Brain function is not a constant. It depends on a variety of factors, ranging from personality traits (e.g., whether you're a morning person or night owl) to level of fatigue and current state of health. By observing yourself, you can determine the cause-and-effect relationship between your performance and the factors that influence it. But there is a universal advice - if you feel that you feel that you start to lose your mind, drink some water. Dehydration does not immediately cause thirst, but it can affect the processes in the body very substantially.
