Understanding Ergonomics
HereÂareÂsomeÂtipsÂforÂsettingÂupÂaÂhealthyÂworkÂ
environment.

Keyboard

WhenÂyouÂuseÂtheÂkeyboard,ÂyourÂshouldersÂshouldÂbeÂ
relaxed.ÂYourÂupperÂarmÂandÂforearmÂshouldÂformÂanÂ
approximateÂrightÂangle,ÂwithÂyourÂwristÂandÂhandÂinÂroughlyÂ
aÂstraightÂline.
ChangeÂhandÂpositionsÂoftenÂtoÂavoidÂfatigue.ÂSomeÂ
computerÂusersÂmightÂdevelopÂdiscomfortÂinÂtheirÂhands,Â
wrists,ÂorÂarmsÂafterÂintensiveÂworkÂwithoutÂbreaks.ÂIfÂyouÂ
beginÂtoÂdevelopÂchronicÂpainÂorÂdiscomfortÂinÂyourÂhands,Â
wrists,ÂorÂarms,ÂconsultÂaÂqualiedÂhealthÂspecialist.

Mouse

PositionÂtheÂmouseÂatÂtheÂsameÂheightÂasÂtheÂkeyboardÂandÂ
withinÂaÂcomfortableÂreach.

Chair

AnÂadjustableÂchairÂthatÂprovidesÂrm,ÂcomfortableÂsupportÂ
isÂbest.ÂAdjustÂtheÂheightÂofÂtheÂchairÂsoÂyourÂthighsÂareÂ
horizontalÂandÂyourÂfeetÂareÂatÂonÂtheÂoor.ÂTheÂbackÂofÂtheÂ
chairÂshouldÂsupportÂyourÂlowerÂbackÂ(lumbarÂregion).ÂFollowÂ
theÂmanufacturer’sÂinstructionsÂforÂadjustingÂtheÂbackrestÂtoÂ
tÂyourÂbodyÂproperly.
YouÂmightÂhaveÂtoÂraiseÂyourÂchairÂsoÂthatÂyourÂforearmsÂandÂ
handsÂareÂatÂtheÂproperÂangleÂtoÂtheÂkeyboard.ÂIfÂthisÂmakesÂ
itÂimpossibleÂtoÂrestÂyourÂfeetÂatÂonÂtheÂoor,ÂyouÂcanÂuseÂ
aÂfootrestÂwithÂadjustableÂheightÂandÂtiltÂtoÂmakeÂupÂforÂanyÂ
gapÂbetweenÂtheÂoorÂandÂyourÂfeet.ÂOrÂyouÂcanÂlowerÂtheÂ
desktopÂtoÂeliminateÂtheÂneedÂforÂaÂfootrest.ÂAnotherÂoptionÂ
isÂtoÂuseÂaÂdeskÂwithÂaÂkeyboardÂtrayÂthat’sÂlowerÂthanÂtheÂ
regularÂworkÂsurface.

Display

ArrangeÂtheÂdisplayÂsoÂthatÂtheÂtopÂofÂtheÂscreenÂisÂslightlyÂ
belowÂeyeÂlevelÂwhenÂyou’reÂsittingÂatÂtheÂkeyboard.ÂTheÂbestÂ
distanceÂfromÂyourÂeyesÂtoÂtheÂscreenÂisÂupÂtoÂyou,ÂalthoughÂ
mostÂpeopleÂseemÂtoÂpreferÂ18ÂtoÂ28ÂinchesÂ(45ÂtoÂ70Âcm).
PositionÂtheÂdisplayÂtoÂminimizeÂglareÂandÂreectionsÂonÂÂ
theÂscreenÂfromÂoverheadÂlightsÂandÂnearbyÂwindows.ÂÂ
TheÂstandÂletsÂyouÂsetÂtheÂdisplayÂatÂtheÂbestÂangleÂforÂ
viewing,ÂhelpingÂtoÂreduceÂorÂeliminateÂglareÂfromÂlightingÂ
sourcesÂyouÂcan’tÂmove.
