Hot therapy works by improving circulation and blood flow to a particular area due to increased temperature. Increasing the temperature of the troubled area even slightly can soothe discomfort and increase muscle flexibility. Hot therapy can relax and soothe muscles and heal damaged tissue.

Benefits of Hot Therapy 

Hot therapy is one of the most effective ways to relieve pain. It is recommended to treat pain, aches and to promote relaxation.

1. Relieves Pain

Hot therapy is a great way to relieve pain.

2. Decrease Muscle Spasm

By applying heat to a specific area that is having muscle spasms you can reduce the spasm quickly without having to take any medications.

3. Reduce Stiffness

Place the heat wherever your muscles are stiff to help reduce your stiffness. The heat, along with stretching helps to break up lactic acid in your muscles.

4. Increase Blood Flow to Area of Injury

Heat therapy causes the blood flow to go to the exact spot of the injury. This allows the injury to heal faster. In this type of heat therapy you would only heat the area where injured so the blood flows to that exact area.

5. Causes Muscle Tissue to Become More Flexible

The heat helps to relax the muscles. When applying heat to your tissues it increases your blood flow or circulation and causes your connective tissues to become more flexible.

6. Can Treat Many health Issues

Heat therapy is used to treat many health problems like arthritis, muscle strains, muscle spasms and menstrual pain.

7. Treat Chronic Injuries

Chronic injuries are most likely always treated with some kind of heat. These injuries are classified as chronic when they are persistent over an extended period of time.

How to use Wrap-On Ice for Hot Therapy


This pack is prepared for hot use by either heating in the microwave oven or hot water immersion.


Because microwaves vary in power, you need to carefully determine the correct exposure time for the pack to your microwave oven. Before you begin, flatten the pack and ensure the gel is evenly distributed. If the pack is stored at room temperature, set the microwave to HIGH and heat the pack for 40 seconds then allow it to stand for 50 seconds. If the pack is stored in the freezer, set the microwave to HIGH and heat the pack for 60 seconds then allow to stand for 75 seconds. If the pack is inadequately hot after the first heating, reheat in the microwave in 10 seconds increments, with equal standing time, until the desired temperature is reached. Record the total heating required to reach the appropriate temperature for future use.


Wrap-On Ice – 1 Gel Pack

Boil approximately 4 litres of water in an appropriate sized pot. Once the water has boiled remove it from the heat and immerse the pack in the water for approximately 10 minutes. Carefully remove the pack from the hot water using tongs, or other appropriate utensil to avoid scalding, and dry.

Wrap-On Ice mini

Boil approximately 2 litres of water in an appropriate sized pot. Once the water has boiled remove it from the heat and immerse the gel pack in the water for approximately 5 minutes. Carefully remove the gel pack from the hot water using tongs and dry. Insert gel pack into the Wrap-On Ice sleeve, contour to the body and secure with black compression strap.


Insert the ice pack into the WRAP-ON ICE sleeve. Contour the pack to the injury site and secure with the black compression strap. Application times of 20 – 30 minutes are recommended. Repeat as required.
