HEALTH

PEOPLE WITH A SENSE OF PURPOSE LIVE LONGER,

STUDY SUGGESTS

BY KASHMIRA GANDER ON 5/24/19 AT 11:10 AM EDT

People who have a sense of purpose in life appear to live longer, according to the  latest research linking this outlook to a person’s quality of life and to better physical and mental health. 

The authors of the study published in the journal JAMA Network Open  looked at data collected from 6,985 adults who were signed up to the Health and Retirement Study on people ages 50 and above in the US. The team looked at a group who completed a questionnaire in 2006 about their purpose in life, and used it to come up with a score. On average, the participants were 68.6 years old. Next, the scientists looked at causes of death in the group between 2006 and 2010. Variables included their demographic, marital status, race  and education level. Lifestyle choices like smoking and drinking were also noted. Purpose was defined by the authors as a selforganizing life aim that stimulates goals,  promotes healthy behaviors and gives meaning to life.

The data revealed that the stronger the participants felt they had a purpose in life, the lower their risk of dying. This result remained even when the scientists adjusted their calculations for factors that could affect their score, such as a participants’ sociodemographic status and their health.

But scientists don’t know why there seems to be a link between purposefulness and the length of life. One explanation is that the attitude and overall wellbeing could prevent genes linked with inflammation from being expressed in the body. Meanwhile, lacking a purpose could dampen a person’s motivation to be healthy and active, the authors suggested.

Andrew Oswald, a professor of economics and behavioral science at the University of Warwick, in the U.K., who studies human happiness, told Newsweek: “It is as though the mind and body can draw on a pool of immune responses, and a healthy mind allows the body more immune response, in some way that we simply do not understand in 2019. Remarkably, a number of studies seem to show that happy people and people with a sense of purpose live longer.”

Is alkaline water really better for you?

    Despite the claims, there’s no evidence that water marketed as alkaline is better for your health than tap water. “It’s all about marketing,” said Tanis Fenton, a registered dietitian and epidemiologist at Cumming School of Medicine at the University of Calgary. “There is no science to back it up.”

    The pH scale indicates whether a liquid is more acidic (lower pH) or alkaline (higher pH). Pure water has a neutral pH of 7, while tap water has some natural variation depending on its mineral content. Most bottled waters are slightly acidic, and sodas and juices are even more so. Bottled waters marketed as being alkaline typically claim to have a pH between 8 and 10. Some are from springs or artesian wells and are naturally alkaline because of dissolved minerals. Others are made with an ionizing process, and water ionizing machines are also marketed for home use.

    Alkaline water companies make vague claims that it will “energize” and “detoxify” the body and lead to “superior hydration.” And some claim that ionized water can prevent everything from headaches to cancer. Nevertheless, there’s no evidence that drinking water with a higher pH can change the pH of your body, or even that this outcome would provide benefits. Blood is tightly regulated at around pH 7.4, while the stomach, which secretes hydrochloric acid to digest proteins and kill food-borne pathogens, is very acidic, with a pH of 1.5 to 3.5. If you drink water that is slightly alkaline, Dr. Fenton said, the hydrochloric acid in the stomach quickly neutralizes it before it’s absorbed into the blood.

    Several small studies funded by companies that sell alkaline water suggest that it could improve hydration in athletes, but any potential benefits were modest, and an easier way to improve hydration is just to drink more water. And a 2016 review of research by Dr. Fenton and a colleague found no evidence that alkaline water or an alkaline diet could treat or prevent cancer.

    A study published last year found that adopting a plantbased diet and drinking alkaline water worked as well as medications to alleviate the symptoms of laryngopharyngeal reflux, a severe form of acid reflux in which stomach acid travels all the way up to the throat. “I think that it can be a helpful tool for patients to help with their symptoms while they’re transitioning to a more plant-based diet,” said Dr. Craig Zalvan, the study’s lead author and a laryngologist at Phelps Hospital in Sleepy Hollow, N.Y. But he believes that most of the improvement in his patients comes from dietary changes rather than alkaline water. Once symptoms improve, he says there’s no need to keep drinking alkaline water.
