A recent study published in BMJ Evidence-Based Medicine has shed light on the impact of genetics and lifestyle on life expectancy. The study, based on data from over 350,000 participants in the UK Biobank, found that genetics and lifestyle choices independently affect life expectancy. People with high genetic risks of a shorter life span have a 21% increased risk of premature death, while those with unhealthy lifestyles have a 78% increased chance of early death.
However, the study revealed that a healthy lifestyle can compensate for genetic risks and significantly extend the lifespan of individuals predisposed to shorter lives. Participants with a high genetic risk could reduce their risk by around 62% and increase life expectancy by approximately 5.22 years when they reach the age of 40.
The study emphasized the importance of maintaining healthy habits, such as not smoking, engaging in regular physical activity, getting adequate sleep, and following a healthy diet. These lifestyle factors were identified as key components that could offset genetic risks and promote longevity.
Experts in the field agree that education on healthy lifestyles should start from childhood to instill good habits early on. Additionally, public health policies should focus on promoting health education, encouraging preventive medical check-ups, and providing personalized health management to high genetic risk groups.
In conclusion, the study highlights the importance of a healthy lifestyle in overcoming genetic predispositions to shorter life spans. By adopting healthy habits, individuals can substantially improve their quality of life and maximize their life expectancy, regardless of genetic factors.
