The researchers found that sociability good for your health, while loneliness is equivalent to 15 cigarettes a day.
Alcohol, cigarettes and a sedentary lifestyle - can cause serious health problems. But good friends and talk from the heart, can rectify the situation.
Physiologists have found that close friends and strong family ties can improve your health more than exercise, losing weight, throwing these bad habits like smoking and drinking alcohol.
Friendly people are less stressed, better look after their well-being, are less risky behaviors than those who live in isolation.
The scientists analyzed a study on the impact that relationships have on health. It turned out that the people who belong to any social group (friends, neighbors, relatives, or all of them together) are 50% more likely to survive.
The data obtained so startled researchers, it caused them to turn to doctors and to the Ministry of Health, with a call to equate loneliness to alcoholism and smoking.
"People perceive the relationship for granted," - said Julianne Holt-Lunstad, a psychologist at the University of Brihama Young in Utah. "This cooperation is not only beneficial effect on our mental state, but also on our physical health."
Team Holt-Lutstad analyzed 148 studies in which monitored the impact of social interaction on the health of 308,849 people who took part in the study for an average of 7.5 years. The data allowed to determine the impact of premature death has a communicative person.
It was found that loneliness in terms of the negative effects equivalent to smoking of 15 cigarettes per day or to alcoholism. It is also harmful as lack of exercise, and two times worse than to be overweight. The study was published in the journal Plos Medicine.
Holt-Lunstad said that friends and family can improve health in the broadest sense, for example, to find the meaning of life in difficult times. "When a person feels a part of the group and feels responsibility for other people, it gives purpose and meaning to life, and this leads to a more thorough tracking of their well-being and a reluctance to go to unnecessary risk.
According to Holt-Lunstad, there is no any clear number, which determines the minimum required communication. But health is better for those people who rarely feel lonely and feel the support of a group of friends, have a strong family and who is the one to whom you can trust and who you can trust.
In the published paper, the authors noted that the doctors and the media are serious dangers of smoking, unhealthy diet and lack of exercise, and tell them to add to this list of social relationships.
A report by mental health, which was published in May, says the negative impact of technology and pressure of modern life to the widespread feeling of loneliness among all age groups in Britain. Survey of more than 2,200 adults showed that 1 out of 10 often felt lonely, and one in three would like to move closer to his family.
Andrew MakKulloch, from the organization of mental health, said the latest studies confirm the link between isolation and poor mental and physical condition. "The trend towards ever-increasing number of single people because of new technology is changing the way of interaction between people and leads to the fact that both young and adults experiencing loneliness. Important to ordinary people, along with lawmakers, took note of the findings of the potential harmful effects of that loneliness has on health. "
