We treat everything from arthritis to pulled muscles to inflammation with ice packs or heating pads. Treating pain with hot and cold can be extremely effective for a number of different conditions and injuries, and easily affordable. The tricky part is knowing what situations calls for hot, and which calls for cold. Sometimes a single treatment will even include both.
As a general rule of thumb, use ice for acute injuries or pain, along with inflammation and swelling. Use heat for muscle pain or stiffness.
There are two different types of heat therapy: dry heat and moist heat. Both types of heat therapy should aim for “warm” as the ideal temperature instead of “hot.”
Professional heat therapy treatments can also be applied. Heat from an ultrasound, for example, can be used to help pain in tendonitis.
When applying heat therapy, you can choose to use local, regional, or whole body treatment. Local therapy is best for small areas of pain, like one stiff muscle. You could use small heated gel packs or a hot water bottle if you only want to treat an injury locally. Regional treatment is best for more widespread pain or stiffness, and could be achieved with a steamed towel, large heating pad, or heat wraps. Full body treatment would include options like saunas or a hot bath.
Heat therapy works by improving circulation and blood flow to a particular area due to increased temperature. Increasing the temperature of the afflicted area even slightly can soothe discomfort and increase muscle flexibility. Heat therapy can relax and soothe muscles and heal damaged tissue.
Heat therapy is often most beneficial when used for a good amount of time, unlike cold therapy, which needs to be limited.
Minor stiffness or tension can often be relieved with only 15 to 20 minutes of heat therapy.
Moderate to severe pain can benefit from longer sessions of heat therapy like warm bath, lasting between 30 minutes and two hours.
There are certain cases where heat therapy should not be used. If the area in question is either bruised or swollen (or both), it may be better to use cold therapy. Heat therapy also shouldn’t be applied to an area with an open wound.
People with certain pre-existing conditions should not use heat therapy due to higher risk of burns or complications due to heat application. These conditions include:
If you have either heart disease or hypertension, ask your doctor before using heat therapy. If you are pregnant, check with your doctor before using saunas or hot tubs.
There are a number of different ways to apply cold therapy to an affected area. Treatment options include:
Other types of cold therapy that are sometimes used include:
Cold therapy is also known as cryotherapy. It works by reducing blood flow to a particular area, which can significantly reduce inflammation and swelling that causes pain, especially around a joint or a tendon. It can temporarily reduce nerve activity, which can also relieve pain.
For home treatment, apply an ice pack wrapped in a towel or ice bath to the affected area. You should never apply a frozen item directly to the skin, as it can cause damage to the skin and tissues. Apply cold treatment as soon as possible after an injury.
Use cold therapy for short periods of time, several times a day. Ten to 15 minutes is fine, and no more than 20 minutes of cold therapy should be used at a time to prevent nerve, tissue, and skin damage. You can elevate the affected area for best results.
People with sensory disorders that prevent them from feeling certain sensations should not use cold therapy at home because they may not be able to feel if damage is being done. This includes diabetes, which can result in nerve damage and lessened sensitivity.
You should not use cold therapy on stiff muscles or joints.
Cold therapy should not be used if you have poor circulation.
Heat therapy should utilize “warm” temperatures instead of “hot” ones. If you use heat that’s too hot, you can burn the skin. If you have an infection and use heat therapy, there is a chance that the heat therapy could increase the risk of the infection spreading. Heat applied directly to a local area, like with heating packs, should not be used for more than 20 minutes at a time.
If you experience increased swelling, stop the treatment immediately.
If heat therapy hasn’t helped lessen any pain or discomfort after a week, or the pain increases within a few days, make an appointment to see your doctor.
If you’re not careful, cold therapy applied for too long or too directly can result in skin, tissue, or nerve damage.
If you have cardiovascular or heart disease, consult your doctor before using cold therapy.
If cold therapy hasn’t helped an injury or swelling within 48 hours, call your doctor.
Knowing when to use cold therapy and when to use heat therapy will significantly increase the effectiveness of the treatment. Some situations will require both. Arthritic patients, for example, may use heat for joint stiffness and cold for swelling and acute pain.
If either treatment makes the pain or discomfort worse, stop it immediately. If the treatment hasn’t helped much with regular use in a few days, you can make an appointment to see your doctor to discuss other treatment options.
It’s also important to call your doctor if you develop any bruising or skin changes over the course of treatment.
Anti-inflammatory is suitable for the relief from pain associated with non-serious arthritic conditions.
