It turns out that the adverse health effects of lack of sleep can be offset by moderate exercise



Sleep deprivation is known to have adverse health effects such as

blood sugar fluctuations and an increased risk of dementia. However, a research team at the University of Sydney has shown that ensuring adequate exercise time can offset the negative effects of sleep deprivation.

Poor sleep is really bad for your health. But we found exercise can offset some of these harms

Less sleep, less than 7 hours a day, has been shown to increase the risk of obesity and heart disease. However, according to the research team, little research has been done on the interaction between sleep time and daily exercise. Therefore, the research team obtained health survey data for 380,55 people collected by the UK Biobank program and classified sleep status into three stages: healthy, intermediate, and poor. ..

In addition, based on the World Health Organization (WHO) physical activity guidelines , moderate exercise for 300 minutes or more per week, or strenuous exercise such as running, swimming, or soccer for 150 minutes or more per week. Classify those who are 'highest' and those who do moderate exercise for 150 minutes or more per week or strenuous exercise for 75 minutes or more per week. I classified it as 'People who go a little (Low)'. In addition, 'Medium' and 'No MVPA' were added to classify the intensity of physical activity into four levels.

In the graph below, the vertical axis shows the combination of physical activity intensity (PA) and sleep state (Sleep), and the horizontal axis shows the risk of death from cancer. Looking at the graph, we can see that for people who are not exercising at all (No MVPA), people with healthy sleep (Healthy) have a lower risk of death than people with sleep deprivation (Poor). However, it can be seen that people with physical activity (Low, Medium, High) have a lower risk of death than those who do not exercise regardless of their sleep status.



Next, when checking the graph showing the relationship between the intensity of physical activity and sleep state and the risk of death due to heart disease, the risk of death of 'people with active physical activity and lack of sleep (High Poor)' is 'exercise. It can be seen that the risk of death is lower than that of 'people who are deficient and sleep deprived (No MVPA / Poor)'.



'This study shows a link between proper physical activity and reduced harm from sleep deprivation, but care must be taken in interpreting the causal relationship between the two,' said the research team. 'I can't say that it will help reduce the harm caused by sleep deprivation,' he said. 'This study provides a hopeful message that moderate exercise can offset the negative health effects of poor sleep.' I am. '
