Psychological conditioning: learn to relieve stress, vent bad emotions and relax yourself. We can take concrete measures, such as exercise, listening to music, taking a deep breath, talking with others, traveling and so on. In work and study, we should keep calm and cheerful, be tolerant of others, don't get bogged down, establish a correct outlook on life and values, cherish the meaning of life, have a broad mind, regard life as an endless journey of interest and appreciate the universe. Exercise conditioning: pay attention to the combination of work and rest, avoid high-intensity and fast-paced blind running, long-term mental stress and serious fatigue, and neglect self-physical and mental health care. We should adjust and rest properly, avoid continuous fighting and sleepless nights, control and reduce unnecessary social entertainment and nightlife, ensure adequate sleep, strengthen physical exercise, and don't give up physical exercise because of busy work. Diet: Pay attention to the taste, add more protein, fat and vitamins, eat more vegetables and fruits, eat more fish, poultry and foods rich in fiber, quit smoking and limit alcohol.
