Another reason to get more active - a new study finds that being physically inactive (a couch potato) is associated with a higher risk of severe COVID-19 infection, hospitalization and ICU admission for COVID-19, and death from COVID-19. The researchers concluded that being consistently inactive should be viewed as a risk factor for severe COVID-19 outcomes, and that it is a "stronger risk factor than any of the underlying medical conditions and risk factors identified by the CDC except for age and a history of organ transplant". Yikes!
On the other hand, being physically active at least 150 minutes per week, and this includes brisk walking, is linked to lower rates of all of the above. Some activity (but under 150 minutes per week) is also better than none, but 150 minutes or more is better. The researchers state that besides vaccinations, social distancing, and mask wearing - being physically active is the single most important action individuals can take to prevent severe COVID-19 and its complications, including death.
The 150 minutes (2 1/2 hours) of physical activity per week are the recommended US Physical Activity Guidelines for adults, and include moderate and vigorous physical activity. It includes brisk walking. This can be achieved in less than 1/2 hour per day!
The researchers point out that health benefits of regular physical activity include: improved immune function, lower incidence of viral infections, as well as lower intensity and cases of death from viral infections, lowers the risk of chronic inflammation, improves cardiovascular health, increases lung capacity, muscle strength, and improves mental health. Which is why it is not surprising that persons getting a good amount of physical activity each week also generally have fewer problems with COVID-19 infections.
Some excerpts from the study at British Journal of Sports Medicine (BJSM): Physical inactivity is associated with a higher risk for severe COVID-19 outcomes: a study in 48,440 adult patients
Abstract: Objectives To compare hospitalisation rates, intensive care unit (ICU) admissions and mortality for patients with COVID-19 who were consistently inactive, doing some activity or consistently meeting physical activity guidelines. ...continue reading "Reduce Your Risk of Severe COVID-19 Infection By Being Physically Active"
