The use of helmets by skiers and snowboarders decreases the risk and severity of head injuries and saves lives, new Johns Hopkins-led research suggests. The findings debunk long-held beliefs by some that the use of helmets gives athletes a false sense of security and promotes dangerous behavior that might increase injuries.
"There really is a great case to be made for wearing helmets," says Adil H. Haider, M.D., M.P.H., an associate professor of surgery at the Johns Hopkins University School of Medicine and the leader of the study published in the November issue of the Journal of Trauma and Acute Care Surgery. "By increasing awareness and giving people scientific proof, we hope behavior changes will follow."
Statistics show that roughly 10 million Americans ski or snowboard each year in the United States, with approximately 600,000 injuries reported annually. Up to 20 percent of those are head injuries, which mostly occur when skiers or snowboarders hit inanimate objects such as trees or the ground. Twenty-two percent of those head injuries are severe enough to cause loss of consciousness or concussion or even worse injuries. Often the injured were not wearing helmets, Haider and his team found.
Haider notes that traumatic head injuries among winter sports enthusiasts lead to hospitalization, death or long-term disability, and contribute to increased health care spending. Head injuries are the chief cause of death among skiers and snowboarders. For the study, Haider and his colleagues on the Injury Control and Violence Prevention Committee at the Eastern Association for the Surgery of Trauma searched the medical literature and reviewed in detail 16 published studies on injury in recreational skiers and snowboarders. Analysis showed that helmets are lifesavers and do not increase the risk of injury. As a result of this study, the Eastern Association for the Surgery of Trauma now recommends all skiers and snowboarders wear helmets.
There are no laws in the United States mandating the use of helmets among recreational skiers and snowboarders. In Austria, children are legally required to wear helmets, and across Europe there are efforts to pass similar legislation. Data from the 2009 to 2010 National Demographic Study done by the National Ski Areas Association, encompassing more than 130,000 interviews from across the United States, showed that ski helmet use is on the rise. Overall, some 57 percent of skiers and snowboarders wore helmets during the 2009-2010 ski season, compared with 25 percent during the 2002-2003 ski season. Haider and his family are avid skiers and all wear helmets on the slopes.
Haider says some skiers have long argued that wearing a helmet on the slopes lowers visibility, hampers the ability to hear what is going on around them and encourages risky behavior, because they feel invincible. Some skiers have also suggested that wearing a helmet increases the torque and whiplash felt when a skier does go down, making neck and cervical spine injury more likely.
"These are all just excuses," Haider says. "Our research shows none of those theories hold water."
The high-profile death in 2009 of actress Natasha Richardson after an injury sustained on a Canadian ski slope brought attention to the issue of helmet use. She was not wearing one. Haider, director of Johns Hopkins' Center for Surgical Trials and Outcomes Research, says Richardson hit her head when she fell backward at a low speed while on a beginner's "bunny" slope, and wearing a helmet likely would have prevented lethal head injury.
The study was supported by the National Institutes of Health's National Institute of General Medical Sciences (K23GM093112-01) and the American College of Surgeons' C. James Carrico Fellowship for the Study of Trauma and Critical Care.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
