Research shows that increasing the intensity of exercise reduces risk of death, even just brisk walking and using stairs can be effective
Most people know that to live longer, they should exercise regularly. A new study has found that the higher the intensity of exercise, not just the amount of exercise, the lower the risk of death.

Boosting Exercise Intensity Reduces Mortality Risk, Study Suggests : ScienceAlert

A research team led by researchers from the University of Basel in Switzerland used data from the National Health and Nutrition Examination Survey (NHANES) , a nationwide survey conducted by the US National Center for Health Statistics, to analyze the effect of exercise intensity on mortality risk.
The study asked 7,518 American adults to wear a wristwatch-type activity tracking device to measure their activity over a seven-day period, and collected mortality data for at least four years after the measurement to analyze the relationship between the amount and intensity of exercise and mortality.
The analysis found that people who participated in high-intensity physical activity had a lower risk of all-cause mortality, especially for death from cardiovascular diseases such as stroke and arterial disease.
The graph below shows the subjects' risk of death on the vertical axis and the measured exercise intensity on the horizontal axis, and it can be seen that the higher the exercise intensity, the lower the risk of death.
'The higher the intensity of exercise, the stronger the stimulation of the heart and vascular system. This improves vascular and cardiopulmonary function, i.e. cardiovascular and respiratory performance,' says Fabian Schwendinger, a sports scientist at the University of Basel.
You might be wary of the term 'high-intensity exercise,' but Schwendinger says, 'It's not just people who do extremely intense training and end up completely out of breath who live longer. Even just walking faster than usual, taking the stairs instead of the elevator, or jogging at a slightly faster pace can have an effect.'
