No, the human perception of temperature thing is a myth. Originally 0F is the freezing temperature of a brine solution, and 90F was Fahrenheit’s estimation on the average human body temperature, and then the scale was adjusted so that it fit in better with Celsius reference points (freezing/boiling points of water).
