Long Computer Sessions Could Cause Blood Clots
kac5 writes "The Australian reports that extended stints in front of the computer can cause blood clots to form such as those that occur from Deep Vein Thrombosis. Researchers have named it e-thrombosis (what is it with naming everything to do with computers e something?). So /.'s get up out of your chair, slowly so not to make your body go into shock, and walk to the other side of the room and back. Now do that every hour and you should be right according to this article!"
Now, all of this scientific stuff is great.
OK, all of us here are going to die from blood clots while our arms are aching from carpal tunnel syndrome...
What I'd really like to see is some general data on roughly how many hours (per day or per week) people are spending in front of a computer to get symptoms like these, and after how many years.
Is it because it's 'too random to judge accurately' or something like that? Or have they (meaning 'people smarter than myself') just not narrowed it down yet?
Here's what you do: you have to stop every four hours of sitting and do some stretches, and take a 10-15 minute walk OUTSIDE.
I used to be a PCB designer, which involves moving the mouse and clicking A LOT, with very little keyboard interaction. Instant tendonitis. The solution was to get those hand grip spring thingies, every 15 minutes I'd stop and do 15 grips per hand.
What happens is that mousing is an incomplete movement, the tendons and muscles stay in a low state of tension, which is unnatural and prevents circulation.
Stretching helps promote circulation.
I recommend the same for all computer jockeys. Some stretches, some walking. Hey I'd recommend a gym and some weights, but this IS slashdot...
That is why hard-working coders (like you, me and everyone who reads /. 7 times an hour) drink so much coffee. In one our, either you stand up and go get some, or you go to the bathroom.
We had already solved the problem before they "e-discovered" it.
A couple of years ago (when I was 31) I came down with Deep Vein Thrombosis in my liver.
I needed a liver biopsy (not fun) and six months on blood-thinners and twice-weekly blood tests.
At the time the doctor couldn't explain a cause, as I was way younger than people who usually get this, but now it makes perfect sense, as I'd been doing a lot of dawn-to-midnight programming in a very comfy new chair...
Water. Exercise. Got it.
In late November of 2001 I was walking near my house and felt a rather sharp pain in my right thigh about 4" away from the pelvis connection. Went to MGH (Massachusetts General Hospital) thinking that perhaps I had cracked my pelvis (about what it felt like) but the scans showed I had DVT (Deep Vein Thrombosis).
The doctors asked if I had been on an airplane recently as this is often seen in people who sit in cramped positions for long periods of time. I had not. But I was working as a low-level NOC monkey. Combine that with my computer activities post-work and you have pretty much the same thing minus the cramped aspect. But the doctors seemed to discard that theory.
Just to sew the story up, I took self-administered shots of Fragmin for about 2 weeks and then coumadin/warfarin (blood thinners) for about 8 months. The Fragmin is necessary because the warfarin will cause blood thickening when starting off so the Fragmin counters this. I should mention that Fragmin is incredibly expensive ($50/ea shot, 2x a day IIRC) so not having health insurance would have really sucked.
But the only thing I can think of that would have caused it is long hours at the computer. Of course it might have had a genetic origin but I've never heard of anyone in my family having it.
