‘True master’ Japan man sleeps 30 minutes a day for 12 years to ‘double’ life
Entrepreneur says he has trained his mind and body so he never feels tired, swears by coffee and sports to stay alert

A man in Japan has slept only 30 minutes each day for 12 years in a bid to “double” his life, claiming it has improved his work efficiency.
Daisuke Hori, 40, from Hyogo prefecture in western Japan, said he has trained his brain and body to function normally with minimal sleep and never feels tired.
Hori is an entrepreneur, who loves music, painting and mechanical design.
He started cutting back on sleep 12 years ago to gain more active hours each day and managed to reduce his sleep to only 30 to 45 minutes a day.
“As long as you do sports or drink coffee an hour before eating, you can stave off drowsiness,” he said.

In 2016, Hori founded the Japan Short Sleepers Training Association, where he conducts classes on sleep and health.
