Self-contained breathing apparatus pressure changes with ambient temperature. As temperature decreases, the pressure inside the cylinder decreases. The relationship between the temperature and the pressure of a gas is defined by the formula "PV" = "nRT". (See Universal gas constant.) What is particularly important to understand from the formula is that the temperature is in kelvins, not degrees Fahrenheit. Consider the freezing point of water at 32 °F (0 °C, 273.15 K) and compare it to 96 °F (35.6 °C or 308.71 K; normal human body temperature is 37 °C). While 96 is arithmetically three times 32, the difference in temperature from a
Wilson's temperature syndrome associated with the "syndrome". Wilson's temperature syndrome Wilson's (temperature) syndrome, also called Wilson's thyroid syndrome or WTS, is an alternative medicine concept which attributes various common and non-specific symptoms to low body temperature and impaired conversion of thyroxine (T4) to triiodothyronine (T3), despite normal thyroid function tests. E. Denis Wilson, a physician who named the syndrome after himself, advocates treating these symptoms with sustained-release triiodothyronine. Wilson's syndrome is not an actual medical condition, and there is no scientific evidence supporting Wilson's claims. The American Thyroid Association (ATA) describes Wilson's syndrome as at odds with established knowledge of thyroid function. The
