Is it normal to get a headache while and after thinking intently?
So, basically, yeah. The subject line sums it up.
Lately I've noticed that whenever I do any really in-depth thinking, learning or memorization, I get a headache.
But the thing is, that whenever I get this headache, I know I'm going to be going for the gold. If I'm cooking up an idea while I've got this going on, it's almost always a keeper. If I study something while I've got one of these, I'll pretty much remember every line of what I went over in gruesome detail for months or even years after one single session.
I'm wondering if anyone else gets this? And if so, what do you think the cause might be?
