A MAN claims he has been getting only 30 minutes of sleep every night for the past 12 years.

       Daisuke Hori, 36, says he has trained his mind and body to function on as little sleep as possible - and boasts he never feels tired.

       He allowed a TV crew into his home to document his sleeping schedule

       The 36-year-old, from Japan, claims he does not have any side effects from sleep deprivation and is now teaching others how to do the same.

       Daisuke, chairman of the "Japan Short-sleeper Association", was featured on a TV show to discuss his bizarre sleeping schedule.

       He said he always felt that 16 hours was not enough time for all the things he wanted to do during the day so he started researching and experimenting.

       He claims he was eventually able to lower his sleeping time from eight hours to 30 minutes while being still "healthy and energetic," Oddity Central reports.

       When the TV show producers challenged him to prove his sleeping routine he allowed a TV crew into his house for three days to document him.

       And he somehow got 30 minutes of sleep and some nights even less.

       On the first day Daisuke woke up at 8am and spent his day working, going to the gym, reading, playing video games and socialising before heading to bed at 2am.

       After a mere 26 minutes of sleep, he woke up and went on a late-night surf with other short sleepers.

       And while some viewers questioned how he was not getting sleepy after a meal, Daisuke explained that he did get sleepy but stayed awake with caffeinated drinks.

       MYSTERY CONDITION

       It follows another case in China as a woman with a mystery condition that has baffled doctors claims she has not had a night of shut-eye for the past 40 years.

       Li Zhanying, from the eastern Chinese province of Henan, claims she has not slept since she was five years old- something that her husband confirmed.

       She even sought medical help for her condition but doctors were unable to provide a diagnosis.

       Eventually a medical team concluded that she had a condition similar to sleepwalking, in that her body was still active while she was asleep.

       This meant that she was getting a little bit of sleep while still being able to maintain a conversation with her husband.

       The NHS suggests you should get between six and nine hours of sleep a night and advises you to keep a bedtime routine and try and wake up at the same time every day.
