Normal brain use does not need to be adjusted, but if you use your brain at ordinary times, you will be prone to hypoxia or anger, which will accelerate the aging of brain cells. For example, when angry, a large amount of blood rushes to the brain, which will increase the pressure on the cerebral vessels. At this time, the toxins contained in the blood will seriously harm brain cells. I suggest you eat more crude fiber foods such as broccoli and Chinese cabbage, expel toxins from your body, and cooperate with some conditioning prescriptions of Heyang Decoction to protect brain cells.
