In this short monologue, Dr. David Perlmutter introduces the concept of a “sleep divorce,” which means partners sleeping in separate beds or rooms. He explains that sharing a bed can lead to frequent nighttime disturbances such as movement, snoring, or other interruptions that reduce restorative sleep. Dr. Perlmutter emphasizes that adequate, uninterrupted sleep is crucial for brain health and overall cognitive function. He suggests that creating a dedicated sleep environment—by sleeping apart—may improve sleep quality and thereby support the brain’s long‑term health, without implying any relationship problems.

A sleep divorce might actually be what your relationship needs. Hey, I'm Dr. David Perlmutter. First, what is a sleep divorce? A sleep divorce means actually sleeping in separate beds. That might be a good thing for you. I'm not trying to make any insinuation here about your relationship, but in terms of getting a better night's sleep, it could be that your partner is keeping you from sleeping adequately, getting not enough restorative sleep. By virtue of the fact that he or she may be awakening you during the middle of the night by movement, by snoring, by who knows what. So the idea of sleeping in a dedicated room, a dedicated area where you can control more so the environment, might be a good thing because sleep is so incredibly important for your brain's destiny, for your brain health. So think about it.
