To protect your back from injury:

Question

Quizplus · Accepted Answer

When sitting for long periods, it is important to get up and stretch or walk around to prevent stiffness and strain on the back. Standing with weight evenly distributed is also helpful, but not as crucial as taking breaks from sitting. Sleeping on a soft, curved mattress can actually be harmful to the back as it does not provide enough support for the spine. Lastly, bending at the waist instead of knees when lifting places a greater strain on the lower back and should be avoided.
