Normal Core Body Temperature
The normal core body temperature is different for every person and ranges
between 36 and 37.5 degrees Celsius.
Changes in the environment and conditions affect a persons core body
· extreme climates (very hot or very cold)
· strenuous exercise
· Changes in oxygen levels for long periods of time (high altitudes and
Some organisms have adapted to living in different climates.…read more
Heat stroke is where the body cannot lose body heat fast enough. If your core
body temperature rises above 42 degrees Celsius affect the hypothalamus which
helps to control the core body temperature, the body temperature then rises out
of control. If the core body temperature rises above 43.5 degrees Celsius then
Symptoms of Heat Stroke you will die. Causes
Hot, dry skin Sweating stops
Rapid pulse rate Dehydration, stress,
increased metabolic rate
Dizziness and confusion Nerve cell damage in the
To treat heat stroke you need to cool the patient. You have to do it very quickly
but not to quickly you can do this by:
· Sponging them with water.
· Wrapping them with wet towels.
· Using a fan.
· Putting ice in their armpits and groin.
You must NEVER throw cold water over the patient because this will make the
body think that it is cooling down too quickly so all the blood will run to the brain.
This can be fatal.…read more
Hypothermia is when the core temperature of the body falls below 35 degrees
Celsius. The body's heat cannot be replaced as fast as it s being lost.
Core Body Temperature What Happens
Below 35 degrees Celsius Shivering, confusion,
drowsiness, slurred speech,
loss of coordination
30 degrees Celsius coma
28 degrees Celsius Breathing stops.
To treat hypothermia you need to heat the patient from the inside because if you
heat their skin then blood flow to them will increase and they will lose even more
heat. So you need to:
·Insulate them (especially their head, neck, armpits and groin)
· Handle them gently to keep blood flow to the limps low
· Warm them gently with warm towels
· Give them warm drinks
But DO NOT:
· Give them food (as digesting food lowers metabolic rate) or alcohol
· Use hot water bottles…read more
