ORIGINAL: DoraExplorer every time, about an hour afterwards, I've got this horrible horrible headache. I've never suffered from migraine, and from what I read about them this isn't one, but I do need to lay down for a while because I can't do anything else; it lasts for a couple of hours and then abates. It does appear to be a physiological response. I have created the following hypothesis to explain it. Firstly, it is a fact that headaches are often caused by a widening of the bloodvessels in or on the brain. Apparently in your case this is not caused by the bloodvessels themselves relaxing and widening, but because they are forced to widen by a large amount of blood that is forced into them. This blood must be coming from another compartment where it is forced out about one hour after your session. I expect this other compartment to be the skin and that during your session the bloodvessels in your skin become enlarged, fill with blood en colour your skin red. When the blood vessels in your skin recuperate about one hour after your session, they tighten up and force the blood they contain back into the body. Apparently, the bloodvessels in the body during the session are forced to tighten up to push their blood into the skin, but they take much longer to revert to normal conditions. Therefore, there is no room in the bloodvessels of the body for the blood returning from the skin one hour after the session. This blood has nowhere else to go but into the bloodvessels of the brain, causing the headache. Hypothetically, the bloodvessels in the bodycore will be stimulated to widen when you consume something cold, thus drawing warm blood into them to negate the effect of the cold. So you may try to consume some icecream half an hour after your session and before and during your headache. In theory it should make a difference.
