Extend Lifespan and Health Span

Posted on by

Lifespan is the total length of a person’s life. Health span is the period of a person’s life during which they are generally healthy and free of serious or chronic illness. 

Recent scientific research suggests that aging might not be as inevitable as we once thought.

The aim of aging research is to extend both lifespan and health span. Lifespan refers to the total number of years a person lives, while health span focuses on the number of those years spent in good health, free from chronic diseases and disabilities.

Studies in the fields of genetics, cellular biology, and biochemistry have shown that the aging process can be influenced and potentially slowed down.

For example, researchers have discovered that certain genes and cellular pathways, such as those involving telomeres and sirtuins, play crucial roles in the aging process.

Aging in people results from the gradual accumulation of defects and damage to the molecules and cells that make up our bodies. However, our bodies have built-in mechanisms for repairing this damage. But even these repair mechanisms wear out over time. Eventually, enough damage accumulates to affect the function of whole organs and systems.

Telomeres, which are protective caps at the ends of chromosomes, tend to shorten as cells divide, leading to aging and cell death. However, some studies have shown that it might be possible to extend telomere length and improve cell longevity.

Additionally, lifestyle factors such as diet, exercise, and stress management have been shown to significantly impact the aging process.

Practices like calorie restriction and intermittent fasting have been linked to increased lifespan in various organisms.

Mindset Matters: Aging

Posted on by

Thinking Positively About Aging Extends Life. Positive self-perceptions about aging can prolong life expectancy.

Thinking positively about aging and getting older extends one’s life by seven-and-one half years. This is more than the longevity gained from low blood pressure or low cholesterol or by maintaining a healthy weight, abstaining from smoking and exercising regularly, a study by Yale University researchers have found.

“We found that those individuals who reported more positive self perceptions of aging demonstrated significantly longer survival than those who reported more negative self perceptions of aging,” said Becca Levy, assistant professor in the Yale University Department of Epidemiology and Public Health.

Researchers found that those respondents with more positive views on aging live longer, even after taking into account factors such as age, gender, socioeconomic status, functional health, self-reported health and loneliness.

“We found that the median survival of those in the more positive self perceptions of aging group was 7.6 years longer than those in the more negative aging self stereotype group,” the authors said.

The effects of positive attitudes about aging had a greater impact on longevity than low blood pressure and cholesterol, each of which is associated with a longer life span of about four years.

Positive attitudes about aging also had a greater impact on longevity than lower body mass index, not smoking and regular exercise – each of which extends life by one to three years.

“Our study carries two messages,” the authors said. “The discouraging one is that negative self perceptions can diminish life expectancy; the encouraging one is that positive self-perceptions can prolong life expectancy.”
