Anti-inflammatory: Laser therapy has an anti-edema (anti-swelling) effect. As a result, there is a reduction in swelling caused by bruising or inflammation.
Pain relief: It blocks pain transmitted by these cells to the brain which decreases nerve sensitivity. Also, due to the decreased inflammation, there is less edema and less pain. Another pain-blocking mechanism involves the production of high levels of pain killing chemicals such as endorphins and enkephalins from the brain and adrenal gland.
Growth of new and healthy tissues: The laser light increases the energy available to the cell so the cell can take on nutrients faster and get rid of waste products. As a result of exposure to laser light, damaged cells are repaired faster.
Increased blood flow to the injured site: Laser light will significantly increase the formation of new capillaries in damaged tissue which speeds up the healing process.
Increases cell activity: Laser therapy creates higher outputs of specific enzymes, greater oxygen and food particle loads for blood cells
