How to use a heat bag correctly

Heat bags

Our heat bags contain premium wheat and are meant to be used therapeutically for the relief of aches and pains and to assist in the healing of muscle tears, sprains and other musculoskeletal injuries.

Heat bags must be used correctly and precautions taken to avoid burns.


Heating times are only a guideline and should be adjusted to suit personal requirements. When using a heat bag for the first time test in 30 second increments to determine the relationship between your microwave and the heat retention being achieved.

If the heat is not strong enough increase the heating time but do not exceed 150% of the instructed time. Eg: suggested time = 2 minutes so you can safely heat to 150% of this = 3 minutes.

Place the Heat Bag into the microwave; ensuring it does not obstruct the turntable.

DO NOT place a container of water into the microwave.  

After heating, evenly distribute the heat within the bag by giving it a little shake. Test the Heat Bag on the forearm, tolerance to heat can vary especially in the elderly and young. Testing it on the hand only is not adequate as the skin on the hand is more resistant to higher temperature whereas skin in other parts of the body is less tolerant.

If your Heat Bag is sectioned gently shake the bag to ensure the heat is evenly distributed to avoid the seams splitting.

It is recommended that the heat Bag be completely cool before reheating. However if it has cooled and further heating is required it can be reheated for half the recommended time. If overheating occurs, a burning smell may be detected. Carefully place the heat Bag onto a non-combustible surface such as a kitchen sink. Allow to cool completely then discard. Heat Bags are not recommended as bed warmers. Old, dry and overheated heat Bags have the possibility of combustion when placed under blankets or bedding where heat cannot escape. heat Bags are not recommended for children under 3 years of age.


Place the heat Bag into a plastic bag, seal and leave permanently in the freezer until required. Remove from the plastic bag & apply.


Make sure the heat Bag is completely cool and moisture free before storing in a cool dry place. It is recommended that the heat Bag be heated once a month for maintenance.

We hope you enjoy. Remember a heat Bag is designed to warm a person not a bed.
