Scientists have found yet another reason to be glad it’s Friday. A new study found that the feeling we all have from time to time -- that the work week gives us a headache -- might not be all in our minds.

Sparked by curiosity about what online behavior could tell them about pain, researchers from Boston Children’s Hospital and Harvard Medical School probed search engine queries and Twitter posts that mentioned “migraine” or “headache.” What they found, in a study published online in the journal Cephalalgia, is that headache mentions peaked on weekdays, hitting their high early in the week and receding on Fridays.
