With over seven thousand chemicals released each time you light a cigarette,
it’s no surprise that smoking is one ofthe leading causes of preventable death worldwide.
But with 1.3 billion people actively smoking,
what actually happens when you stop smoking?
Within the first 20 minutes of quitting, your blood pressure and heart rate will return to normal.
This is because the nicotine in cigarettes released epinephrine and norepinephrine,
which increase your heart rate and narrowed blood vessels.
These facts also cause smokers extremities to feel colder,
but by now your hands and feet have returned to their normal temperature.
2小时过后 你对尼古丁的渴望会造成闷闷不乐、困倦、 紧张等感受
2 hours in, and the nicotine cravings begin causing moodiness, drowsiness, tense feelings,
and even difficulties sleeping,
because nicotine also releases more dopamine than normal.
These are expected physiological responses to the decrease and its release.
8 hours after quitting, an inhaled carbon monoxide clears,
allowing oxygen levels in the blood stream to return to normal.
Carbon monoxide and oxygen compete to bite hemoglobin in your blood,
which stresses the circulatory system.
So as it clears, there is more room for oxygen.
However, for the longterm smokers,
this carbon monoxide exposure causes red blood cells to increase in size,
making the blood thicker, and causing higher blood pressure,
and increases chances of developing blood clots.
Surprisingly, 24 hours after quitting,coughing will actually increase,
which is your body’s way clearing out all the toxins from the lungs.
Additionally, at this point, the risk of developing various coronary heart diseases decreases,
all within 24 hours.
After 48 hours, when nicotine and its metabolites are completely eliminated from your body,
damaged nerve endings begin to regrow.
香烟中还有焦油和其它化学物质 随着血管中这些物质含量的减少 味蕾上的含量也在减少
The tar and other chemicals in cigarettes leave fewer taste buds that are fluttered with less blood vessels.
They now begin to regain their sensitivity, making food taste better.
Although chronic smokers may often have irreversible damage to taste buds.
戒烟72小时时 尼古丁戒断高峰症状出现包括头痛 恶心 痉挛
At the 72-hour mark, nicotine withdrawal peaks with headache, nausea, and cramps,
as well as emotional symptoms like anxiety and depression.
These symptoms can be seen by most addictive substances including caffeine.
But after this period, the worst is officially over.
After one month, the risk of developing Type II diabetes,
cancer and cardiovascular diseases has already decreased.
In 3-9 months, the damaged cilia in the lungs are almost fully repaired,
which are hair-like structures that helps sweep away dust and debris.
And as a result, symptoms such as coughing and shortness of breath are almost completely eliminated.
And around one year, the risk of developing heart disease, as a direct result of atheroma formation,
which are deposited fat material or scar tissues from deteriorating arterial walls,
decreases by almost one half.
In 10 years, the chance of developing lung cancer decreases to
half of someone who did not quit smoking.
And in 15 years’ time, the risk of heart attack decreases to
the same as someone who has never smoked in their entire life.
Of course, this guideline is not definitive,
and the average amount you smoke per day or year will play a role in how well your body recovers.
Unfortunately, there will always be some irreversible damage to the lungs,
and increasing susceptibility to developing various lung diseases.
And, while quitting may be difficult, the benefits greatly outweigh the initial withdrawal.
Ultimately, the best way to prevent this from happening is to not begin smoking at all.
