You improve your heart rate and blood pressure
Nicotine is a psychoactive substance known to increase heart rate and blood pressure and consequently the risk of stroke. It tightens important arteries, causing an irregular heart rhythm and making your heart work harder.
The good news is that most side effects of smoking on your heart rate and blood pressure go away twenty minutes after your last smoke. Apart from pulse and blood pressure, the temperature of your hands and feet go back to normal as well.
