According to The Wall Street Journal, in their June article, "Who Sleeps Better At Night", sleep experts suggest new ways to deal with couple - sleep problems - without resorting to separate bedrooms. Researcher Wendy M. Troxel, an assistant professor of Psychiatry and psychology at the University of Pittsburgh says, "Sleep is a critically important health behavior that we know is associated with heart disease and psychiatric well-being," In Toxel's 2009 published study, she found that women in long-term stable relationships fell asleep more quickly and woke up less during the night than single women or women who lost or gained a partner during the six to eight years of the study.
Troxel also found that sleeping in the same bed promotes feelings of safety and security, shared sleep in healthy relationships may lower levels of cortisol, a stress hormone. Sharing a bed may also reduce cytokines, involved in inflammation, and boost oxytocin, the so-called love hormone that is known to ease anxiety and is produced in the same part of the brain responsible for the sleep-wake cycle.
There are so many reasons why couples have trouble sleeping in the same bed. A different body clock, body temperature, stress, an argument, snoring, or even a parent who kicks the other one out because of co-sleeping. Clearing up a relationship issue can sometimes ease insomnia, says Christina S. McCrae, associate professor at the University of Florida and president of the Society of Behavioral Sleep Medicine. She has had several patients whose sleep improved after underlying relationship problems were addressed with their spouses during sleep-therapy sessions.
