Does Healthy Lifestyle Affect Life Expectancy?
A major research carried out by Harvard specialists found that developing five lifestyle-challenging habits and changing your lifestyle according to them can bring an adult as much as 12-14 extra years of lifespan. While all these habits have been being promoted for quite a long time, it is the first study of its kind to evaluate the impact of lifestyle choices on life expectancy in US citizens.

Healthy lifestyle aspects
A team of scientists from Harvard University surveyed 123,000 adults from the US to find out whether changing their lifestyle would result in any increase in lifespan. They compared the data provided by the participants themselves and their medical history. The aim was to determine whether 5 habits characteristic of a healthy lifestyle would benefit them to a significant extent. The habits were as follows:- Never smoking.
- Moderate drinking.
- Sticking to a healthy eating pattern.
- Weight management.
- Exercising daily.
Astonishing results
The follow-up lasted 34 years. During the period, the scientists documented 42,167 cases of death. Having compared calculations of life expectancy for those who followed the rules and those who did not, the scientist came to a conclusion that the participants who preferred a healthy lifestyle at age 50 had higher life expectancy figures. The dramatic increase was from 26 to 38 years of life expectancy for men (which is an increase by around 12 extra years), and from 29 to 43 years in the case of ladies (which means 14 extra years were added). The powerful effect came as a surprise, as the scientists had not expected the difference to turn out to be so striking. The study findings suggest that the participants who followed the rules (regardless of sex) had their risk of developing a heart disease reduced by 82%, and the likelihood of dying of cancer was reduced by around 65%.A lot to be done
Despite spending more on services related to healthcare than many other developed countries, the US still takes 31st place in life expectancy rankings. In 2015, the figures were 81.6 and 76.9 for ladies and men respectively. Poor lifestyle choices appear to be a major contributor to premature death risk, as only 8% of American citizens stick to all the five rules that were taken into account in the study. Most western countries also fail to follow these rules, and both adults and children do not exercise enough and eat foods that are not healthy, so the study results could be translated to other countries as well.The message here is that you can change your life regardless of your age: even if you are not a youngster anymore, you can follow these 5 rules and have a healthier life. It may take an iron will to stop smoking or give up the habit of munching on chips (as well as other bad habits and traits), but these healthy habits can make you feel better – just give it a try and challenge yourself with becoming a better person!
