Staying at home for a long time has a bad effect on the body, weakens the heart and lungs, and can impair brain function. Only the first week of self-isolation can be considered comfortable.
This is the article by CNN. Scientists interviewed by journalists note that it takes months to build muscle, and you can lose muscle weight in a week. "Humans, for all our stamina, lose muscle faster with age," said Keith Baar, professor of molecular exercise physiology at the University of California. If there is no workout, the heart rate does not rise. "And when the heart is not beating so hard, it weakens," Baar said.
Cancellation of sports is also bad for the lungs. Dr. Panagis Galiazatos, a pulmonologist at Johns Hopkins Medical Center, said many of his patients complained of worsening respiratory function after stopping exercise.
Another danger of self-isolation is named - not a regular meal, but almost constant, since there is a refrigerator nearby. If a person is usually used to taking the most high-calorie food from 10 to 15 hours, then under quarantine this interval is shifted to the afternoon. Insulin levels jump, stimulating fat storage and the conversion of other molecules into fat, said Giles Duffield, professor of anatomy and physiology at the University of Notre Dame, Indiana. This can lead to the development of chronic diseases such as metabolic or diabetes.
Another problem is that endless sitting and lying all day long can seriously affect your posture and strain your back, neck, shoulders, hips, and eyes. This was warned by Brandon Brown, an epidemiologist and professor at the University of California.
In addition, sleep quality can be affected. Self-isolation can even slow down the brain as exercise produces certain chemicals in the brain that break down toxins in the blood and even prevent them from reaching the brain, where they can kill its cells.
