 Hypothermia: A decrease in the core body
temperature to a level at which normal
muscular and brain functions are impaired.

• Mild Hypothermia
– Core temperature 98.6 - 96 degrees F

– Shivering - not under voluntary control.

– Shivering - not under voluntary control.
– Can't do complex motor functions (ice climbing
or skiing) can still walk & talk.

• Which is not true of mild hypothermia?
A.) Shivering - not under voluntary control.
B.) You can still do complex motor functions.
C.) Impaired Judgement.
D.) You can still walk and talk.

• Moderate Hypothermia –

– Core temperature 95 - 93 degrees F

– Dazed consciousness.

– Loss of fine motor coordination - particularly in
hands - Can't zip up parka, due to restricted
peripheral blood flow.

– Slurred speech.

– Slurred speech.
– Violent shivering.

– Slurred speech.
– Violent shivering.
– Irrational behavior - Person starts to take off
clothing, unaware she/he is cold.

• Severe Hypothermia - core temperature 92 - 86
degrees and below (immediately life threatening)
– Shivering occurs in waves, violent then pause, pauses
get longer until shivering finally ceases.
– Person falls to the ground, can't walk, curls up into a
fetal position to conserve heat.
– Muscle rigidity develops - because peripheral blood
flow is reduced and due to lactic acid and CO2 buildup
in the muscles.
– Skin is pale.
– Pupils dilate.
– Pulse rate decreases.
– At 90 degrees the body tries to move into
hibernation, shutting down all peripheral blood flow and
reducing breathing rate and heart rate.
– at 86 degrees the body is in a state of "metabolic
icebox." The person looks dead but is still alive.

• Please place the arrow where a human may
become moderately hypothermic.

• Answer! 94 Degrees Fahrenheit or 34.44
Degrees Celsius

• Place the yellow line where a humans core
temperature should be at normal range.

• Answer: 98.6 degrees F,
• 37 degrees Celsius

 Hyperthermia: Having a body temperature
that is too high, causes heart failure, among
other problems and death.

• Heat Exhaustion.
– What are some symptoms?
Start

– Profuse sweating and high temperature.
Working in sun and warm temperatures
Start

– What are some symptoms?
Next

– Headache, sweating stops, hot dry skin,
feeling faint.

– How can you get it?
Next

– Labor / hard work during high temperatures.
– Also wearing excessive layers when it is warm.

• Heat exhaustion warning signs.

– Abnormally high temperature.

– So hot you might collapse.

– Appear pale.

– Appear pale.
– Sweating profusely.

• Which two are not heat exhaustion
warning signs?
A.) Abnormally high temperature.

– What should you do to prevent heat exhaustion?
Next

– Drink lots of water, seek shade and cooler
temperatures, don’t work when it is too hot!

• Tips to avoid heat exhaustion and heat
stroke, aka hyperthermia.
– Be smart about when you are going to be
active, high noon on the hottest day .
– Know the weather and heat index.
– Drink lots of water / rehydrating fluids.
– Seek shade, and wear loose fitting clothing.
– Take rest breaks (rehydrate)
– Place cool damp towels on forehead.
– Don’t drink alcohol.

• Seek medical attention if needed. To cool
down if you have heat exhaustion…

• Never leave a baby or pet in a car with the
windows up! Not even for a minute!
– Even with the windows down, it is not a safe
practice.
– Hundreds die every year.

– Even with the windows down, it’s not a safe
practice.
– Hundreds die every year.

– Hundreds of pets die every year.

• Put the purple arrow where a human may
become moderately hyperthermic.

• Answer! Hyperthermia occurs when your
body temp is 37.5–38.3 °C (100–101 °F)

• Answer! Life threatening occurs when
your body temp is 40 °C (104 °F)

• Again, organisms have a range of
tolerance, for humans, your body temperature
should be close to 98.6 degrees F, or 37
degrees Celsius.
