New research, including a study from the University of Sydney published in the journal *eClinicalMedicine*, suggests that even the tiniest changes to sleep, diet, and exercise habits can have significant benefits for overall health and longevity. For individuals with the least healthy habits, adding just five extra minutes of sleep per night, two minutes more of moderate-to-vigorous physical activity (like brisk walking), and half a serving of vegetables daily could potentially add an extra year to their life. This highlights that small, consistent behavioral adjustments can accumulate over time to make a meaningful difference. The findings are corroborated by several other studies. One analysis of nearly 60,000 people from the UK Biobank indicated that these small improvements, when combined, could lead to meaningful changes in lifespan. While minimal changes offer benefits, more substantial yet still manageable lifestyle changes can yield even greater results, potentially extending life by up to four years for combined improvements like 24 extra minutes of sleep, 3.7 extra minutes of exercise, and a 23-point increase in diet quality score. Other research suggests that adopting an optimal combination of these behaviors, such as 7-8 hours of sleep, over 40 minutes of moderate-to-vigorous activity, and a healthy diet, could be associated with living almost a decade longer. Beyond individual components, combining small improvements across multiple behaviors offers a more powerful and sustainable strategy for better health outcomes than focusing on larger changes in a single area. Furthermore, research suggests that adopting healthy habits, even if delayed until middle age (40s, 50s, or 60s), remains beneficial and can significantly prolong life expectancy, with some studies indicating gains of over 20 years for men and women who adopt a comprehensive set of healthy lifestyle factors. These factors include not just diet, sleep, and exercise, but also stress management, avoiding binge drinking, being free from opioid addiction, and having positive social relationships. The consensus among experts is that while significant overhauls are impactful, even minor, pragmatic adjustments can initiate a journey towards a longer, healthier life.
