The significance of vacation and leisure is reflected in five aspects: (1) Vacation and leisure is a synergist for cancer treatment. If tumor patients can cooperate with vacation and leisure during treatment, it can undoubtedly make the treatment “multiply with half the effort”. (2) Vacation and leisure is a release agent of bad emotions. Undoubtedly, tumor patients are troubled by cancer, and most of them are bitter, anxious, pessimistic and disappointed, and these bad emotions are like shadows over their hearts, which are very unfavorable to the treatment and recovery. Vacation and leisure activities are the “releasing agents” of bad emotions, which can free patients from tension and release the “bad factors” such as anxiety and pessimism through leisure travel, so that the negative psychological pressure inside can be improved and the immune function can be mobilized. This will help to mobilize the immune function and help to overcome the cancer. (3) Vacation and leisure are the enhancers of recovery As for patients in treatment, patients in recovery need vacation and leisure even more. Because it is a recovery enhancer. (4) Vacation and leisure activities reflect the change of modern medical model Science is developing, and the purely physiological medical model has become obsolete, replaced by the physiological-psychological-social medical model, which emphasizes the psychological state and the social factors. Vacation and leisure activities can better solve the closed psychological state of patients, make them go to the society, integrate into the group, and receive psychotherapy intentionally or unintentionally. This is incomparable to simple drug treatment. (5) New medical cultural concept of vacation and leisure activities Vacation and leisure activities are also a kind of treatment method and a medical cultural activity for cancer patients, because the leisure activities inevitably contact with local customs, famous people and anecdotes, humanistic landscape, and can also arrange fishing, mountain climbing and sightseeing, which all reflect the charm of culture. It is undoubtedly beneficial to the physical and mental health of cancer patients, so it is not too much to call “vacation and leisure” as medical culture.
