Why sharing a bed is good for the heart

Snoring, sweating, stealing the sheets . . . it’s little wonder that an estimated one in four couples insist on sleeping in separate rooms.

Now, however, there’s an emerging body of research to suggest there could be health benefits to sharing a bed with a long-term partner.

It’s even been suggested as a major reason why people in close relationships tend to be in better health and live longer.

Researchers from the University of Pittsburgh in the U.S. believe sleeping next to someone helps lower the stress hormone cortisol, perhaps because it encourages feelings of safety and security.

Prolonged periods of elevated cortisol have been linked with an increase in cytokines — proteins involved in inflammation that can trigger heart disease, depression and auto-immune disorders.

Sleeping together has a protective effect by lowering the levels of these proteins.
