Those who exercise either early or late in the morning were 11% and 16% respectively at a lower risk of coronary artery disease. Those who exercise later in the morning were 17% less likely to have a stroke than those in the control group.
Two-minute bursts of vigorous physical activity totaling 16 minutes per week were associated with an 18% reduced risk of death and a 15% reduced risk of cardiovascular disease. Burst exercise up to 53 minutes per week is linked to a 36% lower risk of death from any health cause.
Study adds to a growing body of evidence that stress in the workplace, coupled with impaired sleep, increases the risk of cardiovascular disease and coronary mortality, especially in hypersensitive workers.
