After 7 days without smoking, the carbon monoxide in your blood drops to normal levels, significantly increasing oxygen, while your nerve endings start to regrow, improving your senses of taste and smell, though you'll likely still experience strong cravings and withdrawal symptoms like irritability and difficulty concentrating as your body adjusts. You'll notice easier breathing and circulation improvements, marking the start of major healing as your lungs and body clear toxins and repair damage, making the first week the toughest but most crucial for long-term success.
Within one week your sense of taste and smell may have improved. Within three months you will be coughing and wheezing less, your immune function and circulation to your hands and feet will be improving, and your lungs will be getting better at removing mucus, tar and dust.
The first seven to 10 days are the toughest, and you may need the most help during these early days. Most people who smoke and use tobacco products return to doing so within the first three months. "Slips" (having a puff, smoking one or two cigarettes, getting some hits off a vape pen or e-cigarette) are pretty common.
When you quit smoking or vaping, you will have withdrawal symptoms. These can last from a few days to a few weeks – it's different for every person – but they are temporary. The first week is the hardest as your body has become used to having regular nicotine 'hits'.
This is because your body and brain have become dependent on nicotine, and as you begin to starve yourself of the drug, your dopamine levels are significantly reduced. As the “feel-good” neurotransmitter1, these reduced levels of dopamine are the key reason for feeling depressed after quitting smoking.
1 week after quitting: breathing feels easier
The inflammation in your airways also begins to decrease, which allows more air to flow in and out of your lungs. You might find physical activities—like walking up stairs or exercising—are less tiring because your lungs are starting to regain their strength.
Within weeks of giving up
After you've stopped smoking for a few weeks, you'll start to see even more benefits. As early as two weeks after you stop, your blood circulation and energy levels will start to improve. After a month, you might notice that your skin looks better and any facial wrinkles might be reduced.
After 48 hours
Your carbon monoxide levels have dropped to that of a non-smoker.
2. What Are Some Natural Ways to cleanse Your Lungs?
Half the people who quit smoking gain less than the average 6 to 10 pounds. And, about 1 of every 10 ex-smokers gains as much as 25 to 30 pounds. People usually gain the most weight in the first six months after quitting.
Relapses can occur at any time. Most relapses occur within the first 24 hours of quitting, but they are not unusual after seven days, fourteen days, thirty days or ninety days without tobacco.
Take Vitamins
Vitamins A and C are extremely important (as stated above), while vitamins K and D can also be beneficial to skin health. Look for a well-known daily vitamin with high levels of each of these essential vitamins.
When you quit smoking, you may experience the “icky threes”: extra challenges on day 3, week 3, and month 3 of not smoking. In other words, you may experience additional side effects at the third day, third week, and third month after quitting smoking. Not everyone experiences the icky threes.
During the first few weeks of quitting, try to avoid situations where you will be tempted to smoke and where cigarettes are available. Tell the people you spend time with who smoke that you are quitting smoking. Ask them to support you by not smoking around you and not offering you cigarettes.
Behavior change can be conceptualized into five progressive stages: precontemplation, contemplation, preparation, action and maintenance (below). Research states that in a given population, 40% of people who use tobacco are not ready to quit, 40% are thinking about quitting, and 20% are ready to quit.
Replace tobacco or nicotine with gum, a healthy snack or a mint. Give your mouth something to do to resist a craving. Chew on sugarless gum, or munch on raw carrots, nuts or sunflower seeds. Keep mints or candy on hand for a burst of something tasty.
Symptoms
Tea and Diet: Incorporating antioxidant-rich teas like green tea and chrysanthemum tea can help reduce inflammation in the lungs and improve overall lung health. Foods rich in vitamins, such as leafy greens, apples, and beets, also support lung function.
The vast majority of ex-smokers cannot have “just one.” Research shows that if you have even one cigarette after quitting, there is a 90% chance that you will return to regular smoking!! That's right–for every 10 ex-smokers who have a cigarette after quitting, 9 end up returning to regular smoking.
Quitting smoking can lead to significant improvements over time. Lung function and health may partially recover, with reduced inflammation and improved cilia function, but some damage, especially from long-term smoking, can be permanent.
Get Moving. Studies show that aerobic exercise can increase dopamine levels in your brain, particularly if you do it on a regular basis. It's best if you find time in your schedule to exercise consistently – whether it's going for a brisk-walk in the park or hitting the gym to for weight training.
Promoting Arterial Healing
Focus on a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Regular physical activity improves blood flow, supports cardiovascular health, and aids in artery healing.
There are usually four stages smokers go through in the process of quitting, which include:
10 days – Cravings are beginning to subside substantially. 10 days – 2 weeks – Blood circulation has recovered and even peripheral organs such as gums and teeth are enjoying the same circulation levels as those of a non-smoker.
