Stressful relationships can lead to an earlier death, says a new Danish study published in the Journal of Epidemiology & Community Health, Medical Daily reports.

The researchers used data from the Danish Longitudinal Study on Work, Unemployment and Health, which included 9,875 men and women aged 36 to 52 years. The study tracked their health from 2000 to 2011 and found that people without jobs were the most susceptible.   

They measured stressful social relations, partners, children, relatives, friends, and neighbors and examined the answers to questions regarding these relationships. Ten percent of participants said that their partner or child was always the source of their worries; six percent said they always or often had conflicts with other family members; and two percent had conflicts with friends often or always.

The authors found out that the participants who were in stressful relationships had a 50 percent increase of death risk, but worries and demands were only associated with mortality risk if they were related to partner or children.  

The opposite of this is also true: A 2013 study found that being in love and having a fulfilling love life can help you to live longer.
