American millionaire and biohacker Bryan Johnson, who continues his fight against aging, has revealed why he has not slept with his girlfriend Kate Tolo for almost four years. This was reported by Qazaqyia.kz citing Kursiv Media.
According to the New York Post, Johnson and Tolo sleep separately and even live in different houses. The biohacker says this arrangement allows them not to disturb each other during sleep.
He believes that sleeping next to a partner can cause more frequent interruptions due to the movements and awakenings of the other person. Poor sleep, in Johnson's view, can accelerate biological aging. As evidence, he cited a 2020 study involving 55 couples. According to its data, partners could wake up about six times a night because of each other.
However, Johnson acknowledges that scientific data on co-sleeping is mixed. Another study with couples showed that sleeping in the same bed, on the contrary, can synchronize partners' sleep phases. The seasoned biohacker himself prefers not to share his bed with anyone.
This format is called "sleep divorce." It does not necessarily indicate relationship problems. Couples may sleep in separate rooms due to different schedules, snoring, restless sleep, or simply a desire to sleep better.
According to the biohacker, there is no universal rule.
"For some couples, co-sleeping improves sleep. For others, separate beds can save sleep or relationships. Perhaps both," Johnson said.
Meanwhile, a survey by the American Academy of Sleep Medicine found that 35% of Americans sometimes sleep separately from their partner.
Recall that in July, Johnson reported that he had been diagnosed with autoimmune gastritis. The disease had been asymptomatic for a long time, with the only sign being a consistently low iron level in the blood.
