The mechanisms that have been implicated to date for this phenomenon are venous posture due to prolonged sitting posture, pressure exerted on the large vein behind the knee, blood buildup due to reduced intake and increased fluid loss, abnormalities in the system, and blood coagulation created in the subarctic and
