Physical activity in any form, whether it is walking, running, yoga or strength training…saves lives and improves healthspan and lifespan. Along with the food you eat, physical activity has a direct bearing on how well you will live as you grow older. The more active you are, not only do you live longer, you also live healthier with less cognitive loss and with better control over your blood pressure and blood sugar. You can also offset the ill-effects of poor sleep if you are active and while physical activity does not directly help with weight loss, being active can significantly offset potential downsides of a higher BMI .
Just 4000 steps a day or walking at a reasonable pace for 30-45 minutes reduces your risk of death and disease compared to those who are sedentary, or if you were to be sedentary, and while any physical activity is better than none, it is good to add an additional layer of “fitness” to your physical activity. The fitter you are, the better is the health benefit across all ages, sexes and races.
