Both high blood pressure and abnormally low blood pressure can have a negative effect on thinking ability, according to a study.
Chinese medicine sees problems of the mind as circulation problems. High and low blood pressure are both circulation problems. When circulation is poor, the brain doesn’t get enough oxygen and thinking is impaired.
A more technical explanation for the interested reader: Both high and low blood pressure are caused by stagnation of blood. Low blood pressure is a case of Deficient Fire. High blood pressure is a case of Excessive Earth, which also decreases Fire. Decreased Fire means decreased mental abilities.
