Secret Recipe for Longer Life

Recipe for Longevity: No Smoking, and Lots of Friends – Of all the news I’ve been reading these days, this one’s the best so far. It’s possible. And it’s doable.

Tobacco use kills 5.4 million people a year - an average of one person every six seconds - and accounts for one in 10 adult deaths worldwide. –WHO Smoking also bolsters the process for six of the eight leading causes of death, including heart disease. On the other hand, researchers found that of 300,000 men and women across the developed world, an average of 50% higher death risk threatens people with poor social connections

With these two aspects reversed, longevity change will become apparent. How true? According to the research, the longevity boost is as huge as the death rate caused by smoking. And although, there are no gathered proofs yet, physiological mechanisms are believed to have a link between feelings of loneliness, for instance, to blood pressure and resting heart rate as biological markers.

When one is happy with his or social life and no toxic tobacco substances jeopardize the vital organs, that person is most likely to live longer. As recent lab studies suggest, a stressful situation will increase blood pressure and heart rate lesser when people are accompanied by a person or group of individuals who are close to them. Support from other people also show good effect to neurological aspect of a person. Brain imaging shows activity in the anterior cingulated cortex, the region that activates in times of stress, is calmed when someone close is around. A child who is faced with stress but is accompanied by the mother, has increased levels of oxytocin, the neurotransmitter believed to dampen stress. Better social life also has good effect to the immune system as shown by Sheldon Cohen’s research. The stress hormones catecholamines and glucocorticoids are believed to also have effect on immune response.

While people can build friendship with strangers, relationships that natural occur would best help, just as Julianne Holt-Lunstad, lead author of the study said. This can be true, as in many cases, parents, siblings and the rest of the family are the ones usually around. Classmates, colleagues, and neighbors, whom a person spends more time with, must become their friends as well. People should also build friendship even with those people whom they trust, like doctors in lab coats, as well as lawyers. They are the people whom most can easily find and turn to when bad things happen.
