With high pace of modern society, more and more people get stressed and feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are different types of loneliness.
The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and doesn’t require any specially attention. The second kind, situational loneliness, is a natural result of a particular situation ―for example, when a family problem appears, the time a loved one dies, or when they move to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year. The third kind of loneliness is the most severe. Unlike the second type, it usually lasts for more than two years and has no specific cause. People in this case have problems socializing and can not become close to others. Unfortunately, many such people think there is little or nothing they can do to improve their condition.
Psychologists are trying to find ways to help habitually lonely people for two reasons: They are unhappy and unable to socialize and there is a connection between habitual loneliness and serious illness such as heart disease. While temporary and situational loneliness can be normal, healthy part of life, habitual loneliness can be a very sad, and sometimes dangerous condition.
