Scientists at the Guangzhou Medical University in China found that exercise reduces the risk of early death due to lack of sleep.
European magazine notes of Preventive Cardiology, in which researchers examined data including 92,000 people aged 40-73 who were asked to wear an accelerometer bracelet. During the seven years of follow-up, 3,080 of them died, including 1,074 from cardiovascular disease and 1,871 from cancer.
The researchers divided study participants’ sleep duration into three categories: short sleep (less than 6 hours), normal sleep (6-8 hours), and long sleep (more than eight hours). They also categorized physical activity levels into low, medium, and high, based on moderate-to-intense exercise intensity.
After adjusting for age, gender, race, education level, body mass index, diet, smoking, alcohol use, and work schedule, exercise neutralized the negative effects of too little or too much sleep.
And that in people with low physical activity and short and long sleep, the risk of death from all causes was 16 and 37 percent, respectively. For people who were moderately physically active, if they didn’t get enough sleep, their risk of premature death increased by 41 percent. The researchers did not find any association between the risk of early death and physical activity in those who engage in intense physical exercise.
And the risk of heart disease and death from them in people suffering from sleep deprivation has risen to 69 percent. However, this percentage decreased if they practiced intense or moderate physical activity. And that the chance of dying from cancer increased to 21 percent in people who slept long hours and did little physical activity. But this condition disappears in the case of moderate or intense physical exertion.
