Ergonomics helps us to design a working environment to make it more comfortable and safe for each person. Working environments don't just include activities based on earning money.

We use anthropometric design data to work out the average human body measurements. Then using this data to determine the dimensions of a chair, desk, kitchen table and the space around a workstation. But each humans individual body means adjustments are required. 

Avoid body fatigue caused by unsuitable or uncomfortable furniture.

You should avoid too many repetitive movements and don't overstretch your arms. 

For example, moving of a computer mouse or typing on a keyboard.

Any items you use regularly on your desk should be within comfortable reach. Avoid over reaching.

Your chair needs to be set at the correct height. Use a foot rest if your feet aren't touching the floor. Your feet need to be flat to the floor.

Use a cushion if your chair is to low. Make sure to support your lower back if your seat is to deep.

Place your laptop screen at eye level and at arms length. Lift up your screen if you are finding you are bending your neck down.

Take regular breaks. 

Stand up and move during tv breaks or coffee breaks.

Walk around whilst on the phone.

Swap sitting for more active breaks. Stretching or walking up and down a set of stairs.

Set up an alternative standing position for working. Make sure your laptop is setup not to high or to low.
