Sleep Deficits + Marital Conflict May Hike Risk of Illness

New research finds that lack of sleep does more than leave you cranky and easily irritated with your partner — it may also put you at risk for stress-related inflammation.

Investigators at Ohio State University Institute for Behavioral Medicine Research discovered the inflammation is associated with higher risk of cardiovascular disease, diabetes, arthritis, and other diseases.

Researchers discovered if both partners receive less than seven hours of sleep the previous two nights, the couple was more likely to argue or become hostile.

Moreover, for every hour of sleep lost, the researchers noted that levels of two known inflammatory markers rose six percent. Couples who used unhealthy tactics in their disagreement had an even greater inflammatory response — about a 10 percent increase with each hour of less sleep.

“We know sleep problems are also linked with inflammation and many of the same chronic illnesses. So we were interested to see how sleep related to inflammation among married couples, and whether one partner’s sleep affected the other’s inflammation,” said Stephanie Wilson, Ph.D., lead researcher on the study.

Results of the study were published in the journalĀ Psychoneuroendocrinology.

The research team recruited 43 couples who completed two study visits. The couples provided blood samples and said how many hours they had slept the previous two nights.

Then researchers had the couples try to resolve a topic that sparks conflict in their marriage. Blood samples were taken again following the discussion.

“We found that people who slept less in the past few nights didn’t wake up with higher inflammation, but they had a greater inflammatory response to the conflict. So that tells us less sleep increased vulnerability to a stressor,” Wilson said.

“Any increase isn’t good, but a protracted increase that isn’t being addressed is where it can become a problem,” Wilson said.

“What’s concerning is both a lack of sleep and marital conflict are common in daily life. About half of our study couples had slept less than the recommended seven hours in recent nights.”

That’s higher than the current national average. The CDC reports 35 percent of Americans get less than seven hours of sleep per night.

“Part of the issue in a marriage is that sleep patterns often track together. If one person is restless, or has chronic problems, that can impact the other’s sleep. If these problems persist over time, you can get this nasty reverberation within the couple,” said Janice Kiecolt-Glaser, Ph.D., senior author and director of the Institute for Behavioral Medicine Research.

Researchers were encouraged to see that there was a protective effect if one of the partners was well-rested, or discussed conflict in a healthy way. They tended to neutralize the disagreement that might be stirred by the sleep-deprived partner.

“We would tell people that it’s important to find good ways to process the relationship and resolve conflict — and get some sleep,” Kiecolt-Glaser said.
