Washington, Feb 10 (ANI): Strong partnerships can help us avoid illness, adopt healthier habits, and even live longer, while on the other hand, troubled relationships tend to breed stress and weaken immunity, a study has found.
"So many factors affect our health, whether it's the behaviors we exhibit toward each other or the habits that we pass on to each other," Foc News quoted psychologist Maryann Troiani, co-author of Spontaneous Optimism as saying.
So whether you're dating casually, shacking up, or already married, keep in mind the key ways your romantic bond may influence your mind and body.
Try watching your weight, as it's a common belief that couples "let themselves go" after pairing off, and there may be something to it.
According to a 2012 review, people tend to gain weight as they settle into marriage and lose weight when a marriage ends.
"A happy couple can motivate each other to stay healthy-they'll go to the gym together, set goals, and feel responsible for each other," Troiani said.
When couples do pack on the pounds, she adds, it may be a symptom of conflict, not slacking off.
Regular physical intimacy appears to reduce stress and boost well-being.
One study, published in 2009 in the Journal of Sexual Medicine, found that people who frequently had sex were healthier mentally and more likely to report greater satisfaction with their relationship and life overall.
Parenting disputes, disagreements over money, or even questions as simple as who does which household chores have been shown to increase stress.
Sex isn't the only type of physical contact that can lower stress and improve health.
In a 2004 study of 38 couples, University of North Carolina researchers found that both men and women had higher blood levels of oxytocin-a hormone believed to ease stress and improve mood-after hugging.
Sleeping next to someone you love and trust can help you fully relax and embrace sleep, Troiani said.
A big exception to that rule, of course, is if your bedmate keeps you up at night-by snoring, for instance, or by tossing and turning.
Relationships can affect sleep in less direct ways, too. Research shows that relationship insecurity or conflict is associated with poorer sleep-and to make matters worse, sleep problems can exacerbate relationship problems, creating a vicious cycle.
Relationship difficulties can put anyone on edge, but in some cases they may actually contribute to full-blown anxiety.
Several studies have found a link between marital problems and an increased risk of diagnoses such as generalized anxiety disorder and social anxiety.
Depression and anxiety often go hand in hand, so it makes sense that relationships can affect depression in similarly complex ways.
On the one hand, some studies have found that long-term relationships-and marriage, specifically-can ease symptoms in people with a history of depression.
On the other hand, fraught relationships have been shown to dramatically increase the risk of clinical depression. In one small but highly cited study, women-regardless of their personal and family history of depression-were six times more likely to be clinically depressed if their husbands had been unfaithful or if their marriages were breaking apart.
Finally, restrict your Alcohol intake. Our romantic partners have a noticeable impact on how much alcohol we consume, and how often.
One study, which followed more than 600 couples during their first four years of marriage, found that people's drinking habits tended to mirror those of their spouse; if their partner drank heavily, they too were more likely to do so.
It's also true that relationship conflict and a lack of intimacy can drive people to drink.
Research suggests that both men and women drink more in response to relationship problems-and excessive drinking, in turn, can add fuel to those problems. (ANI)
