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

A meta-analysis concluded that resistance training for about 60 minutes per week provided the best health benefit—decreasing the likelihood of death for individuals within a specific timeframe around 27%.

Health officials recommend at least 150 minutes of aerobic exercise per week

This official guideline from the CDC defines the baseline recommendation for healthy adult activity. These recommendations also emphasize that any movement is better than no movement, and that even short bursts of activity spread throughout the week benefit the mind and body.

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

Exercise has dramatic effects on human biology, including reducing some of the long-term harms associated with chronic stress. Its effects are also pronounced in the brain, including improved memory retention, sleep, cognitive functioning, and more.

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. (Some users may experience a paywall.)

Estimates suggest inactivity contributes to 6% of deaths worldwide

The World Health Organization identifies physical inactivity as the fourth leading modifiable risk factor for global mortality, just behind hypertension, tobacco use, and high blood glucose. Latest estimates are that inactivity contributes to 6% of deaths and significantly increases the burden of chronic diseases like heart disease, diabetes, and cancer.

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.

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.

Astronauts exercise on the International Space Station

Astronauts maintain bone, muscle, and cardiovascular health with physical activity. It's crucial astronauts 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 months-long space missions.

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.

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.

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

For reasons that are still not entirely clear, on average, people tend to lift more weight and achieve other exercise feats later in the day. Theories to explain this discrepancy include muscle clocks are at peak performance in the afternoon and that there's morning-to-afternoon variation in core body temperature, hormones, and neural activity.

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.

Studies suggest when you sleep is as important as how much you get, and syncing with your circadian rhythms may lead to less fatigue and improved long-term health outcomes

The 15-minute city lets residents meet their daily needs within 15 minutes on foot

Many cities have been designed with inefficient layouts that waste time and lower the quality of life of those who live there. In the 15-minute city, essential services—including work, food, education, and health—should all be located within a short walk or bike ride from where people live.

Adults may lose roughly 3% of their muscle mass each decade after 30

That muscle loss, formally referred to as sarcopenia [saar-ko-pee-nee-uh], averages 3% to 5%, depending on physical activity. These losses can progress with age, but resistance training helps combat some of this natural degradation.
