This Labor Day, Your Body Is on the Clock

Most people do not think about how their job affects their physical health until something starts to hurt. By then, the pattern has usually been building for a while. Different jobs create different problems. Walking for hours on end strains the lower body. Sitting at a desk all day puts pressure on the neck and back. Heavy lifting at a construction site can lead to serious lower back injuries.  Here is a breakdown of the most common issues workers face and what PT can do about each one.

People who work at a desk all day

The problem with sitting all day is not just discomfort. Research found that office workers who sat for four or more hours without changing positions had a significantly higher risk of musculoskeletal disorders, which are disorders in your body’s support structure. Workers who changed positions from sitting to standing or walking every hour reduced that risk by more than 30%.

For desk workers, the most common issues are:

• Neck pain from staring at a screen in the same position for hours
• Upper back tightness from rounded shoulders
• Hip tightness from sitting with knees bent all day
• Lower back pain from sustained pressure on the spine

Physical therapists assess posture, identify which muscles are weak or tight from prolonged sitting, and build a plan that addresses the root cause rather than just the pain.

Movements to do before the workday:

• Chest rotation: Sit upright, cross arms over the chest, and rotate side to side 10 times. This counteracts the forward rounding caused by sitting at a desk.
• Standing hip flexor stretch: Step one foot forward, tuck the pelvis slightly, and hold for 30 seconds per side. This addresses the tightening that happens when the hip stays bent for hours.
• Chin tucks: Gently draw the chin straight back, hold for five seconds, and repeat 10 times. This resets forward head posture before the workday begins.

People who work in construction or a factory

Musculoskeletal disorders are one of the most persistent health challenges in construction. Research shows that one in five construction workers experiences sprains, strains, and soft tissue injuries that tend to worsen and become long-term problems. Back, knee, and shoulder injuries are the most common, driven by heavy lifting, kneeling, overhead work, and repetitive motion.

The specific risks for these workers include:

• Shoulder injuries from sustained overhead work
• Knee pain from kneeling and squatting on hard surfaces
• Lower back injuries from repeated lifting and twisting
• Hand and wrist pain from vibration and repetitive tool use

Physical therapists work on correcting movement patterns that are loading joints incorrectly before they cause serious injury, as well as building targeted strength for the specific demands of trade work.

Movements to do before the workday:

• Shoulder circles and arm swings across the body: 10 repetitions in each direction. This warms up the shoulder joint before overhead work.
• Slow bodyweight squats: 10 repetitions with attention to keeping the knees tracking over the toes. This activates the muscles that protect the knee during kneeling and squatting.
• Cat-cow: On hands and knees, alternate between arching and rounding the back 10 times. This loosens up the lower back before it takes on load.

Nurses, restaurant, and service workers

Healthcare workers face some of the highest rates of work-related physical injury across all professions. Studies found that musculoskeletal pain in nurses and nursing aides was most common in the lower back, followed by the shoulders and neck. Servers and other service workers who spend full shifts on their feet, bending, carrying, and moving with limited breaks also show similar signs of strain.

The specific risks for this group include:

• Lower back pain from sustained standing and repeated bending
• Foot and ankle fatigue from hard floors and long shifts
• Shoulder and wrist pain from carrying and lifting
• Cumulative fatigue that builds during a shift and never fully resolves

Physical therapists assess how a person moves and where they are compensating, build strength programs for the lower body, and teach safer body mechanics for the bending and lifting that happens dozens of times a day.

Movements to do before the shift:

• Calf raises: 15 slow repetitions. This activates the lower leg before hours of standing on hard floors.
• Standing hip circles: 10 in each direction per side. This warms up the hip joint before repeated bending movements.

Teachers

Teaching is more physical than it looks. Studies find that 68% of teachers experience musculoskeletal disorders. Neck and lower back pain were the most common, each affecting nearly half of those studied.

Teachers move constantly between standing, sitting, and crouching to student level. They carry heavy bags, often on one side. They write on boards with their arm raised. Unlike desk workers, they rarely sit long enough to rest, but unlike construction workers, they rarely move in ways that build strength either.

The specific risks for teachers include:

• Neck and upper back pain from crouching to student level and working at low surfaces
• Shoulder and back pain from carrying heavy bags
• Lower back fatigue from the constant movement of a classroom day
• Arm and wrist pain from repetitive writing and grading

Physical therapists address the one-sided patterns that develop from carrying heavy bags, build strength for the transitions teachers make dozens of times per day, and correct the posture habits that accumulate across a school year.

Movements to do before the school day:

• Single-leg balance: Stand on one foot for 30 seconds per side. This builds stability.
• Neck side bend and rotation: Gently tilt and rotate the head through its full range, five repetitions each direction. This addresses the neck stiffness that comes from looking down at student work and up at boards throughout the day.
• Doorway chest stretch: Standing in a doorway, put each arm on the door frame at a 90 degree angle and lean forward gently. This counteracts the rounded shoulder posture that develops from carrying bags and working at low surfaces.

When to consider CPT’s Return to Work Program

Sometimes the issue goes beyond everyday wear and pain. If a workplace injury has kept someone out of work, or has made it difficult to keep up with the physical demands of the job, CPT’s Return to Work Program offers a structured path forward. The program includes an assessment to identify the underlying cause of pain, an evaluation to measure what the body is currently capable of in a work context, and a conditioning program built around the specific demands of the patient’s job. The goal is not just to feel better. It is to be ready to work safely.
