When we sit for a long time or have an excessively sedentary life, we increase the risk of suffering a venous thromboembolism (TEV), an important cause of morbidity and mortality in developed countries. This explains, for example, why pregnant women or patients who cannot move for a certain period of time are prescribed anticoagulant medications. However, surprisingly, those people who remain immobilized for longer periodswhether due to injury or illness, have less likely to experience this type of obstruction of the circulatory system. Because? A scientific team has discovered that the culprit is a protein that self-regulates after long periods of activity and is present in both bears and humans.

Those people who remain immobilized for longer periods have less risk of thrombi.

Bear hibernation is one of the great mysteries of nature. During this period of inactivity, unlike other hibernating mammals, such as marmots or bats, the body temperature is not greatly reduced, but it drops only about 5 degrees Celsius (from about 38 to about 33 degrees). Yes indeed, metabolism keeps working, although slowed down to the bare minimum. They don’t even urinate or defecate.
