"Blood Pressure" is about the pressures humans are constantly under in their daily lives, from the home to the religious environment. In our interview with Mutemath drummer, Darren King
, he revealed that he wrote the track's foundations: "That one started with me. I wrote the 'Why can't you be more like your older brother' and the chorus of 'Blood Pressure,' but I had very few lyrics. I don't consider myself a lyricist. I just try. I'll write pages and pages and all I'll get from it is one little line."
King added that it was Mutemath front man, Paul Meany, who helped to develop the track's religious connotations: "Paul really elaborated on that idea and turned it into something that was not just about family pressure and pressure to live up to your parents' expectations or to compare yourself to your siblings' success, but it also became about the blood that the church talks about, and the pressure of living up to the verse in the bible where Jesus says, 'Greater works than me shall you do.'"
