Why do we move our hands while walking?

Why do we move our hands while walking? 😊😊😊😊😊😊

Curiously, human swing their arms as they
walk. That is, your right arm swings forward when your
left leg steps forward and vice versa. The first reason is
that we swing our hands naturally because it takes less
exertion than when holding the arms
down. Also, swinging arms in an opposing direction
reduces the angular momentum of the body, balancing
the rotational motion produced during walking. To
explain, during a step, your legs try to make your body
spin about a vertical axis but swinging your arms
cancels this out.
