Health: ‘Stress Exercise’ That Increases Longevity

Daniela Hernandez | WSJ (September 14, 2023) – Research shows that moderate amounts of physical stress can help your body stay healthier for longer.

That’s why longevity hacks, like intermittent fasting and ice baths, are blowing up on social media. I put myself through a strenuous 10-day workout plan to learn why and how the most active form of stress–exercise–is actually your best bet for a longer, healthier life.

Healthy Aging: ‘Outlive – The Science And Art Of Longevity’ By Peter Attia

Trained as an oncological surgeon, Attia became interested in longevity because he saw that the “Four Horsemen” worked against it: diabetes, heart disease, cancer, and Alzheimer’s disease. All play a role in an unhealthy system, and all interrelate.

A data- and anecdote-rich invitation to live better, and perhaps a little longer, by making scientifically smart choices.

If you have Type 2 diabetes, then your chances of developing heart disease, cancer, and neurological disorders increases, and if your goal is to live well in old age, then it behooves you to change your ways in order to keep your insulin reception levels in the clear. How to do so?

Health: Regular Exercise Prevents Heart Disease

 Frequent exercise is robustly associated with a decrease in cardiovascular mortality as well as the risk of developing cardiovascular disease. Physically active individuals have lower blood pressure, higher insulin sensitivity, and a more favorable plasma lipoprotein profile. Animal models of exercise show that repeated physical activity suppresses atherogenesis and increases the availability of vasodilatory mediators such as nitric oxide.

Exercise has also been found to have beneficial effects on the heart. Acutely, exercise increases cardiac output and blood pressure, but individuals adapted to exercise show lower resting heart rate and cardiac hypertrophy.

Health: American Heart Association Updates Its ‘Optimal Checklist’ (2022)

October 2022 – The American Heart Association (AHA) recently revised its checklist for achieving optimal heart health, introducing its new Life’s Essential 8. The list replaces the AHA’s decade-old Life’s Simple 7.

Sleep health is the new addition to the cardiovascular health scoring tool, which now advises that adults get seven to nine hours per night. The organization updated four of the categories:

  • Diet: More emphasis was given to following heart-healthy diets like the DASH and Mediterranean.
  • Nicotine exposure: Secondhand smoke and vaping were added as risk factors.
  • Blood lipids: People now can get a non-fasting blood sample that measures total, HDL, and non-HDL cholesterol. Non-HDL cholesterol can provide similar risk information as LDL cholesterol.
  • Blood sugar: Measurements now include hemoglobin A1c, a key component to assessing type 2 diabetes risk.
  • Three categories were unchanged:
  • Physical activity: The optimal weekly level is at least 150 minutes of moderate activity or 75 minutes of vigorous activity.
  • Body mass index (BMI): A BMI of 18.5 to 24.9 is ideal for heart health.
  • Blood pressure: Levels less than 120/80 millimeters of mercury (mm Hg) remain optimal. Stage 1 hypertension is 130 to 139 mm Hg for systolic pressure (the first number) or 80 to 89 mm Hg for diastolic pressure (the second number).
  • You can calculate your heart health score at mlc.heart.org. The guidelines were published online June 29, 2022, by Circulation.

Cardiometabolic Health: 93% Of U.S. Adults Fail Test

Less than 7% of the U.S. adult population has good cardiometabolic health, a devastating health crisis requiring urgent action, according to research led by a team from the Friedman School of Nutrition Science and Policy at Tufts University in a pioneering perspective on cardiometabolic health trends and disparities published in the July 12 issue of the Journal of the American College of Cardiology. Their team also included researchers from Tufts Medical Center.

Researchers evaluated Americans across five components of health: levels of blood pressure, blood sugar, blood cholesterol, adiposity (overweight and obesity), and presence or absence of cardiovascular disease (heart attack, stroke, etc.). They found that only 6.8 percent of U.S. adults had optimal levels of all five components as of 2017-2018.

Aging: The Importance Of Cardiovascular Exercise

Research: ‘The Science Of Healthy Aging’ (Scripps)

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.

Summer 2021
  • 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.

Exercise: The Evolution Of Human Physical Activity

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species?

Herman Pontzer explores the evolution of human metabolism and its role in our evolution and health. From an evolutionary perspective, life is a game of turning energy into offspring. The strategies that species use to acquire energy, in the form of food, and allocate energy to the essential tasks of growth, maintenance, movement, and reproduction, are incredibly diverse and reflect the ecological pressures and opportunities encountered. There is a deep evolutionary history of the human metabolic strategy and our divergence from other apes.
