out in the cold
[Middle English, from Old English ceald.]
coldly cold'ly adv.SYNONYMS cold, arctic, chilly, cool, frigid, frosty, gelid, glacial, icy. These adjectives mean marked by a low or an extremely low temperature: cold air; an arctic climate; a chilly day; cool water; a frigid room; a frosty morning; gelid seas; glacial winds; icy hands.
ANTONYM hot
Medically termed a coryza or rhinitis, a cold in the head is caused by a viral infection. There is some concern that exercising during a viral infection can worsen the disease and may, albeit rarely, lead to myocarditis (inflammation of the heart muscle which can in some cases cause sudden death). Studies on the effects of exercising during a viral infection are inconclusive, but it is generally agreed that it is safe for a person with a mild cold to continue with light to moderate levels of physical activity, provided the cold is not accompanied by a fever. A person with a body temperature higher than 38°C should not exercise.

A virus infection in which blockage and inflammation of the nose (rhinitis) and sinuses are prominent symptoms. Although many athletes train and even compete with a mild cold, it is wise to avoid all strenuous activity during the feverish stage of a cold because there is a danger that the virus will affect the heart (see myocarditis). Many over-the-counter cold cures contain stimulants, which constrict blood vessels in the upper respiratory tract and nose. Some of these medications contain substances on the World Anti-Doping Agency's 2005 Prohibited List. No medication should be used by a competitor without first checking with doctor or pharmacist that the product does not contain a drug on the Prohibited List.

1. an acute disease of the upper respiratory tract characterized by cough, sneezing, running at the eyes and nose and mild fever, similar to the common cold of humans, occurring in captive primates.
2. a relatively low temperature; the lack of heat. A total absence of heat is absolute zero, at which all molecular motion ceases. See also hypothermia.

Cold refers to the condition or subjective perception of having low temperature. A cold body is often described as the opposite of hot, or as having less heat, although the latter use of "heat" would be incorrect in the context of physics, as heat refers to the transfer of energy between bodies, which do not "have" heat themselves.
A lower bound to temperature is the absolute zero, defined as 0 K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to −273.15 °C on the Celsius scale, −459.67 °F on the Fahrenheit scale, and 0 °R on the Rankine scale.
Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in this classical sense. The object would be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because of the uncertainty principle.

Mammals have an endothermic ("warm-blooded") physiology. Therefore they have a perception of thermal comfort that is centered around their body temperature. Their thermal comfort is dependent upon their metabolism and environmental surroundings, and is affected by heat conduction, convection, radiation, and evaporative heat loss. Thermal comfort is maintained when the heat generated by their metabolism is allowed to dissipate, thus maintaining thermal equilibrium with the surroundings. When this equilibrium is not maintained due to excessive heat loss, then they will perceive the feeling of being too cold, and in varying degrees of discomfort depending upon how far this equilibrium is skewed.[citation needed]
Cooling refers to the process of becoming cold, or lowering in temperature. This could be accomplished by removing heat from a system, or exposing the system to an environment with a lower temperature.
Fluids used to cool objects are commonly called coolants.
Air cooling is the process of cooling an object by exposing it to air. This will only work if the air is at a lower temperature than the object, and the process can be enhanced by increasing the surface area or decreasing the mass of the object.
Another common method of cooling is exposing an object to ice, dry ice, or liquid nitrogen. This works by convection; the heat is transferred from the relatively warm object to the relatively cold coolant.
Laser cooling and Magnetic evaporative cooling are techniques used to reach very low temperatures.
