What brings lumbago (lumbar vertebrae pain) and how to deal with it.

M: hi
U: hi
M: how r u?
U: much better now
U: thanks for asking
U: and you
M: I’m ok.
U: just OK
U: not great
M: I watched a video one day, so just now, I changed the way I use the computer.;)
U: tell me about it
M: it’s about waist.
M: It said that if you weight 72 kg, when you stand straight, the spine on your waist just takes the pressure about 66kg.
U: waste or waist?
U: oh ok
U: yes…i believe that
M: but if your body tilts forward, it will take more than 300 kg.
M: so, if your posture isn’t straight on the chair, your spine on the waist will have to bear too much pressure, and then you will get problem on the spine.
U: yes…of course
U: thats why its important to have a good chair
M: And, the psychological stress also can bring the pressure to the spine.
M: there is a test in that video
U: i know that from my last job
M: just to do a simple adding caculation and judge it’s odd or not, can add up to 70kg pressure to the spine.
U: thats good to know
U: it sounds like your were having back pains
M: so, I removed my chair and put a blanket on the floor. Now I kneel on it to use the computer .
M: I have waist pain.
U: so now you worship the computer like God
M: (mm)
U: but…yes…that method is great
M: it can make sure that I don’t tilt forward
U: but then you will have knee pain in the future perhaps
M: :S
U: but whatever is comfortable for you
U: i like laying on my back sometimes when i use my laptop
M: yeah. I’m thinking when the weather gets warm, I will buy a bicycle to ride around. It will be good for health.
M: that video said that walking and running is good for spine.
