About the <strong>Helmet</strong> Heads<br />

• Plan for today:<br />

• Use science to evaluate the common<br />

reasons people don’t wear helmets

Myth # 10<br />

<strong>Helmet</strong>s Aren’t Cool


The Myth<br />

The Details<br />

Wearing a helmet makes me look like a novice.<br />

The Reality<br />

As a patroller / instructor / employee, you are a<br />

role model.<br />

Your example can lead to increased helmet use<br />

and fewer injuries in kids and other guests.

Myth # 9<br />

<strong>Helmet</strong>s Are Expensive Fashion Statements


The Myth<br />

The Details<br />

The cost of helmets cannot be justified.<br />

The Reality<br />

<strong>Helmet</strong> use reduces healthcare costs, hospital<br />

length of stay, and deaths.


The Science<br />

23% higher healthcare costs for un-helmeted (vs.<br />

helmeted) motorcycle accident victims<br />

(Annals of Emergency Medicine)<br />

Seven seasons of skier/snowboarder fatalities:<br />

Predominant cause of death: head trauma<br />

<strong>Helmet</strong> use by those fatally injured: 0%<br />

(Journal of Trauma)


Air medical transport<br />

$1500 per hour<br />

Average ICU stay: 4.3 days<br />

$3500 per day<br />

CT Scan: $1700<br />

MRI: $3500<br />

Emergency Craniotomy<br />

$525,000

Myth # 8<br />

<strong>Helmet</strong>s Block Sensory Perception


The Myth<br />

The Details<br />

<strong>Helmet</strong>s cause an increase in accident rates by<br />

reducing hearing and/or peripheral vision.<br />

The Reality<br />

<strong>Helmet</strong> use does not significantly reduce<br />

peripheral vision nor diminish hearing.<br />

(Annals of Accident Prevention)

Myth # 7<br />

<strong>Helmet</strong>s Don’t Protect Against Other Injuries


The Myth<br />

The Details<br />

The extremities are most commonly injured in<br />

skiing and snowboarding. Head injuries make up<br />

relatively few of the proportion of injuries.<br />

The Reality<br />

Head injuries are the most expensive and most<br />

devastating injuries seen in skiing and<br />

snowboarding.<br />

Limiting the severity of a concomitant head injury<br />

reduces mortality in multi-system trauma.


The Science<br />

Of 361 Seriously injured skiers:<br />

Head injury mortality: 12%<br />

Multi-system trauma mortality: 6%<br />

Isolated thoracic or abdominal trauma mortality:<br />

0%<br />

Isolated extremity trauma mortality: 0%<br />

Myth # 6<br />

<strong>Helmet</strong>s Are Uncomfortable


The Myth<br />

The Details<br />

Skiers and snowboarders often don’t wear<br />

helmets because they are uncomfortable.<br />

The Reality<br />

New helmets are lighter, fit better, and are more<br />

comfortable.

Myth # 5<br />

<strong>Helmet</strong>s Only Work At Low Speeds


The Myth<br />

The Details<br />

There is no evidence that helmets protect against<br />

high-energy impacts.<br />

The Reality<br />

A helmet provides better protection than no<br />

helmet at any speed.


The Science<br />

The science behind ski helmet<br />

impact testing is commonly<br />

misunderstood.<br />

<strong>Helmet</strong> dropped against anvil to<br />

impart specific amount of force<br />

(not a specific speed).<br />

Ski and snowboard helmets are<br />

tested to about the same impact<br />

as motorcycle helmets.

Myth # 4<br />

<strong>Helmet</strong>s Don’t Prevent Traumatic Brain Injuries


The Myth<br />

The Details<br />

<strong>Helmet</strong>s may prevent minor concussions but don't<br />

necessarily reduce the severity of traumatic brain<br />

injuries.<br />

The Reality<br />

Any helmet which disperses impact energy<br />

reduces the potential for traumatic brain injuries.


The Science<br />

75% reduction in severe traumatic brain injuries via<br />

helmet use in cycling (Journal of Sports Medicine)<br />

33% reduction in hospitalizations and 56%<br />

reduction in fatalities from motorcycle accidents<br />

during period of helmet enforcement (Taiwan)

Myth # 3<br />

<strong>Helmet</strong>s Encourage Recklessness


The Myth<br />

The Details<br />

People feel safer wearing helmets, so they are<br />

willing to take greater risks.<br />

The Reality<br />

Risk-taking is encouraged by the nature of certain<br />

professional and extreme sports.<br />

Age and gender influence risk-taking behavior far<br />

more than helmet use.


The Science<br />

Young males are at significantly higher risk of head<br />

injury due to risk-taking behavior, not helmet use.<br />

(Journal of Trauma)<br />

Non-helmeted motorcycle riders exceed the speed<br />

limit more frequently than helmeted riders. (Annals<br />

of Emergency Medicine)

Myth # 2<br />

<strong>Helmet</strong>s Increase Cervical Injuries


The Myth<br />

The Details<br />

The weight of a helmet increases the chance<br />

that the wearer will suffer a neck injury.<br />

The Reality<br />

Cochrane Review found no well conducted<br />

studies relating cervical injury rates to helmet use.


The Science<br />

In a study of consecutive cases of skiers and<br />

snowboarders with spinal injuries<br />

(St. Anthony Central)<br />

Of patients with cervical injuries, none were<br />

wearing helmets<br />

Of patients wearing helmets, none suffered<br />

cervical injuries<br />

No cervical injuries in helmeted kids under 13


The Science<br />

Un-helmeted children are 2.24 times more likely<br />

than helmeted children to suffer head/neck/facial<br />

injuries. (Journal of Injury Prevention)<br />

No change in incidence of cervical injuries after<br />

implementation of mandatory helmet law in<br />

Taiwan.

Myth # 1<br />

<strong>Helmet</strong>s Are Only For Beginners


The Myth<br />

The Details<br />

Increased skill levels make helmets unnecessary<br />

because of a lower incidence of head injuries.<br />

The Reality<br />

Advanced-level skiers are more likely to suffer<br />

head injuries than beginners or intermediates.


The Science<br />

One study of injured skiers found that 26% were<br />

beginners, 29% intermediates, and 45%<br />

advanced.<br />

(Journal of Trauma)<br />

<strong>Helmet</strong> use is associated with expert ability,<br />

higher number of days skied per year, and higher<br />

education, all factors correlating with lower<br />

incidence of head injuries.<br />

(Journal of Trauma)
