One minute of exercise correlates to five extra minutes of life (on average).

Moving your body every day is key to longevity

In an era of biohacking, where millionaires subject themselves to draconian routines and tests to de-age themselves, one study suggests a super simple key predictor of mortality: more than any other trait, how much subjects moved determined how long they'd live. Movement mattered even more than age in predicting overall life longevity. Researchers suggest this means we should all simply get outside a bit more. Read more about the study here.

The exercise sweet spot is shorter than you'd think—and longer workouts aren't generally better.

Recent global health estimates suggest that inactivity is a leading risk factor for death, contributing to 6% of deaths worldwide.

Exercise can change your genes without changing your DNA.

Optimal human functioning requires movement

There is now ample evidence to back the centuries-old hypothesis that exercise is critical to human health. This review article explores the latest discoveries in exercise science, including how exercise is intrinsic to maintaining our organ systems throughout life.

Exercise improves brain blood flow, stimulates neural growth, and more.

Health officials recommend at least 150 minutes of aerobic exercise per week and 2 sessions of resistance training, targeting each major muscle group.

Even brief physical activity can trigger the release of neurotransmitters that provide mental health boosts

A couple of minutes of light walking or stretching can increase feelings of energy and reduce fatigue, not just through the release of endorphins. Exercise can also provide self-regulation and improve task engagement and focus in those with certain mental health disorders, like ADHD.

Extending the worldwide lifespan by one healthy year is worth $38T

This econometric study attempts to estimate the economic value of increasing the global healthy lifespan by one year—and to answer the question of whether it is better to extend lifespans or slow the rate of healthy aging.

The eight habits that could add up to 24 years to your life

A study presented at the American Society for Nutrition's annual meeting revealed that adopting eight healthy lifestyle habits in middle age can significantly increase life expectancy. The habits include being physically active, avoiding opioid...

Just a 10-minute mental health break can yield benefits

The US CDC offers recommendations for alleviating stress in daily life. Short 10-minute breaks can significantly improve mental health, especially when used for activities like deep breathing, dancing, or writing down things you are grateful for. Building meaningful relationships, termed "social connectedness," can also alleviate stress and promote resilience.

The reason some people love exercise may be because of their microbiome

Certain gut microbes in mice trigger dopamine release and drive motivation to exercise more. Scientists are investigating whether humans carry similar microbial patterns that influence our natural inclination towards movement, exploring how unseen microbial ecosystems may shape mammalian fitness behavior and reinforce innate reward pathways.

Doctors are prescribing social activities—and seeing good results

Physicians, especially in the UK, are asking patients what they enjoy and then prescribing a consistent regimen of doing that type of activity to improve fitness and overall health, including community exercise classes, volunteering, and spending time in nature. This approach may provide better incentives to stick with an activity.

Exercise causes diet-independent changes in the gut microbiome.

Can fasting help you live longer?

Animal studies into the health benefits of calorie restrictions of 20%-40% suggest it extends life spans and reduces incidents of age-related diseases, including cancer. This article explores the research into fasting, calorie restriction, and longevity.

Adults need 2 days of muscle-strengthening activity weekly—yet most of us aren't doing that.

Can humans delay or reverse old age?

We're not sure yet. Researchers at the University of California San Francisco are studying why some conditions and behaviors, such as low-oxygen environments and exercise, benefit the aging process, hoping to reveal potential health applications. Some of this research focuses on klotho, a naturally occurring age-regulating hormone named after the Greek Fate Clotho. Animal studies on klotho brain injections found subjects had improved memory recall and age-related degeneration resistance.

Exercise helps make your arteries more elastic.

Each part of the human body experiences aging differently

With global average life expectancy cresting at 73 years, understanding how the body ages is imperative to effective medical treatment and maintaining a desired quality of life. This 13-minute video dives into how the body and its organs age "from head to toe."

Multiple new research paths may lead to slowing (or even reversing) aging

Aging has always been inevitable, but fasting, epigenetic reprogramming, and parabiosis seem to help people stay young. By studying centenarians, memory, and even the humble roundworm, scientists are looking for the genetic basis to live not just a long life, but a healthy one.

Health span: The number of years one is active and disease-free

As scientific advances continue to extend the average human lifespan, many are now turning their attention toward extending "health span." The ultimate goal would be to extend one's health span to match one's lifespan, which would necessitate a shift in focus toward the pursuit of healthy aging. (Some users may experience a paywall.)

Astronauts exercise on the International Space Station

Astronauts maintain bone, muscle, and cardiovascular health with physical activity. It's crucial that they make time to exercise for approximately two hours per day. This resource offers a behind-the-scenes look at how high-intensity workouts help prevent muscle atrophy, bone density loss, and aerobic decline during monthslong space missions.

Doctors shift focus from extending lifespan to lengthening health span

As scientific advances extend the average human lifespan, many are turning their attention toward extending "health span." Health span refers to the number of years one is active and disease-free. The ultimate goal is to extend one’s health span to match one’s lifespan.

Strength training appears to make for a healthier, youthful-looking brain.

Offering support to others linked to cognitive and physical health improvements

The Baltimore Experience Corps Trial, which was a large study evaluating the health benefits of volunteering among older adults, concluded that seniors spending about 15 hours weekly offering kids tutoring and mentoring was associated with improvements including better memory and increased mobility and strength.

Myokines are molecules that facilitate some of the benefits of exercise

When muscles contract, they release ‘hope molecules’ (myokines) such as IL-6 and irisin. These proteins then travel through the bloodstream to reduce inflammation, improve insulin sensitivity, and even support brain repair. This piece illustrates how movement triggers a systemic healing cascade throughout the human body.

Global life expectancy has more than doubled since the 1850s

The human species experienced a dramatic increase in expected lifespan over the past 150 years. Antibiotics, improved sanitation, and better worldwide food distribution are a few factors contributing to this rapid transformation.

World records are often broken later in the day—and scientists wonder if muscle clocks explain the difference.

Exercise releases chemicals that enhance cognitive function

Neurotransmitters like dopamine, serotonin, and norepinephrine, along with increased brain-derived neurotrophic factor levels, enhance a wide range of brain functions. New research demonstrates a direct link between movement and numerous cognitive benefits, including memory, learning, and stress resilience.

VO2 max measures the body's ability to use oxygen to produce energy

VO2 max is the maximum rate at which the body can use oxygen to aerobically produce energy—adenosine triphosphate—for use during intense exercise. Aerobic exercise increases VO2 max, counteracting age-related decline by increasing the body's capillary count and remodeling the heart's left ventricle, increasing the amount of blood it pumps.

Yoga can be beneficial for aging practitioners

Studies suggest that yoga can help alleviate several diseases associated with aging by lowering blood pressure, reducing blood fat levels, and combating obesity. It has also been shown to increase telomerase activity, which helps slow cell aging.
