You don’t. If you get that cramping feeling or feel bent over to one side after sitting in your chair or lifting something, you don’t throw your back out. It’s not like you sit there or do something and a vertibrae just slips out. Disks can slip out but this is rare too.
Most of the time, what’s really happening is that you’re tearing your muscles. When you exert unusual strain or sudden strain after hours of sitting still, your stiff muscles tear. When you get a tear, blood fills the torn area to repair the damage. This is a good thing. The bad part is that the blood also causes swelling. And if the swollen area happens to be near your sciatic nerves, well, it’s going to feel like your days of walking erect are over.
People who drink coffee or alcohol have this experience much more often. Both of these beverages “dry out” your muscle tissues making them “brittle,” Although in different ways. Alcohol has an extra feature where it resembles food since the alcohol becomes sugar. But since it’s a liquid, it strips your body of the vitamins and minerals it needs when urinating without giving much back. So your muscle tissue gets washed clean of the Vitamin b family.
It strips away vitamins and minerals without giving any back
So to avoid getting that kink in your back, if you drink, drink with nutritious foods heavy in Vitamin b. And stretch, get your muscles limber and resilient so minor motion doesn’t land you in bed for a week.
