What is one of the 4 measurements the WBGT takes into account for a heat index?
Humidity, UV Rays, Wind speed, Air temperature
This condition involves involuntary muscle spasms caused by an imbalance of water and electrolytes, specifically sodium
Muscle Cramps
What does UVR stand for?
Ultraviolet Rays (Radiation)
Using the "flash-to-bang" method, how many seconds are equal to one mile of distance?
5 seconds
At what percentage of relative humidity does sweat not evaporate from the body?
75%
This occurs when a person collapses or loses consciousness due to hypotension (low blood pressure) and the pooling of blood in the extremities
Heat Syncope
This cold-related condition affects only the skin and subcutaneous tissue; the skin feels hard but blisters may form during rewarming
Frostbite
After the last lightning strike is seen or thunder is heard, how long must you wait before returning to the field?
30 minutes
This cooling method is the most effective for dissipating heat, but it requires sweat to actually leave the skin surface as a vapor
Evaporation
Characterized by excessive dehydration, dizziness, and cognitive loss, this condition may require several days for the victim to recover
Heat Exhaustion
What does SPF stand for?
Sun Protection Factor
What is one long term effect of overexposure to the sun and UV Rays?
Premature aging or skin cancer
This mode of heat dissipation involves direct contact with a cooler object, such as a cold, damp towel on the carotid artery
Conduction
This is a life-threatening emergency where the body is unable to regulate its own temperature and the core temperature rises to 104° or higher
Heatstroke
According to the "rule of thumb," if you use SPF 15, how much longer can you theoretically stay in the sun compared to having no protection?
15 times longer than if without
True or false - Dressing in thin layers is better way to participate in activities during the cold than one heavier layer.
True
Name the four modes the body uses for cooling purposes.
Conduction, Convection, Radiation, and Evaporation.
True or False: When treating a heatstroke victim, replacing body fluids is the first and most important priority
False
Shivering is a natural defense against the cold, but it typically stops when the body's core temperature drops below this degree.
90 degrees
This is the term used for when an athlete's body is used to the weather it will be competing in
Acclimated
