At what core temperature does the shift occur from mild to moderate hypothermia?

The shift from mild to moderate hypothermia occurs at a core temperature of around 90 degrees Fahrenheit. At this temperature, physiological changes become more pronounced, and the body’s ability to regulate temperature and maintain normal functions decreases significantly. Mild hypothermia typically presents with symptoms such as shivering, confusion, and slight coordination issues, while moderate hypothermia can lead to more severe symptoms, including a marked drop in muscle function, lethargy, and a decreased heart rate, which are important factors to recognize in a search and rescue scenario. Understanding this transition is crucial for responders to provide appropriate care and interventions based on the severity of the hypothermia.
