Study Shows that Adopting a Healthy Lifestyle at 40 Can Add 5 Years to Life and Counteract Genetic Risk

Adopting a Healthy Lifestyle at 40 Could Add Five Years to Life, Study Finds

A recent study published in BMJ Journals has revealed that adopting a healthy lifestyle at the age of 40 could potentially add five more years to one’s life. The study also found that this healthy lifestyle could counteract the impact of genes that shorten life spans by over 60%.

The researchers behind the study analyzed data from 353,742 individuals from the UK Biobank over a 13-year period. They assessed the participants’ genetic risk of early death using a polygenic risk score, categorizing them into short, intermediate, or long lifespans. Lifestyle quality was measured based on six factors: smoking, alcohol intake, physical activity, body composition, sleep duration, and dietary habits. During the follow-up period, 24,239 participants passed away.

Participants with a high genetic risk of shorter lifespans had a 21% higher chance of early death compared to those with low genetic risk, regardless of their lifestyle choices. However, individuals who led unhealthy lifestyles experienced a 78% higher probability of premature mortality, regardless of their genetic risks.

The study highlighted the combined influence of genetic disposition and lifestyle choices on lifespan, showing an additive impact. Participants who had both a genetic predisposition for a shorter lifespan and an unhealthy lifestyle faced double the risk of premature death compared to those without genetic risk factors but maintained healthier lifestyles.

Furthermore, the study suggested that individuals with a strong genetic risk of shorter lifespans could potentially add almost 5.5 years to their lives if they adopt a healthy lifestyle at the age of 40. The ideal combination of lifestyle habits includes not smoking, regular exercise, adequate sleep, and a healthy diet.

Researchers emphasized the importance of making lifestyle changes early in life to counteract the effects of genetic predispositions toward shorter lifespans. They noted that habits often become fixed by middle age, making it crucial to prioritize healthy living habits sooner rather than later.

“This study elucidates the pivotal role of a healthy lifestyle in mitigating the impact of genetic factors on lifespan reduction. Public health policies aimed at promoting healthy lifestyles could serve as potent complements to traditional healthcare and help mitigate the influence of genetic factors on human lifespan,” the researchers wrote.

The findings of this study underscore the importance of making proactive choices to prioritize health and well-being, especially as individuals age. By adopting a healthy lifestyle, individuals can potentially add years to their lives and counteract the effects of genetic predispositions toward shorter lifespans. It’s never too late to make positive changes for a longer, healthier life.
