Many people will have the experience of dizziness and drowsiness in the case of overuse of the brain, mainly because in the process of brain activity of long duration and excessive intensity, the cellular metabolism of the brain produces some products, such as free radicals, lactic acid and other harmful substances in large quantities, blocking the nutritional channels of the brain, which will lead to the disruption of the brain nerve function of patients. At the same time, it causes the patient’s brain blood oxygen content to be reduced, blood circulation to be poor, brain nutrients and energy to be extremely depleted and the absorption and utilization of nutrients to be hindered, which will lead to the inhibition of the vitality of the patient’s brain cells and the symptoms of dizziness, as well as the fluctuation of blood pressure under the condition of fatigue, which will cause the patient to have dizziness and headache.
