A very common ergonomics advice that we read online for workplace health problems about injuries such as repetitive strain injuries (also commonly known as "RSI") is that we need to take short but frequent breaks. Most of of the time, we hear suggestions that we should take a 5-minute break every 50-55 minutes.
You see, most of the physical stresses we face comes mainly from muscle/muscular fatigue.
When muscles are fatigued (tired) then the muscles don't work optimally (ie sub-optimal performance), it's like trying to go for a jog when you're already tired.
What tired muscles need is simply they need rests from time to time to recover...and achieving the RIGHT amount of muscle recovery to right rest time may be a little tricky, but it's not that difficult.
Low fatigue is like typing an article for 30 minutes versus high fatigue is going for a more intense 1-2 hours tennis/hike/marathon - different fatigue level. The general consensus is that once your muscles become fatigued, tired and sore, recovery will take a long time.
Think of how your body feels after an intense/strenuous exercise work out session.
One solution to low muscle fatigue is micro breaks.
These are very short (hence "micro-breaks") of 5 to 10 seconds every 5 to 10 minutes of
These micro-breaks serve to:
These breaks are small enough to not get in the way of your work but done repeatedly, can bring big relief and help to your tired muscles.
