    WHAT IS HEAT THERAPY?


    Heat therapy is also known as thermotherapy in medical language. In this therapy, heat-providing devices such as hot cloths, hot water bottles, heating pads, ultrasound, hydrocooler packs and whirlpool baths are used. It can help in reducing pain anywhere in the body. It is especially considered beneficial in rheumatoid arthritis, muscle spasms, reducing the pain of injury and repairing damaged tissues.

    Heat therapy (thermotherapy) can also be beneficial in many other problems. These include reducing joint stiffness and pain, as well as swelling problems, edema and increased blood flow. Heat therapy helps improve blood flow to the affected area, which can work relieve pain.

    TYPES OF HEAT THERAPY:


    There are mainly two types of heat therapy, moist heat and dry heat. Both of these are explained in detail below.

    (ii) DRY HEAT:

    It is also known as conducted heat therapy. It is done with the help of devices or sources of heat that are easy to use on specific parts of the body. These sources and equipment may include hot packs, hot gels, wraps, heating pads, infrared saunas and massage chairs.

    BENEFITS OF HEAT THERAPY:


    The benefits of thermotherapy (heat therapy) for health are many. They include:

    1. IN MUSCLE PAIN:

    According to a study, heat therapy may be beneficial in reducing pain. At the same time, an another research has shown that the use of heat therapy can improve blood flow in the body.

    WHAT IS COLD THERAPY?


    Cold therapy is also known as cryotherapy. In this technique, the affected part of the body is exposed to a very cold temperature for a few minutes.

    BENEFITS OF COLD THERAPY:


    The benefits of cryotherapy (cold therapy) may include:

    1. BENEFICIAL IN MIGRAINE:

    The use of cold therapy can be effective in the problem of migraine headaches. Research has revealed that cold therapy has been used to treat migraine for about 150 years. In research, a mixture of salt and ice was wrapped around the patient’s head. It was found that ice somewhat reduced migraine pain by cooling the blood passing through the intracranial vessels.

    4. REDUCE ARTHRITIS PAIN:

    The use of cold therapy can also be beneficial in inflammatory problems, such as arthritis. In a study conducted by scientists, it was found that through whole body cryotherapy, the pain in arthritis patients has been reduced to a great extent.

    In research, patients were seated in a cold chamber for an average of 2.5 minutes during treatment, which found that their joint pain condition temporarily improved after the treatment.

    5. EFFECTIVE ON THE NERVOUS SYSTEM:

    The use of cold therapy can be beneficial in reducing pain by numbing the nerves. Research has found that constricting blood vessels through ice therapy can relieve pain by temporarily numbing the nerves in the affected area.

    6. IN SKIN PROBLEMS:

    Along with many diseases, the positive effect of cold therapy has also been seen in skin related diseases. In fact, cryotherapy can improve antioxidant levels in the blood as well as reduce symptoms of dryness and itching caused by atopic dermatitis.

    HOW TO USE COLD THERAPY:


    Before using cold therapy, keep in mind that ice should not be applied directly to the skin, as it can cause damage to the skin and tissues.
