There are different types of body temperatures and each degree of the body temperature is given a specific name. The following below are the names given to the degrees of temperature:
1. Collapse(hypothermia) : This occurs when the body temperature is below 35 degrees centigrade(95 degree F).
2. Subnormal : Here is when the body temperature is between 35 degrees centigrade to 36.2 degrees centigrade(95 degrees F to 97 degrees F).
3. Normal : The body temperature is between 36.2 degrees centigrade to 37.2 degrees centigrade(97 degrees F to 99 degrees F).
4. Pyrexia : This is when the body temperature is above 37.2 degrees centigrade(99 degrees F).
5. Low: Body temperature between 37.2 degrees centigrade to 38.3 degrees centigrade(99 degrees F to 101 degrees F).
6. Moderate : This is when the body temperature is between 38.3 degrees centigrade to 39.4 degrees centigrade(101 degrees F to 103 degrees F).
7. High : In this case, the body temperature is between 39.4 degrees centigrade to 40.5 degrees centigrade(103 degrees F to 105 degrees F).
8. Hyperpyrexia : This is when the body temperature is above 40.5 degrees centigrade(105 degrees F).
CAUSES OF SUBNORMAL TEMPERATURE
1. Lessened heat production due to starvation
2. Exposure to cold over a long period
3. Shock, haemorrhage and dehydration.
CAUSES OF PYREXIA
The invasion of micro-organisms and inflammation due to any other cause are:
1. Continuous pain
2. Toxic condition
3. Infection caused by micro-organisms like dengue, pneumonia, wound infections.
4. Diseases caused by parasites like malaria, filariasis.
5. Direct interference with the heat regulating centre in the medulla oblongata. Example: Tumour, Head injuries.
PYREXIA EFFECTS ON THE BODY
The signs and symptoms which accompany an elevated temperature indicate its widespread effect on the body in that every system is involved. This is known as the febrile state or state of fever.
Antibiotics and suphonamides drugs can be used to cut short the febrile state.
Nervous system : It causes headache, restlessness, insomnia and delirium.
Muscular system : General aches and pains, feeling of weariness, malaise.
Excretory system : Reduced output of highly coloured urine.
Respiratory system : It increases rate of breathing
Alimentary system : It causes dry mouth and tongue, anorexia, nausea and vomiting, constipation or diarrhea.
Circulatory system : It increases pulse rate.
