 Having frequent arguments with partners, friends or relatives can increase the risk of death in middle-age, say Danish researchers. 
  
 Writing in the Journal of Epidemiology and Community Health, they said men and those not in work were most vulnerable. 
  
 Dealing with worries and demands from close family was also linked to a higher mortality risk, the study said. 
  
 An individual's personality and ability to deal with stress is likely to play a role in the findings. 
  
 Intervening in conflicts, particularly for those out of work, may help to curb premature deaths associated with social relationship stressors. Dr Rikke Lund, University of Copenhagen 
  
 Although the research team, from the University of Copenhagen, calculated that constant arguing increased a man or woman's mortality risk by two or three times the normal rate, they could not fully explain the factors behind it. 
  
 Previous research suggests people with high levels of anxiety and demands from partners and children, and those who often argue with close family members, could be at a higher risk of heart disease and strokes. 
  
 Past studies also suggest that a good social support network and a wide network of friends have a positive impact on health, while personality determines, to a large extent, how we perceive and react to social situations and relations. 
  
 In this study, the researchers said physiological reactions to stress, such as high blood pressure and an increased risk of cardiovascular disease, were most likely to explain the increased mortality risk. 
  
 The study said: "Men respond to stressors with increased levels of cortisol, which may increase their risk of adverse health outcomes." 
  
 Out of work 
  
 Data on 9,875 men and women aged between 36 and 52 was used to explore the relationship between stressful social relations and premature death.

 They had all taken part in the Danish Longitudinal Study on Work, Unemployment and Health, from 2000. 
  
 The study found that frequent worries or demands generated by partners and children were linked to a 50%-100% increased risk of death from all causes. 
  
 Being out of work seemed to increase the negative impact of stressful social relationships. Those who were unemployed were at significantly greater risk of death from any cause than those who had a job, the study said. 
  
 Men seemed to be particularly vulnerable to the worries and demands generated by their female partners, with a higher risk of death than that normally associated with being a man. 
  
 Dr Rikke Lund, from the University of Copenhagen's department of public health, said worries and arguments were part of life. 
  
 But she added that people who were always or often involved in conflicts were at greatest risk, and could be helped. 
  
 "Intervening in conflicts, particularly for those out of work, may help to curb premature deaths associated with social relationship stressors," she said. 
  
 Prof Angela Clow, from the department of psychology and physiology at the University of Westminster, said the findings were "not surprising". 
  
 "It would have been more interesting if they had looked at the biological pathways and shown why or how conflicts had an effect on mortality risk," she said. ||||| People who frequently argue with family and friends, or worry too much about their loved ones, may have triple the risk of dying early in middle age, compared with those who are less argumentative, a new Danish study suggests. 
  
 The researchers found that unemployed men in particular seemed most vulnerable to stresses caused by constant conflicts with friends or family. 
  
 "Having an argument every now and then is fine, but having it all the time seems dangerous," said study researcher Rikke Lund, an associate professor of medical sociology at University of Copenhagen. 
  
 The study included nearly 10,000 men and women ages 36 to 52, who answered questions about their everyday social relationships in 2000. The participants were asked how often they had conflicts with their partners, their children, friends or neighbors, and whether they experienced worries about and demands from their friends and family members.

 By 11 years later, 196 women (4 percent) and 226 men (6 percent) had died. Almost half the deaths were from cancer, and the rest were due to heart disease, accidents, suicide and liver disease from alcohol abuse. 
  
 The researchers found that the people who had reported frequent conflict with someone in their social circle had two to three times higher risk of dying during the study period, compared with those who did not report frequent conflicts. 
  
 Those who reported worries about and demands from their partners or children had a 50 to 100 percent increased risk of death, the researchers said. 
  
 "Worrying about people is a character of us loving them," Lund said. "It's just when it takes up all of your time that it's unhealthy." 
  
 The results held when the researchers controlled for factors that may influence people's risk of dying, such as their gender, age, job and social class, and whether they had any major health condition in the past, according to the study published today (May 8) in the Journal of Epidemiology & Community Health. 
  
 Constantly stressful social relations likely increase people's risk of dying through not just one, but multiple pathways, the researchers said. Previous research has suggested a link between stressful social relations and health, and some studies have found higher rates of heart disease among people who experience conflicts or worries from social relations, the researchers said. 
  
 It is possible that people who are exposed to stress are more likely to take on risky health behaviors such as smoking and drinking, or to become depressed or obese. These factors could in turn increase their risk of dying early, Lund told Live Science. 
  
 "Having these types of stressful relations can lead to bodily symptoms which have been shown before to increase the risk of high blood pressure. These effects on the body might be part of the explanation for the connection between stress and mortality 10 years later," Lund said. 
  
 People may also perceive and deal with stressful relationships in different ways depending on their personalities, Lund said. 
  
 The researchers found that unemployment amplified the effects of stressful social relationships. Those who were unemployed had a higher risk of dying early than those who had similar stress but had a job. 
  
 In the study, about one in 10 participants said that their partners or children were a frequent source of excess demands and worries, and about one in 20 reported having frequent arguments with their partners or children. 
  
 About 2 percent of participants had frequent arguments with their other relatives, and 1 percent with friends or neighbors.

If you find yourself in frequent conflict with friends, family members, or neighbors, you might be arguing yourself into an early grave, a new study finds. Researchers say middle-aged people who have frequent arguments are two to three times more likely to die prematurely, with those who often squabble with neighbors especially likely to die early, reports the Los Angeles Times. People who often fretted about their spouse or children were also a lot more likely to die prematurely from a variety of causes, including cancer, heart disease, and alcohol abuse. The researchers, who studied data on thousands of Danish adults, found that unemployed men were the likeliest to have high levels of social conflict in their lives, the BBC reports. "Having an argument every now and then is fine, but having it all the time seems dangerous," the lead researcher tells LiveScience, explaining that people with stressful social relations not only have higher blood pressure, but are more likely to engage in risky behavior like smoking or excessive drinking. She says conflict management classes could be a good way for communities to curb early deaths.
