Fatigue caused by standing for long periods of time and the effects of compression stockings

Standing and the physiological effects on the lower extremities

In today's work environment, many occupations require long periods of standing, and in industries such as food processing, healthcare, and customer service, workers are typically required to stand for 70-90% of their day. In these situations, it has been pointed out that lower limb blood flow stagnation, muscle fatigue, and venous pooling are likely to occur, leading to chronic fatigue and pain (Kraemer et al., 2000). This problem is not just an individual discomfort, but is also directly linked to reduced labor productivity and increased risk of workplace accidents , making it an important issue for corporate occupational health and safety managers.

The scientific benefits of compression stockings

In this study, 12 healthy women were asked to examine the effects of stockings with different compression levels on physiological changes caused by standing work . They performed an 8-hour standing work protocol and measured changes in vascular cross-sectional area, blood pressure, heart rate, and muscle fatigue indicators (creatine kinase concentration).

Key findings

1. Reducing swelling in the legs
   • Ankle and calf edema was significantly reduced (p < 0.05).
   • Venous blood pooling (stagnation of blood in the veins) is suppressed, reducing the occurrence of edema.
2. Improved hemodynamics
   • In the group that wore compression stockings, the expansion of venous diameter was suppressed and blood flow was maintained smoothly.
   • A tendency for the drop in blood pressure after standing (delayed orthostatic hypotension) to be suppressed was confirmed.
3. Reduce muscle fatigue and damage
   • The increase in blood creatine kinase (CK) concentration after standing work was significantly suppressed, and damage to muscle tissue was reduced.
   • It has been suggested that compression stockings may reduce static load on muscles and reduce discomfort during work.
4. Improved posture stability when standing
   • Wearing compression stockings reduces body sway (shift in center of gravity) when standing, improving posture stability.
   • By stabilizing posture, fine adjustment activity of muscles is reduced, which is expected to reduce fatigue caused by standing work for long periods of time.

Recommendations for company occupational safety and health personnel

Improving the working environment in the workplace not only helps maintain employee health, but also has a significant impact on work efficiency and corporate risk management . The following measures are effective:

• Introduction of compression stockings
  • The "graduated compression design" provides strong pressure at the ankle area and gradually decreases towards the calf.
  • Research has shown that light to moderate compression provides the most comfort and effectiveness.
  • We provide employees with appropriate instructions on how to wear masks and encourage their effective use.
• Improved working environment
  • Reduce strain on employees by using cushioned mats, foot rests, and choosing appropriate shoes for standing work .
  • The fatigue reduction effect is maximized by ensuring rest periods and encouraging stretching exercises.
  • Establish guidelines for ergonomically optimal working postures and strengthen workplace safety measures.
• Prevention of Work Accidents
  • By reducing the health risks associated with standing work, it is possible to reduce workers' compensation claims and medical expenses .
  • Helps prevent chronic leg pain and fatigue through the use of compression stockings.

summary

It has become clear that wearing compression stockings reduces the strain on the lower limbs caused by long hours of standing work and suppresses muscle fatigue and venous pooling . Companies are required to actively promote the introduction of compression stockings and the improvement of the work environment, not only to contribute to the maintenance of employees' health, but also from the perspective of preventing work-related accidents and improving productivity. It is important to continue to introduce health management measures based on scientific evidence and aim to create a sustainable work environment.
