Cold exposure stimulates vasoconstriction and subsequent vasodilation, leading to enhanced circulation. Think of this like a pump that helps return venous blood back to the heart and circulate lymphatic fluid throughout the body. The alternating constriction and dilation of blood vessels improves blood flow, nutrient delivery, and waste product removal. Additionally, this "pumping" effect on the lymphatic system can facilitate the removal of waste products and toxins, further aiding in reducing inflammation and promoting overall detoxification, which can get backed up due to a lack of muscle movement or an inefficient lymphatic system.
