An article published in The Indian Express on January 15, 2026, features a gastroenterologist, Dr. Saurabh Sethi, who refers to walking as the 'easiest longevity cheat code science has ever discovered'. This engaging statement, while somewhat sensationalized, accurately reflects the profound and scientifically backed health benefits of regular walking. Numerous studies corroborate that consistent physical activity, particularly walking, is a powerful tool for improving healthspan and increasing life expectancy. Research involving nearly 80,000 people over seven years indicated that individuals who walked between 7,000 and 10,000 steps daily experienced significantly lower risks of heart disease, cancer, dementia, and stroke, leading to a longer life expectancy. Furthermore, studies have shown that every additional 2,000 steps per day can lower the risk of early death by approximately 10%. Dr. Rahul Mathur, an internal medicine expert, reinforces that walking is the most powerful and simplest form of exercise, positively impacting multiple bodily systems. It helps improve blood pressure, regulate blood sugar, reduce harmful LDL cholesterol, strengthen bones, and boost mood by releasing endorphins. For middle-aged and older adults, regular walking is associated with a 30-50% lower risk of heart disease, stroke, type-2 diabetes, and cognitive decline. Brisk walking is particularly beneficial, enhancing blood flow to the hippocampus, which aids memory and reduces the risk of dementia. Even short, consistent walks, such as 20-30 minutes daily or 10-minute intervals, yield measurable health gains, with consistency being more crucial than speed, although interval walking can offer amplified benefits. Walking is highly accessible, low-impact, requires minimal equipment, and can be easily incorporated into daily routines, making it a universal strategy for promoting healthy aging across all populations.
