- In ancient Rome the marital bed was meant for a couple's sexual relationship, not for sleeping reports BBC News. One study found that the average couple had 50 % more sleep disturbances if they shared a bed.
- The University of Surrey professor said that sleeping apart could prevent couples from getting poor sleep that leads to depression, heart disease, strokes, lung disorders, traffic and industrial accidents, and divorce reports the Nerdy Science Blog. As reported by BBC News, Dr Stanley, who sleeps separately from his wife, was responsible for setting up one of Britain's leading sleep laboratories at the University of Surrey. He said that people of today should consider doing the same. He says, “We all know what it’s like to have a cuddle and then say ‘I’m going to sleep now’ and go to the opposite side of the bed. So why not just toddle off down the landing.”
- A 2005 National Sleep Foundation survey found that 31% of couples are changing their sleep habits because of a mate's sleep problems reports WebMD. The survey found that 23% sleep in separate beds and that 38% said that their partner's sleep disorder has caused problems in their relationship. Louanne Cole Weston, PhD, a sex therapist and author of WebMD's Sex Matters message board says sleeping apart can be good for a relationship and "It does not signal the end of a relationship at all. In fact, it can be the beginning. If one person has been sleep-deprived, they begin to feel more interested in sex. If you've ever slept next to a person who snores, you have to cope with waking up several times during the night. It does not create good will in a relationship."
