Heat Treatment and Cold Treatment for Hands
Applying a heat treatment or cold treatment is a common method for treating hand and finger injuries, stiffness, swelling, and pain. When used for fingers, hands, and wrists, these treatments can be very helpful for:
- Recent injuries, such as bruises or fractures
- Old injuries that are painful
- Swelling
- Stiffness
- Irritation
- Recovery after surgery
Diagnosis and Treatment
Benefits of a Heat Treatment for Hands
Heat or warmth will help get stiff or sore hands moving by increasing the blood flow and speeding up the molecules in tissues. Heat is helpful for some stiff joints and muscles, and it can be useful prior to an activity. We often see an athlete warming up before a workout, and your hand therapist may use heat to help loosen up your hands before your session.
A warm shower or bath can help some sore, stiff joints, especially in the early morning. A warm compress, also called moist heat, or heating pad, also called dry heat, can also relieve stiffness. However, too much heat could cause injury such as fainting, swelling, or burns to skin and tissues. A good guideline, though not absolute, is that heat should not be used for more than 15 minutes at a time to prevent unwanted side effects. Heat should never be so hot that it is painful.
Benefits of a Cold Treatment for Hands
If pain, swelling, and irritation are present after an activity or surgery, a cold treatment can reduce these symptoms. Cold temperatures slow down the molecules in tissues and reduce blood flow.
The most common cold treatment is ice or something that has been made cold by placing it in the freezer, such as a gel pack or ice therapy machine. Similarly, a general but not absolute rule is to apply ice for 15 minutes and then allow a 15-minute rest before reapplying.
As with heat, too much cold can slow down healing and stiffen sore joints, so use this treatment with moderation and typically only in the period just after injury. Applying ice or anything extremely cold to bare skin can cause a frostbite injury. Always wrap the source of cold in some sort of fabric. If a bandage or splint is too thick and the cold is not getting through, apply the cold near the area on exposed skin. Stop using ice if you feel extreme pain or numbness due to the cold. Talk to your surgeon about whether and for how long they recommend ice after hand surgery or injury.
Special Heat and Cold Treatments for Hands
Some special and more advanced heat or cold treatments may be used under the supervision of a therapist or physician.
Some options include:
- Therapeutic ultrasound: A qualified trained therapist may use ultrasound to heat deeper tissues slowly to help motion. The ultrasound waves can move through the tissue and cause the molecules to speed up and release heat.
- Contrast bath: The patient soaks their hand or fingers and alternates between hot and cold exposure. This expands and contracts the tissue to help it heal by “pumping” out swelling and inflammation.
- Paraffin wax or warm wax: This can be used to apply moist heat via machines that are highly regulated for safe temperatures and use a wax mixture that avoids skin burns and holds warmth over the area for a period of time until it cools and hardens. This treatment is also used by health spas for hands and feet relaxation.
