So you don’t want something made of a cheap material that’s going to burst over you but there’s also a right way to fill a hot water bottle. Second, you don’t want to boil the kettle completely, turn it off a little before boiling so that the water is very hot but not scalding, so even if you spill you won’t seriously burn yourself. Safety is a very important part of hot water bottles because as the name suggests, the water’s very hot! I prefer something fleecy but you get some nice hot water bottles that have knitted covers, whatever your preference you just want it to be soft if you’re going to share a bed with it! Well, it’s going to be water right? For most yes, but you also get microwaveable bags that are filled with materials such as wheat and beads and these are equally as good as their water counterparts.

First, never fill it all the way up, you only ever want to fill it up half to three-quarters full. And you want to try and push the excess air out. This way you can’t burst it. They’re designed so that they don’t burst of course but it’s good to be safe.
