At what core body temperature does the body lose its ability to shiver?

The body loses its ability to shiver when the core temperature drops significantly. Specifically, this loss of shivering ability occurs at around 32 degrees Celsius (90 degrees Fahrenheit). Shivering is a crucial physiological response that helps to generate heat and maintain core body temperature in cold environments.

As the body temperature continues to decrease, various thermoregulatory functions become impaired. At 32 degrees Celsius, individuals may start to experience moderate hypothermia, leading to decreased muscle function and coordination, as well as other physiological responses. Therefore, when evaluating the point at which shivering ceases, 32 degrees Celsius or 90 degrees Fahrenheit is the critical threshold.
