How to Turn Back the Clock on Aging, Say Experts
Turning back the biological clock is just the stuff of science fiction, right? Not quite. Recent studies have found that you can literally make yourself younger and increase your lifespan by making certain simple lifestyle choices. You can start doing some right now, right where you are. Read on to find out more—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had COVID.
Exercise This Way
A study recently published in the journal Cell Metabolism found that high-intensity interval training (HIIT) may reverse the aging of cells and muscles in older people. "Based on everything we know, there's no substitute for these exercise programs when it comes to delaying the aging process," says Sreekumaran Nair, MD, the study's lead author. "These things we are seeing cannot be done by any medicine."
He added: "We encourage everyone to exercise regularly, but the take-home message for aging adults that supervised high-intensity training is probably best, because, both metabolically and at the molecular level, it confers the most benefits."
And Play These Sports
Danish researchers recently found that regularly playing certain sports could extend your life expectancy by years—in one case, by nearly a decade. The top contributors to longevity: tennis (9.7 years), badminton (6.2 years), and soccer (4.7 years). The 25-year study, published in Mayo Clinic Proceedings, noted that all three sports are highly social—potentially reinforcing previous research that's found social isolation and loneliness are associated with chronic illness and a shorter lifespan.
This summer, researchers at Columbia University published a study that found gray hair really is caused by stress—and aging might be paused or even turned back. The scientists observed stressed-out people with graying hair; they found that hair regained its color when the source of stress was removed. "Our data add to a growing body of evidence demonstrating that human aging is not a linear, fixed biological process but may, at least in part, be halted or even temporarily reversed," said Martin Picard, Ph.D., associate professor of behavioral medicine.
Maintain Strong Relationships
And on that note: "People who are in happier, more satisfying relationships live longer," Dr. Robert Waldinger, director of the Harvard Study of Adult Development, told CNN recently. The study, which has been ongoing for nearly a century, tracks the effect of various life changes on longevity. One major finding: "The most important predictor of who was going to be a healthy, happy octogenarian was how satisfied they were in their relationships," said Waldinger. Experts say you should consider social interaction to be as important to your health as diet and exercise.
Brush and Floss
Might be time to reschedule that dentist's appointment you've been avoiding for two years. According to a study published in the journal BMJ Open, people with high levels of dental plaque are 80 percent more likely to die prematurely of cancer than those who have a small amount of plaque—even after adjusting for other major risk factors. The potential culprit: Bodywide inflammation, which can start in gums irritated by plaque. Cancer isn't the only potential danger—inflammation is so linked with the aging process that it's spurred the nickname "inflammaging."
