Exercise THIS Much to Live the LongestWe all know that regular daily exercise will make us stronger and healthier and potentially help us to live longer than if we were sedentary. But how much moderate exercise is the right amount to accrue those benefits? We now know the answer: 450 minutes a week. That translates to 90 minutes a day, five days a week or 65 minutes a day, seven days a week.
Various government and health organizations have long called for 150 minutes of moderate exercise per week. (That's 30 minutes a day, five days a week.) But researchers from the National Cancer Institute and Harvard University wanted to know if this was the least amount we should do, as in the minimum recommended dose, or the ideal amount, reports The New York Times. And is there an upper limit for safety? Could too much exercise be dangerous?
The study: The team analyzed data from six large, ongoing health surveys on 661,000 mostly middle-aged adults, specifically focusing on their exercise habits. The participants were classified into groups, ranging from those who did no formal exercise to those who exercised 25 hours or more each week, which is 10 times the recommended amount. The researchers then compared this exercise data with 14 years of death records within the six studies.
Now get out there and start walking!
The study findings were reported in the journal JAMA Internal Medicine.
