How to Use a Hot Water Bag Safely + Tips

1. Fill with warm — not boiling — water (about 104-113°F / 40-45 °C). Let boil cool slightly before pouring.
2. Fill to 2/3 capacity to allow room for movement, then expel air before sealing tightly.
3. Always wrap the bag in a soft cover or cloth; never apply bare to skin for long.
4. Test on your hand first for 30 seconds to ensure temperature is safe.
5. Use foot positioning so the bottle touches the sole and arch for max contact.
6. Check for leaks before bed; discard and replace if any cracks or weaknesses appear annually.
7. For extended use, top up with warm (not scalding) water mid-night if needed.

Benefits of Sleeping with a Hot Water Bottle (or Large Hot Water Bag)

• Enhances sleep quality: lower core temperature drop triggers better sleep onset.
