ANIMAL HEAT 13 



the red corpuscles of the blood absorb the oxygen, which 

 we inhale, and carry it to all parts of the body, to burn up 

 waste material. Thus it is that all parts of the body are warm. 

 If, however, the circulation is poor, so that this destruction 

 of waste is not complete, we have cold feet, cold hands, and, 

 in very severe cases of poor circulation, bad chills. 



The temperature of human beings is ninety-eight and four 

 tenths degrees F. No matter what the weather may be, the 

 temperature of a healthy person does not vary more than one 

 half of a degree. A variation, upward or downward, of a few 

 degrees from the normal temperature will result in death. 

 Thus it is that fevers and chills are weakening to the consti- 

 tution, and, unless properly taken care of, may be fatal. 



If we become cold, we may exercise and increase the circu- 

 lation, thereby increasing the combustion throughout the 

 whole body, and maintaining the temperature which would 

 otherwise be lowered. Or, if we desire, we put on heavier 

 clothes, which serve to keep in the heat of the body. If we 

 become warm, we remove some of our clothing. 



In Section 89, Carbon Dioxide, this matter will be considered 

 further.
