A
Most people 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 three different types of loneliness．
The first kind of loneliness is temporary（暂时的）．This is the most common type．It usually disappears quickly and does not require any special attention．The second kind, situational loneliness, is a natural result of a particular situation--- for example, a family problem, the death of a loved one, or moving 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, chronic（长期的）loneliness usually lasts more than two years and has no specific cause．People who experience habitual loneliness have problems socializing and becoming close to others．Unfortunately, many chronically lonely 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 chronic loneliness and serious illness such as heart disease．While temporary and situational loneliness can be a normal, healthy part of life, chronic loneliness can be a very sad, and sometimes dangerous condition．
