Several studies have suggested that sitting all day is bad for you. So a growing number of people have decided to stand all day instead. This may not be any better, and may be worse. The Healthy Programmer quotes Dr. Alan Hedge saying that standing desks increase your risks of developing carotid atherosclerosis and varicose veins, and decrease your ability to carry out fine motor tasks.
I don’t know how much to make of Dr. Hedge’s remarks. I take most fitness studies with a grain of salt (which, by the way, some studies are saying isn’t bad for you after all). But it makes sense that it’s probably best not to sit all day or stand all day but to alternate your time sitting, standing, walking, and even spending some time in a hammock.
One simple way to move around more is to not sit in front of a computer when you’re not using a computer.
