Hot-water bottles are very popular in many households. They help with many different types of pain, such as stomachaches, back pain, or menstrual cramps. However, using a hot-water bottle is not as easy as many people think. For example, making mistakes when filling the bottle can lead to scalds or burns. In addition, the amount of water and its temperature are crucial for using the heat source correctly. A hot-water bottle should also be stored in a specific way.
Filling a hot-water bottle correctly sounds very easy at first - however, the following article explains what you should bear in mind to minimize any risk of injury.

In these step-by-step instructions, we explain how to fill a hot-water bottle safely and correctly. 1.Choosing the right hot-water bottleHot-water bottles come in many different designs, but their basic principle is quite similar. They usually consist of a thickly lined, flat water bottle, often made of rubber, with a type of padding or cover on the outside. Some bottles have a thicker cover made of another material, such as PVC or heat-resistant plastic. This allows you to find the hot-water bottle that works best for you. The quality of the hot-water bottle must be good so that it does not burst or become porous.
2.Emptying the old waterUnscrew the stopper and pour the old water out of the bottle. If you leave the old water in the bottle, your hot-water bottle may become cold again more quickly. For hygiene reasons, it is also important to change the water regularly and wash out the bottle.
3.Heating the waterIf you want to fill your hot-water bottle with hot tap water, it is often not hot enough. Instead, you can boil water in a kettle. However, you should then let the water cool for a few minutes, as it is still too hot for the hot-water bottle. If the water is too hot, it can burn your skin even though it is inside the hot-water bottle. A suitable water temperature is around 60 degrees Celsius; for children, it is 40 degrees Celsius.
4.Filling the hot-water bottleWhen filling the hot-water bottle with water, be careful not to spill any. This could cause scalds. Make sure to hold the bottle by the neck. If you hold it by the body, it may lose stability and water may flow out of the top. You should also fill the hot-water bottle only two-thirds full, as otherwise the bottle could burst or hot water could run over your hands while you are filling it.
5.Squeezing the air out of the hot-water bottleAfter filling the hot-water bottle, you can carefully squeeze the remaining air out of it. Press until you see the water rise to the top. Then screw the stopper back onto the hot-water bottle and carefully check whether it is watertight.
Tips for filling a hot-water bottle correctly
Check the hot-water bottle for damage
Before using the hot-water bottle, you should check it for possible damage to prevent the bottle from leaking and protect yourself from scalds. Look for cracks or porous areas.
Do not use boiling water
You should avoid boiling water at all costs. Even if the hot-water bottle is watertight, prolonged contact with the skin can cause redness or burns. The heat also creates water vapor, which could cause the bottle to burst in the worst case.
Store the hot-water bottle empty
The hot-water bottle should be emptied before it is stored. If water remains in the bottle, the material may be subjected to excessive strain. The stopper should also not be screwed on completely, as otherwise the inside of the bottle cannot dry and additional moisture develops.
Tip: A hot-water bottle is a wonderful aid when you want to do something good for yourself after a strenuous day. It usually retains its temperature for several hours, but adding a few spoonfuls of salt to the hot water keeps it warm for even longer.
