A temperature of 41 or 42 C. is quite alarming, and if it remains long at this point death is sure to occur. 136. Regulation of Temperature.--The heat generated in the body passes off largely through the skin. This is accomplished in three ways: by radiation, conduction, and evaporation. The air is heated by coming in contact with the skin, and various substances which come in contact with the body, if they are of a lower temperature, gain heat by conduction. Evaporation of the perspiration also lowers the temperature. The blood is also cooled during its passage through the lungs, as is evinced by the fact that the exhaled air is usually warmer than the surrounding atmosphere. In the cold season, we make our own temperature by the use of wraps, which serve to protect the body from the cold air and to retain the heat generated, and by stoves and other kinds of heating apparatus. The body is also able to withstand the effects of extreme heat. Perspiration pours out freely when the temperature of the atmosphere reaches a high point, and evaporation keeps the body cool. In the hot countries the temperature often reaches 50 C, yet the bodily temperature is not raised above the normal. 137. Effects of Alcohol on Vital Heat.--Alcohol, generally speaking, lowers the temperature of the body. If the quantity taken be small, there may be a trifling rise of temperature due to the increased circulation of the blood. This effect is transient, the-heat of the body quickly returning to the normal. It is this effect of alcohol in small doses that has given rise to the erroneous belief that a drink of whisky or brandy will "keep out...
