Wheat bags can bring relief and comfort when they're used correctly. However, as with any product involving heat, they can pose a risk of fire and or injury if they aren't used correctly according to instructions.



The intended purpose of wheat bags is as relief for sports-related injuries, muscle strains and arthritis. The wheat bag should be used by placing the bag on the part of the body where pain is occurring.

  • Only use a wheat bag for direct application to the body and don’t cover it with blankets, pillows or warm clothing as overheated wheat bags can potentially ignite when heat is trapped.


  • When heating, don't leave the microwave unattended and make sure the wheat bag rotates freely in the microwave turntable.
  • Heat only for the specified time, and remember you shouldn’t reheat a bag that has been heated recently.
  • Saturating wheat bags with oils can create an added fire risk. If you choose to add oils to wheat bags, use them sparingly and only apply after heating and not before.
  • Wheat bags need to be hydrated so they don’t dry out. If you use the wheat bag infrequently, it may absorb enough moisture from the air. Otherwise, industry advice recommends applying moisture directly to the surface of the bag by lightly sprinkling or using a water spray bottle.


  • Only store the wheat bag when it has cooled completely (this can take up to 2 hours). Leave it to cool in a safe place where a fire would not spread, e.g. the kitchen sink.
  • Don’t store in excessively hot places such as a car seat in the sun, spontaneous heating can occur and although rare, could potentially pose a risk of fire.
  • Discard the wheat bag if there is evidence of over-heating, e.g. discolouration or charring.
  • If you smell burning, your wheat bag should be thrown away: Wheat will dry out over time and start to emit a cooked or burnt smell. This is letting you know that it is time to replace your wheat bag. Carefully remove the bag from the heat source and place it on a non-combustible surface, such as a sink or kitchen bench. Let the wheat bag completely cool, then throw it away.
