Although some observers have suggested that crying is a way to elicit assistance from others(as a crying baby might from its mother), the shedding of tears is hardly necessary to get help.Vocal cries would have been quite enough, more likely than tears to gain attention. So, itappears, there must be something special about tears themselves.
Indeed, the new studies suggest that emotional tears may play a direct role in alleviatingstress. University of Minnesota researchers who are studying the chemical composition oftears have recently isolated two important chemicals from emotional tears. Both chemicalsare found only in tears that are shed in response to emotion. Tears shed because ofexposure to cut onion would contain no such substance.
Researchers at several other institutions are investigating the usefulness of tears as a means ofdiagnosing human ills and monitoring drugs.
At Tulane University’s Teat Analysis Laboratory Dr. Peter Kastl and his colleagues report thatthey can use tears to detect drug abuse and exposure to medication (药物), to determinewhether a contact lens fits properly of why it may be uncomfortable, to study the causes of“dry eye” syndrome and the effects of eye surgery, and perhaps even to measure exposureto environmental pollutants.
At Columbia University Dr. Liasy Faris and colleagues are studying tears for clues to thediagnosis of diseases away from the eyes. Tears can be obtained painlessly without invading thebody and only tiny amounts are needed to perform highly refined analyses.

It is no secret among athletes that in order to improve performance you’ve got to work hard.
However, hard training breaks you down and makes you weaker, it is rest that makes youstronger.
Improvement only occurs during the rest period following hard training. This adaptation isaccomplished by improving efficiency of the heart and certain systems within the musclecells.
During recovery periods these systems build to greater levels to compensate for the stressthat you have applied. The result is that you are now at a higher level of performance.
If sufficient rest is not included in a training program, imbalance between excess trainingand inadequate rest will occur, and performance will decline. The “overtraining syndrome(综合症)” is the name given to the collection of emotional, behavioral, and physical symptomsdue to overtraining that has persisted for weeks to months. It is marked by cumulativeexhaustion that persists even after recovery periods.
The most common symptom is fatigue. This may limit workouts and may be present at rest.The athletes may also become moody, easily imitated, have altered sleep patterns, becomedepressed, or lose the competitive desire and enthusiasm for the sport. Some will reportdecreased appetite and weight loss. Physical symptoms include persistent muscular soreness,increased frequency of viral (病毒性的) illnesses, and increased incidence of injuries.
The treatment for the overtraining syndrome is rest. The longer the overtraining has occurred,the more rest required, therefore, early detection is very important. If the overtraining hasonly occurred for a short period of time (e.g. 3-4 weeks) then interrupting training for 3-5 daysis usually sufficient rest. It is important that the factors that lead to overtraining be identifiedand corrected. Otherwise, the overtraining syndrome is likely to recur. The overtrainingsyndrome should be considered in any athlete who manifests symptoms of prolonged fatigueand whose performance has leveled off or decreased. It is important to exclude anyunderlying illness that may be responsible for the fatigue.
