How to Use a Wheat Heat Pack Safely – Dos & Don’ts
The Basics: How Wheat Heat Packs Work
Wheat naturally retains and releases heat slowly, making it ideal for gentle, long-lasting warmth. When heated in the microwave, each grain absorbs moisture from the air inside the pack and releases it gradually as radiant heat. That’s why wheat packs feel so good: the warmth seeps deep into muscles, improves circulation, and signals your nervous system to relax.
✅ DO: Follow Microwave Guidelines Carefully
Every microwave is different, and overheating is the number-one cause of burnt smells or damage.
| Microwave Power | Recommended Heating Time |
|---|---|
| 600–700 W | 90 seconds |
| 800–1000 W | 60–75 seconds |
| 1100 W + | 45–60 seconds |
Pro tips
-
Place a cup of water beside your heat pack to keep the grains hydrated.
-
Shake halfway through heating for even warmth.
-
Always test temperature on the inside of your wrist first.
DON’T: Reheat Too Soon or Too Long
If the pack’s still warm and you reheat it, the inner grains can overheat — leading to scorching or combustion.
Wait until it’s completely cool (30–40 min) before reheating.
If it smells burnt or feels dry, retire it gracefully.
✅ DO: Keep It Hydrated
Over time, repeated heating can dry the grains.
Rehydrate every few months:
-
Lightly mist with water, or
-
Place a small bowl of water in the microwave when heating.
This prevents burning and keeps the scent fresh.
DON’T: Heat Multiple Packs Together
Heating two or more packs at once often causes uneven heating.
Always heat one at a time for safety and consistency.
✅ DO: Care for the Cover
If your wheat pack has a removable cover, wash only the cover.
Never wash the inner pack — the grains absorb water.
For fixed covers, spot-clean with a damp cloth and air-dry completely.
DON’T: Store in Damp or Sealed Places
Moisture breeds mould.
Store your wheat heat pack in a cool, dry place, never plastic.
For long-term storage, pop it in a sealed container in the freezer to deter pests.
