Man claims he only sleeps for 30 minutes every day to ‘double’ his life

Daisuke Hori claims he's trained himself to only need 30-45 minutes of sleep per day to function normally and believes it's helping him 'double' his life.

A 40-year-old man from Japan called Daisuke Hori alleges he's been getting under an hour of sleep per day for the last 12 years.

It should go without saying but I'll say it anyway, you definitely shouldn't try this at home.

Starting Japan Short Sleepers Training Association in 2016, Hori claimed the key to focus and energy is having more high-quality sleep opposed to longer durations of sleep, arguing his method will help him 'double' his life, South China Morning Post reports.

Hori appeared on reality TV show Will you go with me?, the crew tracking his activity for several days and indeed showing him only sleeping for a reported 26 minutes per day, his daily routine seeing him wake up at 3am and go to sleep at 2:30am.

He said: "As long as you do sports or drink coffee an hour before eating, you can stave off drowsiness."

Look, we all feel like there aren't enough hours in a day to get things done sometimes but that certainly doesn't mean you should start cutting your sleep down to under an hour anytime soon, with a lack of sleep coming with some serious potential consequences to your health.

Sleep medicine specialist Nancy Foldvary-Schaefer, DO, MS tells Cleveland Clinic getting enough sleep is crucial for 'cardiovascular health, metabolic health and even brain health' as it helps to 'restore nutrients, clear toxic materials and recharge for the next day'.

And should you not get enough sleep? Well, even if you get 1.5 hours less than you normally do, you could end up suffering from fatigure, grogginess, heightened anxiety, forgetfulness, poor balance and coordination, eye bags, a weaker immune system and an increased risk of health issues such as cardiovascular disease and dementia.

And despite what Hori argues, Dr Foldvary-Schaefer said: "During periods of sleeplessness, hidden health hazards accumulate that can’t be covered up with concealer or reversed with caffeine.

"Everything from your cardiovascular system to your immune system feels the impact."

But how much sleep do you actually need?

Well, the National Sleep Foundation advises those aged between 14 to 17 to get eight to 10 hours, those aged between 18 to 25 to get between seven to nine hours and if you're 26 to 64, you should be getting from seven to nine too.

Dr Foldvarey-Schaefer resolves: "Adults need seven to eight hours of sleep each night — not just once in a while. If you’re not getting that, you’re likely chronically sleep deprived. It’s the most common cause of tiredness in our society today."
