Explanation

When you bend over, especially if you do it a lot or in the wrong way, it can cause your lower back to hurt. This is because bending forward puts pressure on your spine and muscles, which can lead to pain.

Why Bending Hurts:

Spinal Stress: Bending forward can increase the load on your spine, especially on the discs between the bones in your back.
Muscle Strain: Your back muscles have to work hard to support your body when you bend, which can cause them to get tired and sore.

Tips to Help:

Posture: Try to keep your back straight and bend at the hips and knees instead of your waist.
Breaks: Take breaks if you need to bend over for a long time.

Using good posture and taking breaks can help keep your back healthy and prevent pain. If your back pain continues, you can check your symptoms to better understand what might be causing your discomfort and whether you should seek medical attention.
