There are few things as comforting as a hot water bottle on a cold night, yet it is worth remembering that they can deteriorate over time.
Like many everyday items, hot water bottles have a shelf life. When used beyond their safe period or filled incorrectly, they can crack or burst, causing serious burns.
Understanding when to replace a hot water bottle, and knowing how to use it safely, is vital for ensuring that it remains a source of comfort rather than a potential hazard.
Do’s and don’ts for hot water bottle safety
Check the manufacturing date
Look for the date stamp near the neck of the bottle. If it is more than two years old, it should be replaced, as the rubber degrades over time.
Do not use if it shows signs of wear
Check the surface for any cracks, thinning, or stiffness. Even minor imperfections can cause a hot water bottle to rupture.
Use hot, not boiling, water
Always use tap water, approximately 60 °C, allowing boiled water to cool before pouring it in. Boiling water can damage the rubber.
Do not overfill
Fill the bottle only halfway, expel any excess air, and securely tighten the stopper. This allows room for the water to move and reduces the risk of splitting.
Always use a cover
Never place a hot water bottle directly on the skin. Always use a cover or wrap it in a soft blanket or towel to protect against burns.
Do not use for babies or young children
Their delicate skin is highly susceptible to burns, and they may not be able to alert an adult if the bottle becomes too hot or leaks.
Store properly
Empty the bottle after use and leave it to air dry. Store it in a cool, dark place to slow down the natural degradation of the material.
Over time, the rubber in hot water bottles can crack and fail, especially when exposed to hot water and sunlight. Boiling water can exacerbate this process, making rupture more likely and increasing the risk of serious burns or scalding.
