What Happens when one stops smoking
It should come as no surprise that smoking is one of the major causes of avoidable deaths globally, with over 7,000 chemicals emitted with each cigarette you light. However, with 1.3 billion people now smoking, what happens after you stop? Your heart rate and blood pressure return to normal within the first 20 minutes of quitting. This is because smoking causes the release of adrenaline and norepinephrine, which quicken the heartbeat and constrict the blood vessels. As a result of these effects, smokers' extremities also felt colder, but by this point, your hands and feet have warmed back to normal. Two hours later, nicotine cravings start to set in, resulting in irritability, drowsiness, tension, and even trouble sleeping because nicotine also releases more dopamine than usual.These physiological reactions to a decrease in its release are to be expected.
