In Japan, a man has adopted an extreme sleep regimen in an attempt to “double” his life, claiming significant benefits from his ultra-short sleep schedule.
Daisuke Hori, 40, from Hyogo Prefecture in western Japan, has been limiting his sleep to just 30 minutes a day for the past 12 years, believing this has improved his work efficiency.
He has trained himself to function normally on minimal sleep and feels consistently energized. As an entrepreneur with interests in music, painting, and mechanical design, he cut his sleep to 30 to 45 minutes daily to extend his active hours.
Hori suggests that engaging in sports or drinking coffee an hour before meals can help combat drowsiness. In 2016, he founded the Japan Short Sleepers Training Association to educate others about sleep and health.
In the reality show “Will You Go With Me?” Hori demonstrated his routine, including a 26-minute sleep on the first day, followed by a full day of activities. His online resume states that he has trained over 2,100 students to adopt ultra-short sleep patterns, with one student reducing her sleep from eight hours to just 90 minutes daily while maintaining good skin and mental health.
This unconventional approach has sparked intense debate on social media, although doctors caution against ultra-short sleep, emphasizing that adults need seven to nine hours of sleep each night for proper recovery.
Chronic sleep deprivation can lead to memory issues, weakened immunity, mood disorders, and increased cardiovascular risks.
