  • *Dental drill whirring

  • Nobody likes to feel uncomfortable.

  • Especially at work.

  • When your body's out of whack, it's hard to think straight.

  • Spending too much time like that can start to have a bad affect on your health.

  • *Crash

  • Ergonomics is all about arranging our environments so we can be comfortable and safe.

  • The right equipment helps.

  • But you don't have to spend a fortune.

  • Small changes can make a big impact.

  • We'll show you how.

  • When your body’s in proper alignment, you feel better.

  • Which means you can work better.

  • It’s called a neutral body posture.

  • Your feet are flat on the floor, or on a footrest.

  • Your knees and thighs are level, or slightly lower than your hips.

  • The small curve in your lower back is supported.

  • Your shoulders and elbows are relaxed, and resting at your sides.

  • Hands, wrists, and forearms are straight, and parallel with the floor.

  • Your head is level and facing forward.

  • When it comes to chairs, one size definitely does not fit all.

  • Adjustability is the key to comfort.

  • Raise or lower the chair height so your feet are flat on the floor.

  • If your chair doesn’t go low enough, use a footrest.

  • Your feet should be slightly forward from the knees.

  • Sit with your hips as far back in the chair as possible.

  • There should be one to two inches between the backs of your knees and the front edge of the seat.

  • If the seat’s too deep, and you don’t have another chair, use a lumbar wedge or pillow.

  • There also should be one to two inches between the outside of your thigh and the side of the seat.

  • It helps to ask a co-worker to adjust the seat back while you sit in the chair.

  • That way youll know immediately when the fit feels right.

  • Some chairs offer adjustable lumbar support,

  • although a lumbar pillow is an option.

  • Make sure the lumbar support on the chair matches the natural S-curve of your lower back.

  • If you use the arm rests, your shoulders should be relaxed, not hunched up.

  • If the arm rests get in your way, lower or remove them.

  • *piano playing

  • Using a computer keyboard is kind of like playing the piano.

  • The proper body posture helps prevent injuries--and improves your technique.

  • Your hands, wrists, and forearms should be level with your elbows

  • Like this….

  • Not this….

  • Or this.

  • If you have a keyboard tray,

  • make sure it’s at the right height so that your wrists are in a straight line with your arms.

  • Your elbows should rest comfortably at your sides, at about a 90-degree angle.

  • The keyboard tray should be level or tilted slightly down.

  • This helps your wrists stay straight and in line with your forearms.

  • A wireless keyboard offers the most flexibility.

  • If the keyboard has legs, don’t use them.

  • If you don’t have a keyboard tray,

  • adjust your chair or desk height to get your arms and wrists in a neutral position.

  • Choose a wireless mouse that fits your hand comfortably and keeps your fingers relaxed

  • and slightly curved.

  • Place it close and level with the keyboard.

  • Remember, the palm rest is for quick breaks, not for support while youre keyboarding.

  • *TV static

  • People used to think that sitting too close to the TV would make you blind.

  • That’s not true.

  • But sitting too close--or far away--from your computer screen can cause eye strain,

  • not to mention give you a pain in the neck.

  • Make sure the monitor is directly in front of you and lined up with the keyboard.

  • Place it at a comfortable distance for viewing.

  • For many people, that’s about an arm’s length away.

  • The top third of the monitor should be at eye level to avoid straining your neck.

  • If you wear bifocals, trifocals, or progressive lenses,

  • you may need to lower the monitor.

  • A document holder helps when youre scanning between your desk and the screen.

  • Dual monitors should be the same size and height.

  • Think about how much time you use each monitor.

  • If it’s about the same, position them next to each other angled in slightly.

  • If you use one monitor more than the other,

  • put the primary monitor directly in front of you and the second monitor to the right or left at a slight angle.

  • Remember, both monitors should be at a comfortable distance and height for viewing.

  • *phone rings

  • Think about how much time you spend on the phone.

  • In a busy office, it's hard to avoid.

  • But you can avoid the headaches that come with poor ergonomics.

  • Place the phone close to you.

  • That way you don’t have to reach too far to dial or answer.

  • By the way, that works for other tasks too.

  • Think of your desk in terms of green, yellow, and red zones.

  • Things you use a lot, like the phone, go in the green zone.

  • Things you use less often, like files, go in the yellow zone.

  • And things you rarely use, like reference books, can go in the red zone.

  • Also, don’t cradle the phone between your head and shoulder.

  • Use a headset or speaker.

  • *clock ticking

  • Being stuck in your seat for hours is no fun.

  • It’s also not good for you.

  • At work, it’s a good idea to stand up and move for a few minutes every half hour.

  • Take walking breaks and meetings.

  • Visit a co-worker instead of instant messaging.

  • If your job involves lots of sitting-

  • -or, youre uncomfortable sitting for 30 minutes or less,

  • a sit-stand workstation might help.

  • Options include: • Fully adjustable freestanding desks

  • Height adjustable mounted desktops

  • Or a combination

  • A well-designed sit-stand workstation should accommodate many different users

  • and be easy to adjust.

  • If possible, try a few models before you commit.

  • And remember to change your position often.

  • Standing in one spot for too long can be just as uncomfortable-

  • -and unhealthy--as too much sitting.

  • Laptops, smart phones, and other mobile devices make it easy to work

  • pretty much any time and anywhere we want.

  • Just be sure you bring along your good ergonomic technique.

  • If you use a laptop regularly for work,

  • set up a workstation with an adjustable chair,

  • stand-alone keyboard, and wireless mouse.

  • Raise the screen to eye level.

  • Position it to avoid glare.

  • And make sure the keyboard is at the right height

  • so your shoulders are relaxed and your hand is at elbow level or below.

  • Studies show we tap touch screens eight times harder than regular keys.

  • If you have to type more than a paragraph on a touch screen device,

  • use an external keyboard.

  • Bottom line: While mobile devices make our lives easier in so many ways,

  • they aren’t designed to replace a proper ergonomic workstation.

  • What’s more, staring at a lighted screen late at night can disrupt your sleep pattern.

  • So be sure to shut it off at least an hour before bedtime.

  • If you can’t afford the latest ergonomic office equipment,

  • there are lots of ways to work smarter using what you have.

  • If your chair’s a bad fit, a lumbar cushion can help.

  • You can use desk risers or 2x4s to raise a stationary desk to a comfortable position.

  • If your desk is too high, raise your chair.

  • Use a footrest if your feet don’t sit flat on the floor.

  • Don’t have a footrest? A concrete block, sturdy box, or piece of wood will do.

  • Use reams of paper or a phone book to raise your monitor to the right height.

  • Remember to check out used office furniture suppliers and rent-to-own options.

  • And be sure to repair or replace equipment that becomes defective or outdated.

  • What about alternative office products that advertise themselves as ergonomic?

  • Are they really a sound investment?

  • If youre exploring alternative workstations, here are some things to keep in mind:

  • Treadmill and bicycle desks encourage movement and activity

  • but aren’t designed to be used for long periods of time.

  • Theyre also better for light tasks such as phone calls, email, or browsing the web

  • than intensive writing or reading.

  • And remember, not everyone is coordinated enough to walk or ride a bike while working.

  • The same is true for alternative seating.

  • Ask yourself these questions:

  • Does this chair provide adequate support?

  • Can I adjust the height?

  • Will this be comfortable for long periods?

  • What happens if the ball pops?

  • *pop (man screams)

  • Before you invest in alternative ergo,

  • think about the kind of work you do and how the product will be used.

  • Consider setting up a test station where employees can try it out and offer feedback.

  • Whatever equipment you choose--whether it’s new or used, innovative or improvised-

  • -it should be safe, comfortable, and provide the proper adjustability and ergonomic support.

  • Weve covered the basics for creating a comfortable and safe work environment.

  • But there’s lots more you can do:

  • The right lighting can make a big difference.

  • Use filtered lighting if glare is a problem.

  • Task lighting can help prevent eye strain.

  • Avoid working in the same position for long periods of time.

  • Alternate tasks so your muscles don’t get stiff and tired.

  • Take short, frequent breaks to rest and reenergize-

  • -a 30 to 60-second break every 20 to 30 minutes is ideal for computer users.

  • Try some simple warm-up exercises.

  • And be sure to use the same good ergonomic techniques when youre working at home

  • or outside the office.

  • Being comfortable and safe at work is a shared responsibility.

  • Employers are responsible for providing a safe and healthy workplace.

  • But employees should help figure out what works best for them.
