Productivity Meets Ergonomic Design

Employees spend an average of 96.1 hours per week in front of screens—equivalent to four full days. Over a year, this amounts to 208 days of screen time or 57% of the entire year.1

That extended amount of time can lead to more ergonomic concerns. According to the US Bureau of Labor Statistics, musculoskeletal disorders (MSDs) are responsible for over 1 million workplace injuries annually in the U.S., costing an estimated $20 billion in workers’ compensation claims.2 It is estimated that as much as 33% of workers compensation costs in the US are due to ergonomic-related injuries.

Research from around the globe also finds that over 60% of all people who work with computers experience pain from repetitive strain injuries in the wrist, hand, neck, and shoulders.3

Ergonomics isn’t just critical for physical wellness. It can also impact productivity. 60% of workers who missed work due to musculoskeletal injuries experienced reduced productivity after they returned to work.4

Decreased productivity from ergonomic injuries doesn’t just affect individual workers—it ripples throughout entire teams and departments. As tasks pile up and output decreases, the overall performance of the department can suffer. For departments that depend on speed and efficiency, especially where downtime is costly, ergonomic injuries pose a significant threat to maintaining productivity and meeting mission objectives.

No matter the setup or where work takes place, simple actions can help improve employee well-being and enhance productivity.

Ergonomic Strategies

Considerations to improve wellbeing and productivity

Držení těla

When laptops are used on a desk, the head angles down by about 10 degrees. When placed in a person’s lap, that angle increases by 5 degrees. That tilt makes the head feel double its weight putting extra strain on the neck and shoulders.5

Řešení

Obrazovky notebooků a tabletů umístěte do úrovně očí, zejména na delší dobu viewobdobí.

Banish Glare

Glare can increase eye strain. Eyes adapt to the brightest level of light, so it becomes harder to see details in duller and darker areas.

Řešení

Place screens perpendicular to windows. Close curtains or shades while working.

Hnutí

The human body is not designed to sit or stand all day, it is designed to move. Quick movement breaks show marked improvement in cognitive function, reading comprehension, and productivity.6

Řešení

Switch between sitting and standing in 30-60 minute intervals. Walking around while standing is even better.

Ergonomic Solutions for Mobile and Hybrid Work

Mobilní nastavení umožňují větší flexibilitu, ale také zvyšují šance na práci v neoptimálních podmínkách. To zvyšuje riziko nepohodlí nebo dokonce bolesti. Krk a ramena jsou obzvláště zranitelné.

Read on for realistic tips that employees can practice to optimize workstations for ergonomic impact.

The background is a blurred indoor setting with a window and some plants.

Optimizing Setups With Laptops and Tablets

With laptops and tablets, the screen and input are tethered together, forcing an ergonomic trade-off: Adjusting one to improve ergonomics may worsen the ergonomics of the other.

Adjusting to the screen

Pokud je obrazovka v ergonomické vzdálenosti a výšce, může být obtížné dosáhnout a držení ruky a zápěstí může být nepříjemné bez použití externích periferií. To může zvýšit riziko nepohodlí a napětí.

Adjusting to the input

If the device is placed so that input devices are used comfortably, then the screen will likely be too close to the employee, and too low, increasing the risk of eye strain and the risk of neck and shoulder strain.

Řešení

Laptop, table stands, and external mice and keyboards such as the Logitech Ergo M575 a Ergo K860, provide ergonomic benefits. A lifted screen encourages a more natural neck posture and helps reduce neck and shoulder strain, while an ergonomic mouse and split ergonomic keyboard can help minimize movement, maximize comfort, and offer better posture, less strain, and more support. Because these screens tend to be smaller, adjusting the font size can also help reduce eye strain.

Positioning tablets

  • Nedávejte tablety na klín nebo je nedržte v rukou.
  • Place tablets on a surface (table or desk) to reduce wrist strain and neck strain from looking down at the screen.
  • Umístěte tablety na délku paže, abyste snížili únavu očí, a v případě potřeby zvyšte velikost písma, abyste lépe viděli.
  • Use a flexible kickstand, like that found in the Logitech Rugged Folio, with 40° of tilt for the right angle for the task at hand.

Adjusting to the work

  • When reading, watching, and typing with an integrated physical keyboard, use the steeper angle on a stand, and avoid placing the tablet flat on a table.
  • V případě potřeby podložte notebook nebo tablet knihami, abyste snížili namáhání očí a krku.
  • When drawing, writing, or typing on a virtual keyboard, use the lower angle of the stand, or lay the device flat on a table for a better hand and wrist position.

Headsets for Effective Communication

Headsets and external microphones with good sound quality and noise cancellation can help provide more effective communication. Using headsets, especially those with built in microphones, offer a number of ergonomic and well-being benefits.

Výhody

  • Employees are less likely to lean towards the computer or tablet to hear or be heard, which helps reduce strain on eyes, neck, and back.
  • Wireless headphones allow employees to move around while listening, which helps to avoid prolonged stationary positions.

Úvahy

  • The World Health Organization recommends that sound levels should be adjusted to less than 75 decibels (or no more than 60% of the maximum volume).5
  • Regular breaks are recommended, especially when employees wear headsets for extended periods.

Ergonomic Solutions for Desktops

Technology for desktops is important too. The right tech can save energy, help employees focus, and promote overall well-being. Using external peripherals—like an external screen, webcam, mouse, and keyboard—can create an optimal desk setup and offer microadjustments that can make a big difference.

The Ideal Setup

Externí Webvačka

Externí webcam like the TAA-compliant Logitech Brio 505 placed on top of an external screen rather than on a laptop helps employees look straight ahead. This improves neck posture and reduces neck and shoulder strain.

Externí obrazovka

Positioning the laptop at the right height and distance reduces the need to bend the neck. To improve posture and minimize neck, shoulder, and eye strain, place the laptop on a stand.

External Mouse and Keyboard

External peripherals like the Logitech Lift Mouse a Vlnové klávesy allow employees to select the device that is the right size for them and with the right functionalities for their unique tasks. This encourages long-lasting comfort and productivity.

Headset and External Microphone

Using a headset like the Logitech H390 or Zóna 305 (with a built-in or external mic) ensures that employees can hear and are heard better, and reduces the need to lean forward which can put strain on your back.

Posture and Positioning in the Office or Working From Home

No matter what setup an employee chooses, these guidelines should be the aim.

  • Place feet flat on the floor with knees, ankles, and hips at about 90° angles.
  • Keep elbows at about 90° when typing or using a mouse.
  • Zajistěte oporu dolní části zad pomocí opěradla nebo polštářů.
  • Podepřete stehna úpravou sedací části nebo si sedněte více dozadu na židli.
  • Avoid crossing legs, sit up straight, and change positions from time to time.

By addressing common challenges in office, field, and hybrid setups, proper ergonomic practices across government workspaces can help boost productivity also while enhancing employee well-being, supporting accessibility, and lowering costs related to absenteeism and healthcare.

Troubleshooting Common Ergonomic Problems

  • Neck/shoulder strain from laptop/tablet use: lift the screen to eye level and avoid placing tablets in laps. If using a laptop on a desk, reduce downward head tilt by raising the device (e.g., use a stand).
  • Eye strain or difficulty seeing due to glare: rotate screens so they’re perpendicular to windows, and close curtains/shades while working.
  • Discomfort from long stationary work: schedule short movement breaks and alternate sitting/standing every 30–60 minutes; walking while standing is even better.
  • Drowsiness, headaches, or poor concentration: improve ventilation by opening a window for a few minutes several times per day.
  • Reduced hearing clarity while working: use headsets or external microphones with good sound quality/noise cancellation, and take regular breaks for extended headset use.

FAQ

How should I position a laptop for better posture?
Place the laptop/tablet screen at eye level, especially for longer viewing periods. The guide notes that head angles down about 10° when a laptop is on a desk, and increases by an additional ~5° when placed in a lap—so raising the screen helps reduce neck/shoulder strain.
What can I do to reduce glare on my screen?
Place screens perpendicular to windows, and close curtains or shades while working to reduce glare and eye strain.
How often should I switch between sitting and standing?
Switch between sitting and standing in 30–60 minute intervals. Walking around while standing is even better.
If I feel drowsy or have trouble concentrating, what ergonomic change is recommended?
Open a window for a few minutes several times per day to bring in fresh air. The guide links elevated CO2 levels to drowsiness, headaches, and loss of attention.
