My only issue is that none of this is specific to web workers and much of this advice is obvious.

As a developer I often do 2-3 hour stints in front of the computer, I then stand on the balcony for 5-10 minutes, get some fresh air and clear my head, then get back to it. Its how I need to work to so I can get off at 5:30-6pm. Breaks are great but ultimately they mean longer working and less personal time. Less time equals more stress, less fun and less time to get out and socialise.

You have touched on exercise but do not give any information on why it is good. Personally I exercise most days, I find a sleep better and wake up easier after a work out. However, as a web worker I don’t quite understand how a person exercising frequently would perform better than someone not.

Regular meals is obvious for most people, however again you do not really talk about why this matters. What is wrong with a bag of crisps for breakfast, some chips for lunch and a microwave meal for dinner? Oh no! Salt! Calories! I mean honestly, would diet benefit my work?

If you could link regular meals + exercise with higher productivity then this article would have been worth reading. As is it just seems to be a reminder to do the obvious.
