Abstract Background: Concussions are a serious injury in ice hockey that has received a lot of attention in the media because players have had long-term symptoms and in some cases been forced to end their careers prematurely. Purpose of the study was to, based on the latest research, try to obtain a holistic view regarding the concussion problem and preventive measures in ice hockey. Method: The study was conducted as a narrative literature review where the selection of articles was carried out unsystematically. Results: Concussions account for 18% of all injuries in ice hockey and during an ice hockey career there is a 22% risk of having at least one concussion. Repeatable concussions can lead to long-term effects such as impaired physical and mental health and impaired cognitive ability over time. Using the right equipment and expanding player training has been suggested as important preventative measures. Conclusion: Concussions are a major problem in ice hockey and can have long-term negative effects on health. There seems to be a need for more comprehensive education which should be implemented from an early age.
