Australian scientists have found that the time of day you exercise may reduce your risk of death.

Cardiovascular diseases are the leading cause of death worldwide and kill more than 650,000 people annually in the United States. However, not everyone is at the same risk for cardiovascular disease. People with type 2 diabetes and people with obesity They have a much higher risk of developing fatal cardiovascular disease.

For these people, not all hope is lost; it was shown that Aerobic exercise reduces the risk of mortality in this group of adults.. However, there is a way to maximize the benefits of moderate to vigorous exercise: time.

A recent study from the University of Sydney in Australia found that Nighttime exercise is best for reducing mortality rates in this predisposed group.

Reduced risk of cardiovascular disease associated with nighttime exercise

The researchers took a sample of 29,836 adults who had been obese for nearly 8 years. They tracked when they achieved aerobic movement lasting more than 3 minutes.. Participants were asked to wear a wearable device that monitored their heart rate. Any activity that increased your heart rate by 3 minutes was counted, such as climbing stairs, brisk walking, running, or even vigorous house cleaning.

They were followed with the device for only one week and then tracked through a health database for 7.9 years. Of the 1,425 deaths in the study, in the nighttime exercise group, the risk ratio was only 0.39.. Morning athletes performed much worse with a coefficient of 0.67. The study also found similar results for cardiovascular events.

Important discovery for healthcare

This is the first result of its kind obtained on such a large scale. Although the researchers expect more studies are needed to confirm the results, it is a simple step that doctors can recommend to their patients. Switching from morning to evening workouts is a simple change that can save lives..

Healthcare professionals may consider recommend more exercise at night How preventive and control practice For those who are predisposed to cardiovascular problems. Reducing your risk by almost a third makes a big difference for such a small lifestyle change.

The researchers did not link activity intensity to time, but higher training intensity is likely to increase these benefits. Research like this is incredibly important because cardiovascular diseases are still the reason 1 in 5 deaths in the US and the reason million deaths per year worldwide.
