Medical facts about smokers

It is significant that the pulse rate and blood pressure strength in smokers is higher than in nonsmokers. This is due to the effect of nicotine on the vagus and sympathetic nerves, as well as on the vasomotor center in the brain. Nicotine acts on the work of the adrenal glands, which secrete in its presence an increased amount of adrenaline.

Stopping smoking causes a decrease in heart rate and blood pressure. Observations of a large group of people who quit smoking showed that within a day they had significant changes. The pulse on the day of quitting smoking averaged 94, after a day it became 79. Blood pressure also dropped significantly.
