So why is squatting so good for us? And why did so many of us stop doing it?

It comes down to a simple matter of “use it or lose it,” says Dr. Bahram Jam, a physical therapist and founder of the Advanced Physical Therapy Education Institute (APTEI) in Ontario, Canada.

“Every joint in our body has synovial fluid in it. This is the oil in our body that provides nutrition to the cartilage,” Jam says. “Two things are required to produce that fluid: movement and compression. So if a joint doesn’t go through its full range—if the hips and knees never go past 90 degrees—the body says ‘I’m not being used’ and starts to degenerate and stops the production of synovial fluid.”

A healthy musculoskeletal system doesn’t just make us feel lithe and juicy, it also has implications for our wider health. A 2014 study in the European Journal of Preventive Cardiology found that test subjects who showed difficulty getting up off the floor without support of hands, or an elbow, or leg (what’s called the “sitting-rising test”) resulted in a three-year-shorter life expectancy than subjects who got up with ease.

In the West, the reason people stopped squatting regularly has a lot to do with our toilet design. Holes in the ground, outhouses and chamber pots all required the squat position, and studies show that greater hip flexion in this pose is correlated with less strain when relieving oneself. Seated toilets are by no means a British invention—the first simple toilets date back to Mesopotamia in the fourth millennium B.C., while the ancient Minoans on the island of Crete are said to have first pioneered the flush—but they were first adopted in Britain by the Tudors, who enlisted “grooms of the stool” to help them relieve themselves in ornate, throne-like loos in the 16th century.
