Prolonged sitting:
Prolonged sitting is the #1 worst thing for your lower back. Prolonged sitting will put a lot of pressure on your back, regardless of if you’re sitting in a supported or non-supported chair. The pressure can gradually wear down your spine, causing pain. If you sit for long periods of time and you have weak muscles, everyday activities such as; getting groceries out of the car can cause injury.

Stress:
Stress is the worst thing for your muscles. Stress weakens the muscles and causes nervous system responses that can dehydrate the discs in your spine. Weak muscles and dehydrated discs in your spine can make you vulnerable to injury. Even small activities such as tying your shoes or bending over can cause injury.
