"Heat has been used by man for millennia, as much for the relief of everyday aches and pains as for thermal comfort under harsh climatic conditions. Therapeutic heat has been exploited by every society, in every known time, in a multiplicity of ways, and probably for every type of physical ailment.

Pain is caused by a temporary reduction in blood flow which activates our pain receptors. The elongated YuYu Bottle stands out because it takes advantage of the horizontal arrangement of sensory nerves supplying the human skin and deactivates the pain receptors at a molecular level.”

“YuYu is an innovative, highly adaptable and beneficial device for people with chronic pain. Rather than targeting a painful ‘spot’ (as do traditional hot water bottles), the YuYu can provide heat along its length and can be used along entire muscles.”

Lesley's Story

"My son was born with the rare condition Blackfan Diamond Anaemia and following a bone marrow transplant at the age of 11 his health has slowly deteriorated. My son is now 30 and spends most of his days in bed where he finds it most comfortable and has found heat treatment extremely beneficial for many years with the use of wheaties and an old hot water bottle he had as a child. I came across your hot water bottles online when I was actually looking for an extra bottle so that he could use two at a time because wheaties wear out, they are not washable and do not stay warm long enough to give any real benefit. I can say it’s been used virtually every day. The shape makes it perfect to either lay all the way down his spine or between his legs to give relief from his hips to his ankles and it’s excellent at maintaining the heat for quite a long period of time."

Natalie Archer's Story

Endometriosis is a very painful condition that occurs when tissue similar to the lining of the uterus is found in other parts of the body, usually the pelvic area. The condition can cause pain during “that time of the month” or even chronic pain, along with food intolerances, IBS symptoms, nausea and fatigue. Some days are worse than others. I have a great medical team in NYC who support me. But I always reach for my hot water bottle and a cup of tea on the bad days. I deeply believe that women deserve to live a happy and pain free life.


Pregnancy Benefits

It is proven that hot water bottles can halt pain, but are they safe to use whilst pregnant?


“Heat during pregnancy is only an issue if your core temperature rises significantly,” says Anne. “This wouldn’t happen with a hot water bottle. It's more likely if you were unwell with a high temperature or if you soaked in an extremely hot bath.” – Midwife Anne Richley (

A YuYu bottle is a great way to encourage your muscles to relax, soothing any pains, aches and cramps that are common during pregnancy. British Standard certificated, the YuYu has been vigorously tested for the safety of our customers.

“You’d be amazed at how much protection you baby has inside your tummy, and there are several ‘layers’ between the hot water bottle and baby, so they won’t be affected,” says Anne.
