An increase in blood pressure the day after drinking is often due to the stimulation of the sympathetic nervous system by alcohol, which increases sympathetic excitability and accelerates the heart rate. Patients often feel dry mouth and thirst after drinking alcohol, and the increase in blood volume caused by the large amount of water intake can cause an increase in blood pressure. In addition, blood pressure is often stimulated by factors such as alcohol. For the initial period of drinking alcohol often causes vasodilation and a moderate decrease in blood pressure, while long-term heavy drinking can cause damage to vascular endothelial cells and the formation of vascular atherosclerosis, which can cause an increase in blood pressure. Therefore, for hypertensive patients as well as normal people, it is recommended to standardize work and rest and living habits, suggest a low-salt, low-fat diet, quit smoking and limit alcohol, and exercise appropriately, maintain an optimistic, positive and upbeat attitude towards life, pay attention to monitoring blood pressure, blood glucose, blood lipids, etc., and have regular medical check-ups and re-examinations in hospitals.
