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.This is the most common type.It usually disappears quickly and does not require any special attention.The second kind is situation，for example，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 serious.Unlike the second type，chronic(the opposite of “temporary”)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(心理学家)agree that one important factor in loneliness is a person's social contacts，for example，friends，family members，co?workers，etc.We depend on various people for different reasons.For instance，our families give us emotional support，our parents and teachers give us guidance，and our friends share similar interests and activities.However，psychologists have found that，though lonely people may have many social contacts，they sometimes feel they should have more.They question their popularity.

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 sad，and sometimes dangerous condition.

If you’re training for a marathon, a proper plan for water intake （摄入） is important. Of course, there’s the risk of dehydration （脱水）. But athletes now know they can also get into trouble by drinking to much . To much water intake can lower levels of sodium （钠） in the blood. The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research.

Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight.

One technique for deciding how much water you need is to get the exact numbers. Runners have to weight themselves before and after a run to determine how much water they’ve lost. If their weight drops by more than 2 percent, they have not drunk enough water.

Hyponatremia occurs when runners drink so much water that blood salt levels drop off. A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the hands. They can’t get their rings off, and then they might feel sick. They may not remember where they are. In fact, most runners get enough salt to get back to normal levels by eating just one meal after a run. Contrary to the old advice that runners should drink as much as they can to prevent dehydration, the new research has shown that the body is a remarkable machine that actually tells you via thirst when you need water.
