Ice packs and heating pads are the way to go when in pain. Treating pain with hot and cold therapy can be very effective for several conditions or injuries and easily affordable as well. However, the tricky part can be deciding when to apply hot and when to apply cold. At times, the therapy can include both the types.
As a general rule of thumb, ice is used for acute injuries or pain with characteristics of swelling or inflammation and heat is used for easing muscle pain or stiffness. Ultimately, both the therapies work well for treating pain.
How does heat and cold therapy relieve pain?
Both the therapies stimulate the body’s healing response. Heat therapy dilates the blood vessels, promotes blood circulation and alleviates muscle spasms. Additionally, it also alters the sensation of pain. Heat therapy employs heating pads or heating lamps for direct application of heat and also moist heat like warm baths, heated wash cloths or heated pads.
On the other hand, cold therapy constricts the blood vessels, reduces swelling and numbs any deep pain. At first, applying ice may be uncomfortable, but it helps by soothing acute pain. Cold therapy employs ice packs, coolant sprays, ice bath and also cryo-stretching, which uses cold to reduce muscle spasms during stretching.
