A new study, executed by Saint Luke’s Health Center in Kansas City, suggests that people playing tennis regularly could live an average 9.7 years longer than those who don’t exercise at all. In addition, badminton players could live 6.2 years and football players almost 5 years longer.
For the study, a team of researchers analyzed data from 8,577 people from the Copenhagen City Heart Study which began in 1975 and included adults whose age was from 20 to 93. The participants were followed for 25 years.
Study author James O’Keefe explains: “We know from other research that social support provides stress mitigation, so being with other people, playing and interacting with them, as you do when you play games that require a partner or a team, probably has unique psychological and physiological effects. Raising your heart rate is important, but it looks like connecting with other people is, too.”
A new study, executed by researchers from the University of Texas at Austin, US, finds that air pollution shortens life expectancy on the global level by up to two years and the situation worsens every year.
For the study, a team of the researchers looked at tiny PM2.5 particles that come from such sources as power plants, exhaust systems, airplanes, forest fires, and dust storms. These particles, due to their small size, stay in the air longer than the heavy ones and get deep into the lungs.
Dr. Joshua Apte, an assistant professor in the department of population health at the University of Texas at Austin, says: “The overall impact of air pollution is big and what we’re doing is putting the health benefits of addressing air pollution into context. For example, it could lead to a life expectancy that’s equivalent to or greater than curing certain import cancers like lung cancer and breast cancer.”
Experts have found that the length of telomeres in the chromosomes can set the duration of a person’s life. And besides – to determine a woman’s ability to have children later in life.
A telomeres are the end portions of chromosomes. They protect vital DNA during its doubling, preventing loss of nucleic chains.
The older a person becomes, the length of telomeres decreases. According to scientists, this pattern can help lengthen life.
It is noted that experts the study is based on the data of Long Life Family Study, according to which, the chances of a long life is greater in those women who have given birth to their last child after 33 years than those who had up to 29 years.
The researchers found that women who gave birth to their last child after 33 years, had a longer chromosomal telomere length. Experts also believe that telomeres may also be indicators of health, and a chance to slow aging.
