There's nothing worse than being cold at night - shivering in bed is basically the antithesis of fun. But one amazing new product looks set to fix all that ...

​The Body Bottle promises to be a total game-changer.

Far superior to the typical hot water bottle, this little number is super long, meaning you can use it to warm up multiple parts of your body at the same time!

But thanks to its slim shape, it only requires a couple of pints of warm water to fill it up!

The rubber bottle also comes with a cozy fleece cover which feels soft and luxurious against your skin. The bottle has a bumpy design which helps keep the heat in for longer, plus it's biodegradable and therefore eco-friendly, too.

The product description also gives tips on how to get the most out of your bottle.

You shouldn't fill it directly with boiling water, always allowing a minute for it to cool a little first. You should never overfill, and make sure any excess air is squeezed out before you put in the stopper. And when you're not using your hot water bottle, it should be kept in a cool, dry place. Hang it upside down before storing to ensure any water inside dries off.

The hot water bottle is a huge hit.

It currently has a 4.4. out of 5-star rating, with many happy customers sharing their testimonies.

"Easily one of the best purchases made so far this year. I suffer from endometriosis which can be downright painful. Having tried some of the smaller options I find this one to be just about perfect. I can easily use it sitting on the couch or laying in bed, and it retains heat for a long period of time. If you have any sort of chronic pain or inflammation this is a good buy," wrote one satisfied customer.

​"I am so glad I decided to buy this. It's helped me with cramps and many other pain-related issues. And you can wrap it around your body which is a plus. It stays warm for a really long time. If you're dealing with muscle pain, period pain, soreness, etc. I would recommend you buy this!" another added.
