told the Hong Kong newspaper. To look closer at Hori’s claims, Japan’s Yomiuri TV studied him for three days in a reality show titled Will You Go With Me? According to the show, Hori once slept for just 26 minutes and woke up with enthusiasm, headed to work after breakfast, and hit the gym. In 2016, Hori embarked on a new journey and founded the Japan Short Sleepers Training Association. One of the participants claimed that she cut her sleep from eight hours to only 90 minutes after the training and followed it for four years. She also claimed to have managed to take care of her skin and mental health. The South China Morning Post also reported that Hori, who loves music, mechanical design, and paintings, had trained over 2,000 students to become ultra-short sleepers.
