Then，consider this：you might be in a state of subhealth (亚健康)．

　　Subhealth，also called the third state or gray state，is explained as a borderline state between health and disease.

　　According to the investigation (调查) by the National Health Organization，over 45 percent of subhealthy people are middle­aged or elderly.The percentage is even higher among people who work in management positions as well as students around exam time.

　　Symptoms (征兆) include a lack of energy，depression (压抑)，slow reactions，insomnia (失眠)，agitation (焦虑)，and poor memory.Other symptoms include shortness of breath，sweating and aching in the waist and legs.

　　The key to preventing and recovering from subhealth，according to some medical experts，is to form good living habits，alternate work and rest，exercise regularly，and take part in open­air activities.

　　As for meals，people are advised to eat less salt and sugar.They should eat more fresh vegetables，fruit and fish because they are rich in nutritional (营养的) elements—vitamins and trace elements (微量元素)—that are important to the body.

　　Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract (消化道)．They also say that a balanced diet is very helpful in avoiding subhealth.
