Low body temperature can be normal for some patients, or it can signal problems such as diabetes, hypothyroidism, kidney failure or Addison's disease, according to the Riverside Health System. A body temperature is not considered to be dangerously low until it falls below 95 degrees Fahrenheit.
Other conditions that can cause low blood temperature include hypothalamus dysfunction, liver failure or a widespread infection in the body, explains the Riverside Health System. Certain medications, excessive alcohol use and illicit drug consumption can also result in a low blood temperature.
A normal human body temperature ranges from 97.5 to 98.8 degrees Fahrenheit, according to the Riverside Health System. Hypothermia occurs when body temperature dips below 96 degrees Fahrenheit, notes Mayo Clinic.
