Brief Answer:
Low body temperature

Detailed Answer:
Hi, thanks for using Healthcaremagic.

Mild reductions in body temperature are often temporary and don't indicate a serious problem or condition. For example, your temperature normally is lower in the morning than in the evening. The most common cause of a lower-than-normal body temperature is exposure to cold. But occasionally, a low body temperature can indicate an underlying problem or condition, such as:
Hormonal disturbances like
Underactive thyroid (hypothyroidism)
Diabetes
Adrenal gland insufficiency (Addison's disease)
Hypothalamus dysfunction

Liver failure
Kidney failure
Widespread infection (sepsis)
Excessive use of alcohol or illicit drugs
A side effect of certain medications, such as phenothiazines, barbiturates, opiates, clonidine, lithium and benzodiazepines

Wish you a good health.
