What happens to your body if you stop smoking

Experts have shown numerous times that smoking has a negative impact on our bodies as a whole. But for many people, quitting smoking is a very serious psychological challenge, or they simply find they don’t have the motivation to make the change in their lifestyle.

We believe a healthy lifestyle is hugely important and would, therefore, like to share with you some important information about what happens to a person’s body when they give up smoking.


Experts at the Centers for Disease Control and Prevention (CDC) have produced data showing the changes that occur when a person gives up unhealthy habits.

Incredibly, just 20 minutes after you finish your last cigarette, a series of positive changes begins that will last for years.

20 minutes

The functioning of your heart returns to normal. Your capillaries and the vascular network are restored to health. Blood flow improves, and the sensitivity of your feet and fingers increases.

After 8 hours: Carbon monoxide, which can be toxic to the body at high levels, is released from burning tobacco and inhaled as part of cigarette smoke. In just 8 hours, the carbon monoxide in your body decreases to lower levels, and your blood oxygen levels increase to normal.

12 hours

The level of carbon monoxide in your blood falls, whilst the level of oxygen increases. The composition of the blood returns to normal.

After 48 hours: it may not be life-threatening, but deadened senses, especially smell and taste, are one of the more obvious consequences of smoking. But after 48 hours without a cigarette, your nerve endings will start to re-grow, and your ability to smell and taste is enhanced.

From 2 weeks to 3 months

The risk of heart attack is reduced. The symptoms of tobacco addiction disappear. Blood circulation in the peripheral vessels improves. Lung tissue is restored and the function of the lungs significantly improves.

After 72 hours: Your lungs start to revitalize and you now have the ability to produce deeper breaths, The cilia in your lungs will start to repair itself and the risk of heart attack lowers even more.

After 2 weeks: Remember that sick feeling you got everytime you exercised? Well, after two or three weeks, you’ll be able to perform physical activities without that nauseating feeling. This is due to the fact that your lungs have started to clear, and it will be easier to breathe.

After 3 to 9 months: Your skin will start to look and feel soft again. Your blood circulation will improve and your skin produces more collagen. This means your skin puts off the creation of wrinkles.
