A person who feels cold more frequently than warm is said to have a frigid disposition. Even when those around them are warm or the temperature is higher, persons with frigid personalities often remain cold.
There is evidence that some nerve cells react to things other than temperature when producing the experience of being cold, according to a 2004 study by researchers at the University of Florida that was published in the Journal of Neuroscience.
Even if the outside temperature may feel pleasant, a cold-natured person’s body contains biochemicals, hormones, and proteins that contribute to their perception of being cold. This explains why a person’s temperament can occasionally be affected by things like sadness or menopause.
