Heat has a relaxing effect as muscle tone is lowered. In addition, the heat also leads to an increase in blood flow and temperature in the tissue, so that pain-producing substances can be transported away better, resulting in a pain-relieving effect. Moist heat is particularly effective as it penetrates deeper into the tissue and is stored for longer.
Cold leads to muscle tension as muscle tone is increased. Cold therapy also causes nerve stimulation and is therefore very important in the treatment of neurological diseases.
