In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [3] [10] The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [2]
While some people think of these averages as representing normal or ideal measurements, a wide range of temperatures has been found in healthy people. [5] The body temperature of a healthy person varies during the day by about 0.5 °C (0.9 °F) with lower temperatures in the morning and higher temperatures in the late afternoon and evening, as ...
There is an ongoing medical debate over what is the optimal level of blood pressure to target when using drugs to lower blood pressure with hypertension, particularly in older people. [ 13 ] Blood pressure fluctuates from minute to minute and normally shows a circadian rhythm over a 24-hour period, [ 14 ] with highest readings in the early ...

The capacity to regulate body temperature may also have to do with brain chemicals such as serotonin and dopamine, which are generally lower in the brains of people with these disorders, experts said.
A hypertensive emergency is not based solely on an absolute level of blood pressure, but also on a patient's baseline blood pressure before the hypertensive crisis occurs. Individuals with a history of chronic hypertension may not tolerate a "normal" blood pressure, and can therefore present symptomatically with hypotension , including fatigue ...
