Ice Your Head for Concussions
While the current level of knowledge about concussions and recovery from them far exceeds what it was even 5 years ago, there is still much to be learned. Research into treatments that can manage symptoms and promote recovery is rapidly expanding and this includes research into head and neck cooling as a mode of treatment. Researchers in New Zealand have recently demonstrated that head and neck cooling with the Cryohelmet after sustaining a sports related brain injury (i.e. a concussion) can reduce the number and severity of symptoms when used immediately after the injury. More work is needed to understand how and why this method of treatment is effective, but the results of this pilot study were clear and pronounced.
In any case of an impact to the head, it is always best to exercise caution and seek proper medical attention. It is important to note that the participants in the above mentioned study were assessed and treated by a trained medical professional. If you suspect that someone has sustained a concussion, you can find information about the common signs and symptoms on the CDC's website and again, visit your doctor or emergency care facility for proper care and recommendations on treatment.
