Another theory suggests that cold ears may be related to neurological factors. The ear is innervated by the trigeminal nerve, which is responsible for regulating blood flow and temperature sensation. Dysfunction or irritation of this nerve could potentially lead to abnormal sensations, including coldness, in the ear.
