  Torpor - Wikipedia, the free encyclopedia
Torpor is a state of regulated hypothermia in an endotherm lasting just a few hours.
Torpor is often used to help animals survive in a cold climate, since it allows the organism to save the amount of energy that would normally be used to maintain a high body temperature.
Torpor is alternately used as a reference to any non-physiological state of inactivity.

 § 44. turgor / torpor. 4. Science Terms. The American Heritage Book of English Usage. 1996
While many of the events we think of as stress-producing are the result of human-human interaction, so-called natural stresses such as heat or cold also trigger a variety of symptoms, or responses in living organisms.
In contrast to this concept of pressure or tension, torpor, from Latin torpere, “to be stiff,” is a metabolic response exhibited by some mammals.
Thus, an animal is said to be in a state of torpor when it hibernates to avoid the stresses of cold and, perhaps, food shortages or when it estivates to avoid excessive heat or drought.

 Interesting Hamster Studies   (Site not responding. Last check: 2007-10-17)
The difference between hibernation and torpor is how long the sleep times are and how much the animal's bodies slow down.
So, in the scientists conclusion they stated that they were correct in hypothesizing that furless hamsters would not need to induce torpor because it would take too much energy to rewarm themselves after the torpor, thus taking away the energy saving benefits from the process.
This experiment was a basic study on the substances involved or present in or during torpor such as serum lipids, glucose or PDH on brown adipose tissues, heart, brain and kidney muscle and affects on respiratory quotient.

 STUDENT ABSTRACTS
Torpor is a hypo-metabolic response in mice and other small rodents induced by low ambient temperature and food scarcity.
Upon fasting at 16º C, the majority of the control mice entered torpor, whereas the majority of the MSG treated animals did not enter torpor, indicating the requirement of the ARC in mediating the onset of torpor.
However, ghrelin did not induce torpor in MSG treated mice, suggesting that the effect of ghrelin on torpor is mediated through the ARC.

This is the third hindrance, sloth and torpor, thina midha in Pali.
Practice itself can cause sloth and torpor sometimes, if you are doing practice with some restless goal or strong need, which probably gives you unrealistic expectations of what is going to happen as a result of practice, and unrealistic demands on yourself.
The antidote to sloth and torpor is faith in practice, the abiding understanding that practice is a necessity.
