The real, emerging science, as the Heartland publications indicate, is that the feedbacks are more likely to be offset by negative feedbacks, resulting in a much smaller net temperature change.
However, by making something out of ions that are bulky and asymmetrical (they have names such as 1-butyl-3-methylimidazolium and hexafluorophosphate, which are as complicated as the ions they represent), the attractive electrical forces can be kept so far apart that the resulting substance is a liquid at room temperature.
Research has shown that the body's temperature tends to rise by a few degrees in the afternoon, warming the muscles and connective tissues and resulting in a slight improvement in your performance capabilities.
