Your body temperature is 33.3°C (91.9°F)?
The normal human body temperature oral (under the tongue) should be about 36.8°C (98.2°F), while the normal internal human body temperature (rectal, vaginal) should be at about 37.0°C (98.6°F).
Values of atleast 0.5°C above said temperature can be considered fever while temperatures of 1-2°C below normal temperature are known as 'Hypothermia' (body temperature too low).
Your body temperature of 33.3°C (91.9°F) is too low (Hypothermia).
Hypothermia can occur for several reasons. Hypothermia, or low body temperature, may happen after spending prolonged periods of time in very cold temperatures. Once the human body becomes too cold to regulate itself, its temperature drops, resulting in hypothermia. Hypothermia, however, can also be a symptom of the diseases or disorders such as diabetes, Addison's disease, hypothyroidism, drug abuse, kidney or liver failure, infection, sepsis, shock, cancer, stress, and insomnia. It may also be a side effect from a medication.
While shivering and being cold is one of the most obvious symptoms of hypothermia, there are others to look out for. Shivering is typically accompanied by some degree of teeth chattering and goose bumps as well. Other symptoms may include slow heartbeat, dilated pupils, shallow breathing, weak pulse, drowsiness, purple extremities, lack of coordination, slurred speech, and tiredness.
