On headaches

I've been tracking my headaches over the past two weeks. The first week I reduced my caffeine intake, on the chance caffeine was making them worse. The second week I've had no caffeine at all. I spent a little time this afternoon making plots- when I had headaches, and when I've had to take Tylenol.

I also grabbed the air-pressure data for our local weather station, and plotted the 15-minute air-pressure differentials- I've been curious about this association, and melted_snowball told me it's a wives' tale that you can predict air-pressure changes by observing headaches.

What can I say?

The obvious: I get a fair number of headaches. I've taken 16 extra-strength Tylenols in the time period. There were three days I didn't take any. Four days I took two, one that I took three.

It appears caffeine helps cut down on headaches- I took 12 Tylenols in the last week, and 4 in the previous week.

I can't say anything useful about air-pressure. I had lots of headaches when the air-pressure wasn't particularly variable. But I also get headaches from other sources, such as, um, staring at the computer too long without a break.

The air-pressure data is... shaggy. It only changes in increments of .03 kPa or less in a 15-minute interval, and the weather data is only measured in .01 kPa increments. I don't know if I should be looking at bigger time intervals, or smaller- I haven't spent much time on the analysis, since I am trying to get some work done today also. I also wonder how much the air-pressure I'm experiencing is different from the air-pressure at the weather station, since I'm going in and out of doors all the time, and as melted_snowball points out, there is a difference between indoor and outdoor air pressure.

I should have also tracked how many hours of sleep I get and when I've taken naps, because I think that is probably a factor as well.
