A few days ago, I had dinner with some friends, and one of them mentioned that drinking alcohol can lower blood pressure. He said that after he drank, he went to measure his blood pressure, and it had dropped—so he found it strange.

Another friend is a doctor, so he explained the principle, and everyone was startled. After drinking alcohol, it can cause blood pressure to expand (i.e., the blood pressure drops), but then the blood vessels will respond with retaliatory constriction, and blood pressure will rise again.
A few hours later—right up until the next day—blood pressure will continue to rise.
Moreover, this retaliatory constriction causes serious damage to the blood vessel endothelium.
For people with hypertension, drinking alcohol is likely to trigger cardiovascular and cerebrovascular accidents.
