New Delhi, Feb 4 (ANI): A new study has revealed that light jogging is very effective for longevity. The research explained that jogging from 1 to 2.4 hours per week was associated with the lowest mortality and the optimal frequency of jogging was no more than three times per week. Researchers said that the pace of the slow joggers corresponds to vigorous exercise and strenuous jogging corresponds to very vigorous exercise, so when it's performed for decades, this activity level could pose health risks, especially to the cardiovascular system. If anyone wants to decrease the risk of death and improve life expectancy, than jogging a few times a week at a moderate pace would be a good strategy, as doing it more might be harmful to the health.
