2017 has been a wild ride. And in true “what the heck is going on?” fashion, 2017 is exiting stage left with a bang. That’s right, Mercury will remain in retrograde through Dec. 22. Mercury retrograde simply means that Mercury is rotating faster than Earth (and thus, looks like it's going "backwards" in its orbit from our perspective), but this optical illusion is often blamed for all sorts of cosmic confusion for us poor Earthlings.
According to astrologers, Mercury retrograde has been said to cause a bunch of trouble when it comes to communication issues and technological headaches. But some people are wondering if Mercury retrograde can cause physical headaches, too. The short answer is, well, no. You may have noticed an uptick in the amount of headaches you’ve experienced since Mercury retrograde began on Dec. 3, but Mercury retrograde isn’t to blame — at least not directly. No matter how frustrating your technological issues are during this time, Mercury retrograde definitely cannot cause your headaches. However, the stress from having your computer crash right before your finals — one common reported Mercury Retrograde symptom — very well could. There are also a number of potential headache causes related to the time of year, or other, more general factors that could account for an increase in headaches. Once you identify what’s really causing your head to throb, you can take steps to avoid or counter it.
