Sometimes you just need human contact, and cuddling is a great way to get that fill.  Other than giving you butterflies in your stomach, cuddling helps you warm up, get in the mood, and get rid of the lonely blues.  To add to the list of why everyone needs a cuddle buddy while sleeping, science has found some serious health benefits to snuggling with a partner. 

A new study published in The Wall Street Journal found that there are psychological benefits to sharing a bed with someone every night. 

If you're very stressed from work or life, then the answer might just be finding a snuggle buddy!  Cuddling makes people feel safe and secure, it lowers levels of cortisol or stress and reduces cytokines, which contributes to inflammation, and raises your level of oxytocin. 

"Sleep is a critically important health behavior that we know is associated with heart disease and psychiatric well-being," Wendy M. Troxel, an assistant professor of psychiatry and psychology at the University of Pittsburgh tells The Wall Street Journal. " It happens to be this health behavior that we do in couples." 

You might still not be the type to jump at the chance to sleeping throughout night with your man.  After all, things like snoring, kicking, and someone talking in their sleep tends to make many couples sleep separately in order to get a good night's rest.  However, Troxel says couples that opt out of cuddling are doing themselves a disservice. 

"The psychological benefits we get having closeness at night trump the objective costs of sleeping with a partner," says Dr. Troxel.
