Posture can affect your mood and your productivity.
When you're happy or confident, your posture tends to be more upright.
But when you're sad or depressed, your posture is more likely to sag or slouch.
It works the other way around.
If you sit upright, you'll feel more alert and energetic.
But when you slouch, you'll feel less energetic.
You can try it yourself to see the difference.
Change your posture and see how it affects your mood and energy.
Find a posture that gives you the most energy and productivity, which is probably an upright posture.
If you've done some reading about Zen, one of the things that it teaches is that body and mind are the same.
Zen master Deshimaru states, "...
mind and body are one thing, like the two sides of a sheet of paper.
" In other words, when you change your mood, it'll affect your posture.
But when you change your posture, it'll affect your mood too.
So having a good sitting posture is important to be in an energetic, productive mood.
You can invest in an ergonomic chair to help you to maintain a good sitting posture.
Not only can it help boost your productivity, but it'll help prevent back problems.
It'll also help you to maintain a good neck position.
When your neck is in a poor position, it can lead to having a stiff neck, which causes pain whenever you turn your head or look up and down.
A good posture can prevent a stiff neck.
