An abnormally decreased sensitivity to heat or temperature perception

A body temperature significantly less than 98.6°F (37°C).

1. Somewhat warm.
2. Relating to reduction of body heat.

1. A body temperature significantly below 98.6°F (37°C).
2. The condition of having a body temperature substantially below the normal, either as a result of natural causes or artificially induced (e.g. for cardiac surgery).

1. A tentative theory about the natural world; a concept that is not yet verified but that if true it would explain certain facts or phenomena.

4. The condition (in muscle or muscular tissue) of being hypotonic.

1. Having a lesser degree of tension.
2. Having a lesser osmotic pressure than a reference solution, which is ordinarily assumed to be blood plasma or interstitial fluid; more specifically, it refers to a fluid in which cells would swell.
