Looks pretty darned quiet to me right now:
You can find that here, along with other measures of space weather.
By the way, cosmic rays and solar activity are two entirely different things. Cosmic rays originate from outside of our solar system. The flux of cosmic rays is relatively constant.
As for your question about stress, indeed, I just experienced some added stress because people propagate stupid emails like that.
To be fair, I did in fact experience stress and headaches due to solar activity back in 2003. Right around Halloween it looked like this (note that these are log plots):
At that time I was the mission manager responsible for MER-A, also known as Spirit, in cruise on its way to Mars. This was the largest solar event that had ever been seen at that time, and so it wouldn't be MER if we hadn't been hit by it. As you can see, the event was, quite literally, off the chart. Both MER-A and MER-B were disabled by the event, losing their ability to track stars, and therefore unable to do turns or conduct maneuvers. Fortunately they were spinning spacecraft and were able to maintain attitude while they weathered the storm. In the meantime, we on the ground had no idea how long the storm would last, whether the star scanners would ever work again, and whether we would be able to get those spacecraft to their precise entry points at Mars.
So yes, solar activity can cause stress and headaches, if you happen to be a spacecraft operator, or you live in space. Or possibly, if you happen to operate electronic communication systems on the ground that are susceptible to space weather.
