Aging has long been considered a gradual process, but new research challenges that belief, suggesting that people experience two distinct bursts of rapid aging—one in their mid-40s and another in their early 60s. A study published on nature.com monitored the molecular markers of 108 people aged between 25 and 75. The findings revealed that instead of aging slowly and consistently, the body undergoes significant changes during these key periods, resulting in faster aging.
Professor Michael Snyder, a geneticist and senior author of the study, highlighted that dramatic changes occur during these phases, altering cellular repair mechanisms and increasing inflammation and oxidative stress. According to Dr. Balakrishna GK, head of internal medicine at Gleneagles BGS Hospital, the accumulation of cellular damage and reduced regenerative capacity in the early 60s further accelerates the aging process, contributing to visible signs such as wrinkles, joint discomfort, and sagging skin.
While the study focused on American participants, Indian experts like Dr. Prashant Saxena of Fortis Memorial Research Institute and Dr. Vishakha Shivdasani, a physician specializing in longevity, agree that midlife and later-life transitions are globally relevant. They emphasize that lifestyle changes in the mid-40s, such as increased alcohol consumption, poor sleep, and higher stress, can accelerate aging. Dr. Shivdasani notes that Indians, particularly prone to diabetes and cardiovascular disease, may experience even earlier signs of aging compared to those in the West.
By age 60, the risk of chronic health issues like cardiovascular disease rises, and immune regulation weakens. These biological shifts can be compounded by psychological factors, such as stress related to career transitions or retirement, which may intensify the perception and effects of aging. Experts warn that people in their mid-40s might experience a decline in metabolic rate, increased joint pain, and more visible skin aging. By the early 60s, more serious issues like cognitive decline, reduced bone density, and mobility challenges become prevalent.
While aging cannot be stopped, experts suggest lifestyle changes to mitigate its impact. Regular physical activity, a balanced diet rich in antioxidants, strength training to maintain muscle mass, and managing stress are all crucial. Preventive healthcare measures like regular screenings and check-ups become essential as one approaches their 60s. Fitness expert Kushal Pal Singh also emphasizes the importance of functional training to improve balance and mobility, while focusing on maintaining proper posture and preserving muscle mass. Additionally, proper sleep is critical to boosting immunity and preventing accelerated aging caused by inflammation.
