The Science of Healthy Aging: Six Keys to a Long, Healthy Life

Although growing older comes with a number of major life changes, science can help inform the things we do in the here in and now to forestall the most serious features of the aging self, promoting healthspan and not just lifespan.
Build Muscle
Muscle mass is one the best predictors of health and longevity. Muscle tissue is known to release its own chemicals called myokines, which can have benefits that span cognition, immunity and anti-cancer activity. By performing regular, resistance-based exercise that prioritizes strength, we can delay the loss of bone density and risk of physical injuries.
Vitamin D
Commonly known as the sunshine vitamin, vitamin D is in fact a critical hormone that helps maintain healthy bones, boost our immune system and improve our cardiovascular function. With age, the production of vitamin D in the skin can become less efficient, so if we don’t spend enough time outdoors, our risk of vitamin D deficiency may increase.
Neurodegenerative Diseases
One of the most unsettling aspects of aging is the potential for neurodegenerative disease. These conditions are increasingly prevalent in those with diabetes, suggesting that the brain’s blood flow and energy supply may be compromised. Research indicates that regular physical exercise, a healthy whole foods diet and staying intellectually active could at least slow the rate of decline.
Mindfulness
As we get older, major arteries can become thicker and less flexible, leading to increased blood pressure and undue strain on the heart. A regular mindfulness practice such as yoga or meditation has been shown to stem the release of stress hormones like cortisol and adrenaline. By freeing us from this “fight-or-flight” state, this habit can improve blood flow and reduce the risk of heart attack and stroke.
Stay Social
As social animals, maintaining a strong sense of community and close personal relationships into old age are underestimated contributors to longevity. While social isolation in seniors can result in significant physical and mental decline, research suggests that close loved ones offer important emotional support and behavioral modifications that can overcome periods of high stress.
Metabolism
“My metabolism is slowing down!” That’s what we often hear, as the aging body becomes less effective at using energy, placing us at risk of obesity and type 2 diabetes. By maintaining our muscle mass and reducing sugar consumption, we can support hormonal health, preserve our metabolism and keep our vitality into those advanced years.
As scientists continue to find ways to extend our lives, paying attention to these keys to healthy aging can help increase the quality of those extra years.
