I have always had a low body temperature. Same for my sister and mother. The typical is 96.5 – 96.7 for me. One terrifying night I awoke to a 95.4 degree temperature. I really thought I might die that night. My husband helped me into a warm bath and I eventually made it back to my “normal”. I couldn’t stop shivering and chattering my teeth. That has only happened once and it was a few years ago. I have no idea what triggered it.
