Everyone knows that exercising is beneficial for both body and mind, and that sitting for long periods is harmful to health. However, nowadays, urban dwellers sit for at least 7-8 hours a day, either slouched or leaning forward. How dangerous is this really?
Prolonged sitting can have a negative impact on lumbar spine health, as the load on the lumbar spine varies depending on body position. When sitting for extended periods, the middle part of the lower back is easily compressed, causing the spine to gradually lose its original elasticity, which can lead to PAIN!
Let's take a look at the significant differences in the pressure borne by the lumbar spine in various positions:
Good standing: Lumbar pressure 100% (reference point)
Lying flat: Lumbar pressure 25%
Good sitting posture: Lumbar pressure 140%
Leaning forward while sitting (Slouching): Lumbar pressure 185%
As we can see, slouching like a 'couch potato' places the greatest load on the lumbar spine, with increased pressure on the intervertebral discs becoming more pronounced. When the weight of the head, neck, and torso is concentrated on just a few support points of the lumbar spine, doing this every day—how can one avoid back pain?
In fact, as the muscles supporting the spine begin to fatigue, we all eventually end up slouching after prolonged sitting.
Do you really want to relax?
From now on, don't sit for too long. Get up every 60 minutes to take a break, walk around, and stretch!
