#Moderateexercise

A major new study has shaken up our understanding of how physical activity protects our brains, revealing that “more isn’t always better” when it comes to exercise and healthy aging. Researchers now say that moderate—not excessive—levels of physical activity may be the secret to maintaining a youthful brain, challenging decades of advice that simply “more exercise” leads to stronger minds for life.

Published in the peer-reviewed journal Health Data Science and led by Associate Professor of Public Health at Hangzhou Normal University in partnership with Tianjin University of Traditional Chinese Medicine and Tianjin Medical University, this ground-breaking research involved a robust analysis of data from 16,972 participants in the UK Biobank. Using state-of-the-art machine learning and MRI scans, the scientists set out to answer a question that affects millions of Thais: could the right amount of daily movement slow down our brain’s aging—without going overboard?

Moderation, a core Thai value rooted in the Buddhist concept of the middle path, now links to sharper thinking in aging minds. A large new study shows that moderate physical activity, not intense training, offers the best protection against cognitive decline. For Thai families, this finding resonates with everyday wellness practices and could reshape how communities pursue brain health.

Researchers tracked nearly 17,000 participants, measuring movement with wrist devices over a week and analyzing brain imaging data to estimate brain age. Published in Health Data Science, the study challenges the notion that more exercise always equals better brain health. Instead, a U-shaped curve emerged: too little activity speeds aging, while excessive exercise offers no extra benefit and may even harm cognition.

A new study from China suggests that more exercise isn’t always better for the brain. Both too little and too much physical activity may accelerate brain aging, challenging the belief that higher activity always sharpens cognition. The researchers describe a “Goldilocks zone” where moderation yields the best brain health.

The Health Data Science study analyzed nearly 17,000 adults to reveal a U-shaped relationship between activity and brain aging. Wrist accelerometers tracked movement while advanced brain imaging estimated each person’s brain age. Those in the middle range of activity showed the strongest brain health, while the least and most active groups exhibited signs of accelerated aging. The study’s average weekly activity levels were roughly 34 hours of light activity, 7.7 hours of moderate activity, and about 20 minutes of vigorous activity. Participants performing far more strenuous exercise were labeled “excessive exercisers,” while those with very low activity were classified as sedentary.

Zone 2 training, once the domain of elite endurance athletes, is now gaining traction with health-conscious beginners and seasoned gym-goers alike. New research and expert guidance highlight its sustainable fat-burning benefits and cardiovascular advantages, without the harsh demands of high-intensity workouts. For urban Thais facing limited time, rising obesity, and pandemic fatigue, Zone 2 offers an accessible route to better health.

Unlike traditional HIIT, Zone 2 keeps your heart rate at roughly 60–70% of maximum. The maximum is roughly 220 minus your age. In this “fat-burning zone,” you can speak in sentences without gasping, indicating a moderate effort that can be sustained for longer periods. In Bangkok’s Lumpini Park, around Rattanakosin Island, or even while tending the garden, easy, steady activity keeps you in this beneficial zone. For city dwellers who need practical fitness, this is welcome news.

Zone 2 training—once a niche exercise concept reserved for elite endurance athletes—has taken the global fitness scene by storm, attracting both health-conscious beginners and seasoned gym-goers. As new research and expert opinions pile up, this moderate-intensity approach is being celebrated for its sustainable fat-burning benefits and overall cardiovascular health, all without the demands of punishing high-intensity sessions. For Thai readers navigating the challenges of urban living, rising obesity rates, and pandemic fatigue, Zone 2 offers a practical, accessible path to improved wellbeing.

A new fitness trend is gaining momentum worldwide — and it’s not about pushing your body to its limits. Zone 2 training, dubbed the “fat-burning zone,” is making headlines for offering the promise of significant health and fat loss benefits without the grueling exhaustion of high-intensity workouts. As scientific research and health experts validate its effectiveness, Zone 2 training could reshape how Thais approach exercise, weight management, and disease prevention in everyday life.

A new fitness trend is winning fans worldwide—not by pushing to the limit, but by staying in a comfortable, sustainable pace. Zone 2 training, long dubbed the “fat-burning zone,” is gaining traction for delivering health and weight-management benefits without exhausting workouts. For Thai readers, this approach could reshape daily exercise, disease prevention, and long-term wellness.

Zone 2 refers to aerobic exercise kept at roughly 60–70% of a person’s maximum heart rate. This level allows fat to become the primary energy source, rather than carbohydrates or protein. Activities like brisk walking, casual cycling, or moderate swimming fit this zone. It’s the kind of effort where conversation remains easy, enabling longer, more sustainable sessions.

A growing body of research and expert analysis warns that High-Intensity Interval Training (HIIT)—long promoted as the ultimate quick and efficient fitness solution—may pose serious health risks for adults over 50. As Thailand’s population ages, understanding which exercises truly benefit longevity and wellbeing is critical for turning back the clock not just on the surface, but deep within our bodies.

The concern over HIIT and similar high-intensity workouts lies in how older bodies respond to extreme exercise. According to the recent article published by Journee Mondiale (journee-mondiale.com), fitness professionals and medical researchers no longer consider HIIT universally safe for the over-50 crowd. The main culprit appears to be the body’s stress response: HIIT can trigger a surge in cortisol, the so-called ‘stress hormone.’ For adults over 50—especially women undergoing menopause—this cortisol spike may amplify hormonal imbalances, contribute to sleep issues, spark chronic inflammation, and promote fat accumulation around the waist, all maladies already associated with aging. Sports medicine specialists note that the long-term elevation of cortisol could counteract the cardiovascular benefits of exercise, raising the risk of heart problems.

A growing body of research warns that high-intensity interval training (HIIT) may not be the universal best choice for adults over 50. As Thailand’s population ages, it’s essential to identify exercises that truly support longevity and well-being for longer, healthier lives.

Experts say the body’s response to extreme effort changes with age. A recent analysis suggests HIIT is not universally safe for those over 50. The primary concern is the stress response: HIIT can trigger a spike in cortisol, the body’s stress hormone. For people approaching or beyond menopause, this cortisol surge can worsen hormonal imbalances, disrupt sleep, promote chronic inflammation, and encourage fat accumulation around the waist. Over time, sustained cortisol elevation may blunt cardiovascular benefits and raise heart risk.
