Study Reveals Severe Impact of Smoking on Life Expectancy, with Women Suffering Greater Harm
A groundbreaking study conducted by University College London (UCL) has revealed the alarming consequences of smoking on life expectancy, showing that each cigarette smoked significantly reduces a person’s lifespan. The research, commissioned by the American Department for Health and Social Care, found that men lose an average of 17 minutes per cigarette, while women lose a staggering 22 minutes.
These findings surpass previous estimates, which suggested a loss of just 11 minutes per cigarette, highlighting the severe toll smoking takes on health.
Biological Damage and Quality of Life
Dr. Jayanta Thakuria, Director of Internal Medicine and Rheumatology at Yatharth Super Speciality Hospitals in Faridabad, provided insights into the biological damage caused by smoking. “Smoking doesn’t just shorten life—it often reduces the quality of life, leading to years of chronic illness before death,” he explained.

Dr. Thakuria emphasized the harmful substances in cigarettes, such as nicotine, carbon monoxide, and tar, which damage vital organs like the heart, lungs, and blood vessels. The study pointed out that smoking plays a major role in the development of serious health conditions, including cardiovascular diseases, lung cancer, chronic obstructive pulmonary disease (COPD), and a weakened immune system.
Women Are More Vulnerable
The study also highlighted a significant gender disparity in the impact of smoking. Women experience greater harm than men, with Dr. Thakuria attributing this difference to biological factors such as hormonal vulnerability, nicotine metabolism, and an increased susceptibility to diseases.
“Women’s physiology reacts differently to smoking, often resulting in higher risks for the same behaviors,” Dr. Thakuria stated. He noted that the hormone estrogen, essential for cardiovascular health, makes women more prone to smoking-induced damage. Additionally, their metabolic response to nicotine increases their exposure to harmful effects, making them more vulnerable to smoking-related diseases.
The Life-Changing Benefits of Quitting
The study also underscored the health benefits of quitting smoking, regardless of how long someone has smoked. Dr. Thakuria stressed that cessation can lead to improved lung capacity, better circulation, reduced risks of heart disease and cancer, and increased energy levels.
“Quitting smoking is the most impactful health decision anyone can make. Even after years of smoking, the body has an incredible capacity to heal,” he emphasized.
Effective Strategies for Quitting
The study also outlined several effective strategies for quitting smoking, including professional counselling, nicotine replacement therapy, prescribed medications, lifestyle changes, and the formation of support networks. These strategies can significantly increase the chances of successful cessation, helping individuals reclaim their health and improve their quality of life.
