Eli5 Why does bad posture feel so…. good.
In: Biology
Basically, you are not using your muscles as much. With good posture, your muscles are active keeping your spine aligned. This means that you don’t put strain on the ligaments in your back, but obviously it requires constant adjustment by your muscles.
When you relax your muscles you’ll get more strain on your spine. You will feel more relaxed the first minute or so, but you’ll eventually become more tired and of course develop back problems over time.
EDIT: I probably gave a wrong impression. Bad posture puts strain on both the ligaments *and* the muscles in your back. I originally said it put strain on the spine. What I meant to convey is that good posture requires constant adjustment from a lot of muscles in your back. (This should happen subconsciously)
It’s not really that those muscles get tired because of over use, it’s just that it’s easier to not use them because we are inherently lazy. However good posture, like all habits, become easier over time. Back and core exercise also helps.
I should also add that the goal of these muscles is about getting your weight above your spine. The spine was made to be compressed, not stretched.
