Longevity is a topic that has fascinated humans for centuries. Many factors contribute to our overall health and lifespan, but some are more important than others. A recent study published in the medical journal BMJ compared the impact of genes and lifestyle on longevity for the first time, shedding light on which lifestyle choices matter most.
The study tracked the health of 353,742 adults of European descent from 2006 to 2010 through 2021 to determine whether genes or lifestyle had a greater influence on longevity. Participants were classified based on their genetic tendencies and healthy lifestyle behaviors such as not smoking, exercising regularly, eating a balanced diet, getting enough sleep, maintaining a fit body shape, and consuming alcohol in moderation.
The results were clear: individuals with unhealthy lifestyles had a 78% higher risk of premature death compared to those living healthy lives, regardless of their genetic predisposition. People with genes related to shorter lifespans were still 21% more likely to die early, but adopting a healthy lifestyle reduced this risk by 62%. In fact, individuals with the short lifespan gene who followed a healthy lifestyle could live 5.22 years longer than those who did not.
This study highlights the importance of maintaining a healthy lifestyle in promoting longevity. While genetics play a role in determining our overall health and lifespan, it’s clear that our daily choices can make all the difference. By prioritizing good sleep, regular exercise, a balanced diet, and avoiding smoking (and other harmful habits), we can significantly improve our chances of living longer and enjoying good health throughout our lives.
