Here’s an overview of some things that can cause chills but no fever: 1. Being in a Cold Environment ... Cohan says dehydration can cause your body temperature to drop, which might make you feel ...
In heat exhaustion, the core body temperature rises to between 37 °C and 40 °C (98.6 °F and 104 °F). To dissipate heat, blood flow to the skin can increase up to 8 liters per minute, accounting for a significant proportion of the cardiac output. This increase in peripheral circulation leads to a reduction in central blood volume—the ...
The human body always works to remain in homeostasis. One form of homeostasis is thermoregulation. Body temperature varies in every individual, but the average internal temperature is 37.0 °C (98.6 °F). [1] Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate.
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.

Bathing in tepid or cool water, or even just washing the face and other exposed areas of the skin, can be helpful. With fever, the body's core temperature rises to a higher temperature through the action of the part of the brain that controls the body temperature; with hyperthermia, the body temperature is raised without the influence of the ...
