Body heat

Body heat gain or loss The positive or negative change in the heat content of the human body caused by an imbalance between heat production and heat loss. 

Body heat storage The heat stored in the body due to metabolism. 

Maximum body heat storage (Q, 3, ) The maximum value of the body heat gain achievable by the subject such that the resulting increase in body core temperature does not induce pathological effect, in W h nr-. 

Metabolic heat production The production of body heat due to the intake of oxygen and carbohydrates. 

Cold stress Physiological stress on the body created by excessive loss of body heat. 

Under certain conditions, such as hyperbaria,airway heat losses can account for a considerable percentage of total body heat production (in some cases > 100%). Normally these threats are ameliorated by rapid moderation of inspired air temperature and humidity by exchanging heat and water vapor between the mucus and airstream in the upper airway. Recovering much of the heat and water vapor contained in expired air minimizes heat and water losses to the ambient environment and aids in whole-body thermoregulation. 

Diaphoretic. Because it promotes perspiration by relaxing the pores, elder is a traditional remedy to help the body release toxins through the skin. It increases blood circulation and body heat near the surface of the skin. It has been used to treat blemishes, acne, herpes, psoriasis, measles and chicken pox. Parts used flowers, berries, leaves. 

Nahuatl, edible root), is an important contribution to world nutrition in addition to have been used by the native population as a cold nature remedy to reduce excessive body heat (A The Latin description in this illustration from the Badianus Manuscript reads Contra cordis calorem, for heat in the heart Libellus de Medicinalibus Indorum Herbis, 1552. Fol. 28v. CONACULTA-INAH-MEX, with permission of the Instituto Nacional de Antropologia e Historia , Mexico). 

To release energy, the electrons can be removed from glucose and used to create ATP, a molecule that supplies a cell s short-term energy needs. This latter occurs in a series of reactions known as respiration. (Body heat is a by-product of these reactions.) The most efficient respiration reactions are those that use oxygen to accept the electrons removed from glucose. Thus respiration is the reverse of photosynthe- 

Hyperbolic expansion The expansion of a fluid according to the law pV = Hypothalamus The temperature control center at the base of the brain, which regulates body temperature. Hypothermia The physiological state resulting when the deep core body temperature drops below 35 C. It results in vasoconstriction and shivering in an attempt to conserve body heat. 

Native to tropical America, sweet potato (I. batatas) is a perennial morning glory vine that has been cultivated for over 5,000 years for its edible tubers in Mexico, Central and lowland South America, and the West Indies. Today, sweet potato is cultivated around the world, especially in developing countries (Plate 4). A decoction made from the leaves of this plant is used in folk remedies as a gargle to treat mouth and throat tumors, and poultices are prepared for inflammatory tumors (64). In Mexico, leaf decoctions are considered to be of cold nature , to reduce excessive body heat, contemporarily defined as such illnesses as diarrhea, dysentery, heart disease, stomach distress, fever, and gastrointestinal infection. In Chinese traditional medicine, the tubers have been used as a medicinal herb to eliminate secretion in perceived abnormal quantities of blood or other body fluids (79).
