Science
We protect sports by providing a state-of-the-art concussion treatment.
Since its creation, PolarCap® has undergone rigorous clinical evaluation to assess its effectiveness in concussion treatment.
Confirmed by research and ongoing studies, PolarCap® has been proven to significantly improve recovery and reduce the risk of long-term effects following a concussion.
Intro
The Evidence Behind the treatment
PolarCap® has been shown to improve concussion recovery and reduce the risk of long-term concussion absence by up to 80%.
The graph compares athlete recovery data from a five-year clinical study published in the Journal of Neurotrauma. Each dot represents a player and the day they returned to play following a concussion. The study found that players using PolarCap® experienced improved recovery compared to those who were not treated with PolarCap®. Notably, PolarCap® reduced the risk of long-term concussion absence (3+ weeks) by up to 80%.
These results demonstrate that the PolarCap® group experienced both short-term recovery improvements and a significant reduction in long-term concussion absence. Read the full study below.

Journal of Neurotrauma: Swedish Hockey League (SHL) / Lund University clinical study
The scientific publication is an analysis of data from a 5-year study conducted in a collaboration between Lund University, the Swedish Hockey League (SHL), and HockeyAllsvenskan (HA). The results from the study show that treated players returned to play significantly sooner when using PolarCap®, as well as showing an immediate relief of symptoms. Most interestingly, the study also found that long-term absence (3 weeks or more) was greatly reduced among treated players, by almost 80 percent.

Penn State University
A clinical study from Penn State University utilizing functional MRI demonstrated that selective head and neck cooling treatment increases blood flow to the brain—counteracting the reduced blood flow commonly associated with concussions. The study highlights the potential of cold therapy in supporting brain recovery following head trauma.

Indications
The Impact of Concussions, Repetitive Head Trauma & Hyperthermia
PolarCap® is designed to enhance recovery from concussions (mTBI) and repetitive head impacts, providing a proactive solution to reduce their harmful effects. When an athlete experiences a concussion or repetitive sub-concussive impacts, the brain undergoes significant stress. If combined with hyperthermia (elevated brain temperature) which most athletes experience during sports, the damage can be even more severe. PolarCap® is designed to reduce these risks, enhancing recovery and supporting brain health.
