Smoking is the single most damaging habit for human health, affecting every organ in the body, according to board-certified heart surgeon Dr. Jeremy London. During an appearance on The Mel Robbins Podcast, Dr. London identified cigarette use as the primary behavior he avoids, citing its deadly risks.
Why is smoking considered the most dangerous habit?
Dr. London, a heart surgeon with over 25 years of experience, categorizes smoking as the top risk factor. He asserts that no other behavior inflicts as much damage across all organs in the body. While acknowledging that it is highly addictive, he maintains that the clinical evidence regarding its toxicity is irrefutable. According to the NHS, smoking can cause heart disease, cancer, vision loss, dementia, and high blood pressure.
The body begins a recovery process almost immediately after quitting. Within 20 minutes of your last cigarette, your pulse rate begins to return to a normal level.
How does the body recover after quitting?
Physiological repair begins shortly after cessation, according to data from the NHS. Within eight hours of stopping, the levels of carbon monoxide in the bloodstream are reduced by half, making room for more oxygen to flow through your body. Over a longer timeframe, the benefits become even more pronounced. For instance, after 10 years of abstinence, the risk of dying from lung cancer is half that of someone who still smokes.
What support is available for those looking to quit?
The NHS provides free, friendly local stop-smoking services staffed by expert advisers. These programs offer a range of proven methods to help you quit. Common options include:
- Nicotine Replacement Therapy: Methods to help you quit.
- Medicines: Drugs such as bupropion, which are designed to assist in the process.
