Bryan Johnson has warned that “poor sleep” makes people uglier, adding to his series of health obsessions. The controversial biohacker, 48, has built a large following on his mission to cheat death, documenting everything from bodily functions to bedroom habits in his quest for longevity.
Sleep and attractiveness
Writing on X, Johnson said: “Sleep makes you look better. Poor sleep makes you less attractive. The science on this is robust.” In response, one user joked: “Eating makes you less hungry. Not eating makes you more hungry. The science on this is robust.”
Johnson’s dedication to sleep is well known. Every day, the tech entrepreneur tries to be asleep by 8.30pm, sleeping alone until 5am, when he wakes to resume his formalised routine focused on slowing ageing.
Sleeping arrangements and girlfriend's regimen
Recently, Johnson asked followers whether he should sleep in the same bed as his girlfriend, Kate Tolo. Currently, Tolo sleeps in a different part of the house to avoid interfering with his sleep scores. Kate, 30, is reportedly undergoing a 100-day regimen that monitors her menstrual cycle in extreme detail, accumulating a claimed 14 million data points. Her routine allegedly includes spitting into collection tubes, cheek swabbing, sleeping with an acrylic vaginal tracker, and using a “techno-tampon” designed to extract deeper data.
Johnson asserts the tracking has revealed diagnoses for Tolo, including polyendocrine metabolic ovarian syndrome and adenomyosis, conditions associated with chronic, severe period pain. He contends menstrual blood provides a direct “uterine blueprint”, containing endometrial tissue, immune cells and stem cells. He suggests freezing a 10mL sample could help investigate the uterine environment without invasive surgical biopsies.
Previous claims about partner
The billionaire previously declared his partner has a “top 1%” vagina after performing oral sex on her and posting results online. He said Tolo’s sample was “dominated by the single most protective bacterial species a vagina can host”, as reported by the Daily Star.
