Okay Twitter.

A lot more of us are WFH now, so it's ergonomics time.

One of the skills I picked up while working in my last career in Healthcare was becoming a California-certified ergonomic evaluator.

I want to share some tips with all of you.

First up is ideal monitor height!

You want the top of your monitor to be flat inline with your eyes when you're sitting leaned back in your chair. Woman at desk illustrating ideal computer monitor height

You know how people get high-end mice to move in games without moving their hands much?

That's a really good thing. You don't want to be cranking your wrist sideways.

Repeatedly straining/compressing your wrist will give you a Repetitive Strain Injury (RSI). Illustration of proper hand positions while using a mouse

You want your arms to be hanging at your side and at a greater-than-90-degree angle.

Ideally, your forearms should slope slightly downwards towards your keyboard and mouse. Illustration of the ideal typing position at a desk

You also don't want to rest your elbows on the chair arms while leaning forward to type.

It compresses your ulnar nerve, and you can end up with the pinky finger version of carpal tunnel someday. 😬 Man sitting improperly while leaning on armrests of chair

Lower or remove the arms on your chairs.

Also, make sure that your body (legs + back) is at a greater-than-90-degree angle (to reduce pressure on your body). Person sitting with greater-than-90-degree angle between their body and legs

Your feet should sit flat on the ground. If you can't reach the ground, get a footstool.

Watch out for pressure on the backs of your knees. It means your seat it too far forward and is cutting off circulation/putting extra stress on your body ⤵️ Person sitting with lots of pressure on the inside of their knees

Standing desks are great! However, people often overcorrect and stand for too long at once.

Frequently standing in one place for more than 60 minutes can actually give you lower back pain.

Switch often between sitting/standing up, and step way from your desk sometimes.

Speaking of stepping away, that's a core part of ergonomics.

Walking around your house for even 3-5 minutes every hour increases circulation and boosts your metabolism a bit.

Closing thoughts:

1.) If you're going to invest money in WFH, a really nice chair is a one of the best "bang for your buck" values out there

2.) Don't stress if you mess up with posture.... I still struggle with a lot of this stuff too, and I did a whole training on it
