A sedentary lifestyle is rightly considered one of the serious problems of mankind, as it leads to numerous diseases. But this is also a paradox - in the course of evolution, all living things have learned to sit in order to rest, save energy, and maintain physiological health longer. Where we turned the wrong way, and why sitting does more harm than good to modern man, anthropologist David Reichlen of the University of Southern California tried to figure out.
Reichlen studied the life and peculiarities of life of the Hadza people from Tanzania, a tribe of hunter-gatherers who are alien to the benefits of civilization. They use the same methods and primitive technologies as their ancestors centuries ago, eating from the wild with almost no culinary processing. And they also have an incredibly low risk of cardiovascular disease - compared to overweight townspeople, the Hadza look extremely advantageous.
Scientists put sensors on the natives to collect statistics on their physical activity, and found that hadza just sit and rest for almost 10 hours a day. This is almost identical to the indicators for developed countries, but strange for the hunter-gatherer people, who are literally “fed by their feet”. True, the Hadza not so much hunt as gather vegetables and roots - they are not very high in calories, and therefore you need a lot of them. And at the same time they sit a lot, but no one suffers from obesity and does not have heart problems.
In the course of further research, scientists realized that the reason was how the Hadza sit - squatting or kneeling. Their muscles remain in a slight tension, and the body is in good shape, unlike a person who is sprawled on the couch or even works hard, but sitting in a comfortable office chair. Reichlen hasn’t made any final conclusions yet, but it’s clear that if we want to stay healthy, perhaps we just need to learn how to sit properly first.
