Pay attention to the entry physical examination, keep emotional stability before the entry physical examination, do not be overly nervous, and ensure sufficient sleep. Pay attention to a healthy diet, try not to eat high-fat food and drink high-sugar drinks 3-5 days before the physical examination, so as to prevent abnormal results of blood glucose and blood lipid tests. Eat lightly the night before the physical examination, and try not to drink strong tea or coffee after 20:00 pm. Do not exercise strenuously, as strenuous exercise can have an impact on the heart, lungs and blood pressure. The morning of the physical examination should be fasting, and bring their identity documents to the check-up center for the relevant medical examination business.
