Which action increases the risk of low back injury and pain?

Smoking tobacco increases the risk of low back injury and pain due to several interconnected factors. Nicotine affects the blood circulation, which can impair the delivery of essential nutrients and oxygen to the tissues in the lower back. Poor blood flow can hinder the body's natural healing processes and increase the likelihood of injury. Moreover, smokers may experience an increase in inflammation and discomfort, making them more susceptible to pain.

In addition, smoking is associated with decreased bone density, which can contribute to back problems. The combination of reduced blood flow, impaired healing, and a negative impact on bone health creates a higher risk for individuals who smoke, which makes it an effective answer to the question regarding actions that increase the risk of low back injury and pain.

On the other hand, regular exercise generally supports back health by strengthening muscles, improving flexibility, and promoting endurance. Ergonomic furniture is designed to support proper posture, which can reduce strain on the spine, and Vitamin D supplements aid in maintaining bone health, thereby decreasing the risk of injuries.
