Brits are being told of what could happen to their bodies within just half an hour of ditching nicotine.

Withdrawal symptoms can make it notoriously difficult to give up smoking, but those who push through will notice the first health improvements in less than half an hour after stubbing out the last cigarette. In just 20 minutes, the heart rate and blood pressure start to drop back to normal and many people experience their hands and feet warming up because of better circulation.

In eight hours, half the amount of nicotine and carbon monoxide in the blood will be eliminated, and within a single day the bloodstream will be almost nicotine-free. In just a month’s time, people will struggle less with shortness of breath and experience improved energy levels. Over the long term, the risk of developing life-threatening conditions such as cancer, heart disease, and stroke continues to decline.

Ashleigh Tosh from Prepped Pots powered by MuscleFood.com said: “Breaking free from nicotine addiction is not easy but once you stop smoking your body and mind will begin to repair itself. It will take some time for your body to heal entirely, however small health improvements start to occur as soon as 20 minutes after smoking your last cigarette. These include reduced blood pressure and heart rate.

“As time progresses, the body repairs more and more damage caused by nicotine, resulting in improved circulation, energy levels, lung function and sense of smell and taste, as well as reduced risk of life-threatening conditions. While the initial withdrawal period may be challenging, breaking the cycle of addiction is great for your mental well-being, contributing to improved mood, reduced anxiety, and enhanced cognitive function.”

Here are the seven health benefits of quitting smoking:

Improved cardiovascular health

Within just minutes of quitting, heart rate and blood pressure begin to decrease, reducing the strain on the cardiovascular system. Over time, the risk of heart disease, heart attack, and stroke lowers significantly.

Healthier lungs

After quitting nicotine, the lungs start to repair themselves which leads to improved lung function. People experience less coughing, wheezing and shortness of breath. This makes it easier to exercise and carry out physical activities without feeling out of breath.

Heightened sense of taste and smell

Smoking damages the nerve endings responsible for the senses of smell and taste. Within around a week after quitting, these senses start recovering so you can begin enjoying food and aromas more.

More energy

Many people experience a boost in their energy levels after giving up. That’s because ditching smoking allows for better oxygen flow to vital organs and tissues and this increased oxygen supply boosts energy levels.

Improved oral health

Quitting smoking will prevent further tooth discolouration, restore your gum health over time and contribute to fresher breath.

Reduced risk of cancer

Smoking can cause cancer almost anywhere in the body but quitting can significantly lower the risk. The risk of mouth and throat cancer drops by half in five years, while it takes around ten years for lung cancer.

Better mental health

Quitting nicotine has positive effects on mental well-being, reducing symptoms of anxiety and depression. Cognitive function improves, leading to better concentration, memory, and overall mental clarity.
