In some patients, nervousness can lead to an increase in low blood pressure, especially for patients with cardiac neurological dysfunction and patients with vegetative neurological dysfunction, after nervousness, the secretion of the renin-angiotensin-aldosterone system is imbalanced and an increase in blood pressure occurs due to the dysfunction of the neurological-humoral-endocrine system. In addition, excessive contraction of capillaries occurs when a person is stressed, and an increase in blood pressure also occurs when capillaries are over-constricted. Therefore, for patients with previous hypertension, it is not recommended to be overly tense, anxious, agitated, or to have sympathetic over-excitement, etc. Because the increase in blood pressure after a person has been tense will also result in the impairment of the function of the corresponding target organs and organs, so once caused by the increase in low pressure, it is necessary to take a rest in time, and certain medicines can be applied to symptomatic treatment.
