Caffeine does not increase the basic knowledge of hypertensive coffee

Abstract: any coffee (caffeinated or not) can raise blood pressure in people who don't usually drink coffee much, according to a study. They also found that when regular coffee drinkers drank coffee, their sympathetic channels were stimulated, but their blood pressure did not rise.

Caffeine may not raise blood pressure, because decaffeinated coffee also raises blood pressure, Swiss researchers say. It may be other substances in coffee that raise blood pressure.

Dr Roberto Corti of the University of Zurich Hospital, who led the study, said: "until now we have blamed caffeine for the cardiovascular effects of coffee, but we have found that people who don't drink coffee usually have this effect when they drink decaffeinated coffee."

"it shows that we know very little about coffee, one of the world's most consumed stimulants and one of the most popular beverages," he said. "

The team found that any coffee, whether caffeinated or not, raises blood pressure in people who don't usually drink coffee much. They also found that when regular coffee drinkers drank caffeinated coffee, their sympathetic channels were stimulated, but their blood pressure did not rise.

The activity of the sympathetic nervous system can help regulate blood pressure. It is believed that hyperactivity of the sympathetic nervous system is associated with high blood pressure. (ethnic Medicine Daily)
