Frigophobia is a phobia pertaining to the fear of becoming too cold. Sufferers of this problem bundle up in heavy clothes and blankets, regardless of the ambient air temperature. This disorder has been linked to other psychological disorders such as hypochondriasis and obsessive-compulsive disorder. In a 1975 study among ethnic Chinese in Taiwan, it was noted that frigophobia may be culturally linked to koro. Where that disorder causes male sufferers to feel that their penis is retracting into the body due to an insufficiency of "male element" (or "yang"), male frigophobia sufferers correlate coldness with an over-abundance of "female element" (or "yin").

Frigophobia is defined as a persistent, abnormal, and unwarranted fear of coldness despite conscious understanding by the phobic individual and reassurance by others that there is no danger. It is also known as cheimaphobia or cheimatophobia.
