Physics:Thermophobia
Thermophobia (adjective: thermophobic) is intolerance for high temperatures by either inorganic materials or organisms.[1] The term has a number of specific usages.
In pharmacy, a thermophobic foam consisting of 0.1% betamethasone valerate was found to be at least as effective as conventional remedies for treating dandruff. In addition, the foam is non-greasy and does not irritate the scalp.[2][3] Another use of thermophobic material is in treating hyperhydrosis of the axilla and the palm: A thermophobic foam named Bettamousse developed by Mipharm, an Italian company, was found to treat hyperhydrosis effectively.[4][5]
In biology, some bacteria are thermophobic, such as mycobacterium leprae which causes leprosy.[6] Thermophobic response in living organisms is negative response to higher temperatures.
In physics, thermophobia is motion of particles in mixtures (solutions, suspensions, etc.) towards the areas of lower temperatures, a particular case of thermophoresis.[7]
In medicine, thermophobia refers to a sensory dysfunction, sensation of abnormal heat, which may be associated with, e.g., hyperthyroidism.[7][8]
