2. Weather-Related Risks
Hot Weather-Related Risks
Dehydration- excessive loss of water
from the body
Poor air quality
3. Hot Weather-Related Risks
Overexertion
Overworking the body
Heat exhaustion
Overheating the body that results in
cold, clammy skin and symptoms of
shock
Caused by overexertion in a hot,
humid atmosphere
4. Hot Weather-Related Risks
Heat cramps
Muscle spasms that result from a loss
of large amounts of salt and water
through perspiration
5. Hot Weather-Related Risks
Heatstroke
A condition in which the body loses
the ability to rid itself of excessive heat
through perspiration
Causes hyperthermia (increase in
body temperature)
May have difficulty breathing or may
suddenly collapse
6. Cold-Weather Health Risks
Wear 3 layers of clothing
Make sure the layers keep out
moisture
70% of the body’s heat is lost through
the head, so a hat is a must
Frostbite and hypothermia are two
specific health risks to keep in mind
7. Cold-Weather Health Risks
Frostbite
A condition that results when body tissues
become frozen
Cover all exposed skin
• Ears, face, feet, and fingers
An early sign of frostbite is frostnip
• A whitening of the skin of the toes, fingers, nose,
or ears
Go indoors immediately if any area of the
body has a lack of feeling due to the weather
8. Cold-Weather Health Risks
Hypothermia
A condition in which body temperature
becomes dangerously low
Body loses the ability to warm itself
As body temperature drops, the brain
cannot function and body systems
begin to shut down
9. Minor Injuries
Muscle cramp
Spasm or sudden tightening of a muscle
Happens when a muscle is tired,
overworked, or dehydrated
Strain
Condition resulting in damaging a muscle or
a tendon
