Cold Therapy or Hot Therapy: Which One Works Best?

 In Hot and Cold Therapy

This issue of choosing between cold therapy and heat therapy had caused a great deal of confusion. This is unfortunate, as treating an injury with ice or heat is a cheap and efficient method to speed up healing and recovery. Although they are both beneficial, hot and cold treatments produce different outcomes during the process of recovery. This article gives you the general idea about these methods and their effectiveness.

Cold Therapy

Ice therapy should be used for acute trauma, such as a muscle strain, a ligament sprain, a soft tissue contusion, and whenever swelling is present. Some other situations, where a cold compress is beneficial are minor burns, fever, and headaches. Whenever an acute injury occurred, the RICE (Rest, Ice, Compression, Elevation) protocol is the best first-aid treatment.

Cold therapy has two major effects on an injury. First of all, it blocks the pain by slowing down nerve conduction. Secondly, the blood vessels narrow due to cold, which reduces the local flow of blood and consecutively decreases swelling and inflammation. Another beneficial effect of cold therapy is a reduction of metabolism by lowering oxygen demand and therefore limiting further injury. As soon as the pain and swelling are gone, you can begin light exercise and start the natural healing process. Do not apply cold therapy for more than 20 minutes, as this may lead to frostbite.

For home treatment you can apply a towel-wrapped ice pack to the affected area. Make sure to avoid direct skin contact with a frozen item. Other options include ice baths and reusable cold packs. You should ice an injury as soon as possible.

Heat therapy

Unlike cold therapy, heat application intensifies local flow of blood, which in its turn brings more oxygen and nutrients to the area. Increased uptake of oxygen and nutrients speeds up the metabolic rate and is necessary to heal and regrow the injured structures. Tissue extensibility is also improved, as tight muscles and joints are warmed up and their stretching ability improves.

When tight, stiff muscles receive heat therapy, the stretching ability of tissue increases, joint stiffness and spasm pain decrease. This allows for an expedited recovery as the range of motion for the injured area increases. Do not exceed 20 minutes of heat therapy per application. Taking the stress of muscles and trigger points not only helps chronic pain, but also soothes the mind and the nervous system, as chronic stress and anxiety can by significant sources of chronic pain.

You can chose either local or whole body treatment when applying heat therapy. For smaller areas, such as a stiff joint a hot water bottle or a heated gel pack or a steamed towel will work best. Take a hot bath or visit a sauna for a full body treatment.

Heat and Ice Combined

Hot and Cold therapy can be used together in order to first constrict the blood vessels and decrease swelling, and then to speed up healing by warming up the area and increasing the circulation and metabolic rate. This protocol can be used after about 7 days, if the traditional RICE treatment was unsuccessful.

When Not to Use Ice and Heat

Heating up a fresh injury is a bad idea. If you apply a heat pad to a freshly sprained ankle, it’s going to swell up and become more painful. Ice therapy and stiff muscles are also a bad combination. Muscle spasms and trigger points can be easily mistaken for inflammation, and icing them will be a wrong call, as this will only cause more pain.  Trigger point therapy combined with heat therapy may be the best choice here.
