To cool in a refrigerator but not freeze.
A feeling of cold with shivering and pallor, accompanied by an elevation of body temperature in the interior of the body. Often an early symptom of an infectious disease caused by invasion of the blood by bacterial toxins.
A short illness causing a feeling of being cold and shivering, usually the sign of the beginning of a fever, of flu or a cold.
Involuntary, rapid contraction of muscle groups (shivering; accompanied by the sensation of cold, or the sensation of being cold without shivering. It maybe caused by a rising fever associated with an infection, a hypersensitivity reaction to drugs or blood transfusions, exposure to cold temperatures, or a neuroendocrine disturbance in the temperature-regulating centers of the hypothalamus. Severe chills accompanied by violent shaking of the body are called rigors.
To reduce the temperature to a moderately low degree without reaching the freezing threshold.
A trembling episode accompanied by chattering teeth, pallid complexion, raised hair follicles, and a sensation of coldness. Chills often occur before the onset of a fever. Recurrent or intense shivering indicates a potentially grave ailment.
A feeling of cold and the shivering that occurs with a fever. There is no medical word which is more popularly used and with less scientific reason. Almost the first thing that most patients blame for whatever is wrong with them is “catching a chill.” It all harks back to the Middle Ages when there was no scientific explanation for disease and no knowledge of their infective origin from bacteria and viruses; thus the cold feeling experienced with the arrival of a raised temperature not only became a symptom, it also became the pathological explanation. It is true that being subjected to chilling conditions, such as standing in a cold draft, may temporarily lower the resistance of the body, so that germs, already present in the body, find an opportunity to attack and cause illness. In most cases this popular expression really means that the person has contracted a cold in the head.
