How Does Icing an Injury Help?

The video explains the use of cryotherapy, or ice application, for treating injuries like sprains and muscle pulls. It discusses the body's inflammatory response, which can overreact and cause excessive swelling, potentially cutting off oxygen to cells. Cryotherapy helps by reducing swelling and slowing cell metabolism, allowing for better oxygen use. However, prolonged ice application can lead to hypothermia, causing increased blood flow and potentially worsening the injury. The video advises limiting ice application to 10-20 minutes at a time. Ice also reduces pain by slowing neuron signal transmission, providing comfort during the healing process.
