Da Vinci’s Sleep Pattern

Author: galeweathershistory

Leonardo da Vinci is famously associated with a polyphasic sleep schedule known as the Uberman cycle, which allegedly involved sleeping for 15–20 minutes every four hours, totaling only 1.5 to 2 hours of sleep per day. This method was designed to maximize productive waking hours by distributing sleep into multiple short naps throughout the day.

However, historical evidence for da Vinci actually following this routine is limited and likely mythical, with no direct references in his surviving notebooks; the claim was likely retroactively applied to his legacy in the 20th century. Modern sleep science considers this schedule incompatible with human circadian rhythms, noting that it prevents the brain from completing essential sleep stages like REM and deep sleep, which can lead to cognitive impairment and health issues. While some historical figures like Nikola Tesla and Thomas Edison also reportedly slept very little, experts warn that such extreme sleep reduction is generally unsustainable for the average person, even resulting to insanity in some individuals.

Fascinating.

“The disorder primarily affects totally blind individuals, with 50–70% of this population affected, due to the lack of light perception needed to reset the circadian clock. It is rarer in sighted people and may stem from neurological conditions, head trauma, or insensitivity to light.” HAHA GO FIGURE MEOW WAS DROPPED ON HER HEAD AS A BABY

The sex obsessed masses are actually insane. The entitlement that people have towards another persons body is one of the main reasons I consider it a legit hazard to date. They don’t care if the other person is tired, not in the mood, has to wake up early, in pain, anxious or simply does not want to. It’s all ME ME ME ME, my lust, my needs. You can go out on a date and all they’re thinking is “Will I get to fuck after this? Have I done enough?”. What happened to enjoying someone else’s company, conversational skills and empathy for another human being? The most lascivious, salacious and licentious people are currently walking amongst us and masking. That is terrifying. Using people for their own personal pleasure and then discarding them if they don’t ‘put out’ enough times a week. And they’ll say this with a straight face like they’re not sick. But WE are the weird ones? Tell us you have zero self awareness without telling us.

I can’t stand when people question why I’m single because it shows how totally oblivious they are to the current state of the dating scene. It’s practically sex work at this point with extra steps. The unspoken consensus is “I pay for the date, you give me access to your body eventually”. NO THANKS. And why the fuck do women not realise this?! It’s literally self harm…
