A guy from Japan has been sleeping for 30 minutes a day for 12 years.
The guy sleeps for half an hour a day to double his lifespan. He has maintained this schedule for 12 years. He claims that his work has become more efficient. The 30-year-old from Japan told xrust that his brain is trained to function normally while getting minimal sleep. His body never feels tired. This guy is engaged in entrepreneurship and loves music and painting. He started reducing his sleep time 12 years ago to increase his active hours. Now he has cut his sleep down to 30-45 minutes a day. He told reporters that he exercises or drinks coffee an hour before sleeping. This trick helps to alleviate drowsiness. In 2016, he founded the Japanese Association of Short Sleep. There, he conducts classes on sleep and health. His idea is that concentration increases with quality sleep, which cannot be achieved merely through duration. A typical example is doctors and firefighters. These professions have short sleep, but their work is productive. Japanese television crews followed his routine for three days. He really wakes up full of energy after a 26-minute nap.
