Yes, you heard that right,” Johnson said, clarifying that he and Kate have separate beds and separate homes.Johnson cited studies that have produced mixed findings on whether sharing a bed with a partner is better for sleep.He referred to a study of 55 couples that found around six partner-triggered awakenings per night. However, he noted that science is divided. Citing a separate study involving 12 couples, Johnson said sleeping together was associated with about 10% more Rapid Eye Movement sleep and greater synchronisation of sleep stages between partners. He also pointed to differences between men and women in how sharing a bed may affect sleep. One study found that women slept measurably worse when sharing a bed with a partner, while men reported sleeping better.At the same time, he cited a survey of 1,000 adult couples who slept together and reported better overall sleep, less insomnia, less fatigue and better mental health. However, Johnson highlighted the limitation that the findings were self-reported. This means happier and healthier people may simply be more likely to share beds. So, should couples sleep alone or together? Johnson said it depends on the couple. For some, sharing a bed may improve sleep, while for others, separate beds could help protect their sleep - and possibly their relationship.Bryan Johnson, who is known for his highly regimented approach to health and longevity, frequently shares details of his lifestyle and health experiments.- EndsPublished On: Aug 17, 2026 16:06 IST
