Scientists may have discovered the key to healthy aging.
It's called immune resilience, the ability to stay healthy and bounce back after infections like the flu. People with good immune resilience have a 15-year survival advantage over those whose resilience starts to falter, a new study suggests. This is particularly true throughout middle age, but by around 70 years old, everyone's body pretty much becomes less resilient.
"We have similar aging rates, but very different health outcomes, which is what you call healthspan," said study author Sunil K. Ahuja, MD, a professor at UT Health San Antonio and director of the Veterans Affairs Center for Personalized Medicine, South Texas Veterans Health Care System. "The principle of immune resilience is basically the idea that there are some people who have the power to live longer and they get sick less often."
Taking steps to improve your immune resilience during midlife – between ages 40 and 70 – could be crucial for living longer and healthier, the findings suggest.
