A recent study from University College London (UCL) reveals that smoking a single cigarette can shorten your life by 20 minutes. This is nearly double the previous estimate of 11 minutes. The research, commissioned by the Department for Health and Social Care, analyzed data from long-term population health studies.

The study highlights the importance of quitting smoking. If a smoker quits by August 5, they could gain a full month of life expectancy compared to continuing the habit. The harm caused by smoking is cumulative. The sooner a person quits, and the more cigarettes they avoid, the longer they are likely to live.

The study also shows a gender difference. Men lose 17 minutes for every cigarette smoked, while women lose 22 minutes. This suggests smoking has a more significant impact on women’s health. Smoking contributes to preventable diseases like heart disease, stroke, and various cancers.

Researchers stress that quitting smoking can lead to immediate health improvements. A smoker who quits sees better heart health and a reduced risk of heart attacks. The damage caused by smoking builds over time, so quitting sooner offers greater benefits.

This study serves as a stark reminder of the dangers of smoking. Each cigarette shortens life expectancy, but quitting can reverse some of this damage. By quitting, smokers can live longer and improve their overall health.
