Hypoventilation syndrome. Congenital central hypoventilation syndrome (CCHS) is a rare disorder of respiratory control with autonomic nervous system dysregulation (ANSD).
Frost forms in much the same way as dew forms. Frost usually forms when a surface cools through loss of infrared radiation to a temperature which is colder than the dewpoint of the air next to the surface, AND the temperature of that surface is below freezing (32 deg F, or 0 deg.C).The source of this moisture is water vapor contained in the air.rost forms in much the same way as dew forms.

A: Chemists at the University of Utah discovered that ice forms at temperatures as low as minus 55 degrees Fahrenheit, according to a Science Daily article. Prior to this discovery, scientists believed ice formed exclusively at 32 degrees Fahrenheit.
