According to a new study from Harvard University, there is a range of healthy lifestyle options, such as maintaining a healthy weight, not smoking, and exercising regularly, which can greatly increase the number of years the human body survives a disease, according to what is published. “Medical News Today”, citing the British Medical Journal BMJ.
In the details, it is on average than humans currently live longer, but with age, most of them live with chronic diseases, such as heart disease, diabetes, and cancer.
The longer a person’s life, the greater the risk of developing chronic diseases.

However, the research team firmly demonstrated that lifestyle factors can make a significant difference in the risk of developing the disease with age in general. These factors include physical activity, smoking, diet, and weight.
“The studies show that smoking, inactivity, and poor diet quality contribute to up to 60% of premature deaths and a loss of 7.4 to 17.9 years in life expectancy,” the researchers explain.
Free from diseases
Although this is well known, there has been little research showing that a combination of lifestyle factors influences the length of time an individual becomes free of diseases.
To answer this question, the researchers obtained data from the results of two scientific studies on the health of nurses, which included information from 73,196 nurses, and a follow-up study of health professionals, and included 38,366 male professionals.
Lifestyle and health
The scientists calculated the lifestyle score from 0-5 for each participant, and 4 low-risk lifestyle factors were evaluated in terms of healthy weight, non-smoking, exercising for at least 30 minutes per day, and a good quality diet.
Genetic component, age, and race
The researchers followed the information and data of the participants over many years and recorded diagnoses and deaths from cancer, type 2 diabetes, and cardiovascular disease.
As part of their analyzes, they extracted a range of factors, including family medical history, age, and race.
For women under 50 years old
The researchers found that women who have not yet reached the age of 50 and commit to avoiding some of the four factors of a low-risk lifestyle can expect to live without cancer, diabetes and heart disease for another 24 years.
Those who avoid all four risk factors can expect an additional 34 years free of disease.
Men 50 years old
Also, men who reach the age of 50, and who have not made the mistake of following some high-risk lifestyles, can live an additional 24 years free of chronic diseases.
Men who are 50 years old, and who have successfully adhered to all of the low-risk lifestyle factors, can live an additional 31-year period free of chronic diseases.
The dangers of smoking and obesity
Men who smoke more than 15 cigarettes a day, and anyone who is obese, has the lowest rate of disease-free life expectancy after 50 years. Researchers summarize it as follows:
Scientists also found that men and women with 3 or 4 low-risk lifestyle factors, who received a diagnosis of cancer, cardiovascular disease, or type 2 diabetes, lived longer than individuals with the same diagnoses, and those who did not abstain from the risk factors On health.
“A healthy lifestyle not only reduces the risk of cancer, cardiovascular disease, and type 2 diabetes but also improves survival after being diagnosed,” the researchers say.
The researchers note the need to know that the results of the study are based on observation, so a causal relationship cannot be concluded, and the limitation of low-risk lifestyle factors may also involve some inevitable measurement errors.
