charge of controlling the body’s temperature.

Heat Related Illnesses
The heart has to work harder, pumping more blood toward the
skin to help with cooling and puts extra stress on the body
 Heat Cramps: As the body overheats, muscles in the
legs, arms, or abdomen can spasm. Feels like charley
horses and can be pretty painful.
 1. Get out of sun
 2. Drink fluids
 3. Stretch or massage muscles
Heat Related Illness
Next Stage:
 Heat Exhaustion: Whole body reacts to heat,
extreme fatigue. May be dizzy, lightheaded,
disoriented.
 1. Get in shade
 2. Rehydrate
 3. Mist with cool water,
cool bath
Heat Related Illness
Final Phase
 Heat Stroke: can be fatal – body can’t regulate body
temperature. The body’s temperature may rise to 105
degrees F. Symptoms are extreme confusion and
shock.
• Call 911
• Cool body down
until help arrives
Cold Related Illnesses
 Hypothermia: when body temperature drops
below normal; feel drowsy or exhausted. May shiver,
stumble, speak slowly.
Cold Related Illness
 Frostbite – blood flow slows and ice crystals form.
Nose, toes, fingers, and ears are at highest risk.
Happens with lengthy exposure to cold air, wet, or
windy conditions.
To Prevent/Treat Cold Related Illness
1. Wear multiple layers, gloves (mittens are better), hat
2. Know the signs: skin first pale and numb; then hard

and frozen; blisters, blue, or black skin.
Thaw with warm, not hot water, or warm compresses.

Take shelter in a sturdy building.
Stand under shortest tree if in woods, not an isolated
tree, near a fence, or in a shed.
Don’t use phone unless emergency – phone lines can
conduct electricity.
Unplug appliances.
Stay away from the fireplace.
Get out of boats, don’t take a
bath/shower – water can conduct electricity.
Tornadoes
 Watch – conditions are right for a tornado, keep alert.
 Warning – a tornado has been sighted; if heading
your direction, take cover.
1. Seek shelter in a basement if possible
2. Stay in center of the ground floor, in room with no
windows if no basement.
3. If outside, go in a low ditch/ravine

leading cause of death.
Wear life jackets when boating or skiing
Don’t dive in water unless you are sure it is deep
enough and safe.
Avoid alcohol and other drugs that could impair your
ability to swim or your judgment.
Don’t swim alone and take classes if you don’t know
how to swim.
If you fall into really cold water, body shuts down and drowning
victims may survive longer than if the water is warm. People with
more insulation on their bodies will also survive longer in cold
water before hypothermia sets in.
