Candidates should avoid changing their diet before exams
Candidates' diets should not be deliberately changed due to the approaching exam. In the period before the exam and during the exam, the amount of food should not increase much more than usual, especially during the exam period. The diet should remain consistent with normal times.
The diet should never skimp on staple foods
Candidates' diets must ensure adequate intake of staple foods. Previously, people often thought staple foods were optional, as long as they ate more fish and meat. In fact, these foods only supplement the protein the body needs, while brain function primarily relies on glucose. Only staple foods can be converted into glucose, which means a certain amount of staple food must be consumed daily. Experts emphasize: "Not eating staple foods not only causes hunger but also impairs cognitive function."
Coffee can cause frequent urination
Candidates should drink plenty of water before exams, ensuring an intake of 1500 to 2000 milliliters per day. Beverages should not be used as a substitute for water; plain water is best, and mineral water or purified water are also good choices. Adequate water ensures smooth blood circulation, allowing the brain to receive a timely supply of oxygen.
