If you feel that you can smoke, drink heavy and leave exercise in your 20 and 30s and still live a healthy life in old age, then think again.

A new long -term study has found that these habits can start harming your body and brain long before expectation, even at the age of 36.

The Peer-Ruid Study published in The Annals of Medicine tracked hundreds of people from the Finnish city of Jyavskila, born in 1959, in 1959, in 1959. Researchers found that those who used to smoke drank heavy, and rarely exercised, were poor mental and physical health until the age of 36, and the risks only deteriorated over time.

“Our findings show that the importance of quick addressing unhealthy behavior is shown. But the good news is that there is never a delay in making positive changes,” a health scientist Dr. Tia Keklenon said, who specializes in aging.

The study followed 326 people aged 27 and assured 206 of them at 36, 42, 50 and 61 years of age. Researchers analyzed their mental health through surveys on depression and psychological welfare, and measured physical health using blood pressure, cholesterol, waist size and other markers.

Participants were also asked to rate their own health, and were assessed for three risky behaviors: smoking, heavy alcohol, and exercising less than once a week.

Those who had all three habits were once seen to have a significant decline in health. He was at greater risk of diseases such as high levels of depression, poor self-rated health and diabetes and heart issues.

In fact, the metabolic risk score for such individuals increased by 1.49 points in years, a sharp spike.

The study found that the lack of exercise was most strongly associated with poor physical health, smoking had the worst effect on mental health, and heavy drinking affected both negatively.

Researchers stated that the study was related to observation, which means that it could not prove that bad habits directly cause poor health, although the link is strong. In some cases, poor mental health may have motivated people to drink or smoke, causing their health to worse.

He concluded that over time many unhealthy habits, such as smoking, drinking too much, and not exercising were associated with poor mental and physical health. It is important to prevent these habits at adulthood or moderate age to avoid prolonged health problems.

He also accepted the limits of the study, focusing on three behaviors and its old Western samples. Future research can expand to include diet and new lifestyle patterns.

Nevertheless, the message is clear: start the youth, but even if you are late, switching on healthy habits can still make a difference.
