Traditional hot water bottles are filled with boiling water, and closed with a plug. Microwavable hot water bottles, as opposed to regular ones, do not require boiling water and using stoppers. They are very safe and simple to use, and they heat up rapidly due to the inner thermal pack. In most cases, you just need to microwave a hot water bottle for 60 seconds, if you need warmth right away. They are not only excellent bed warmers, but they also offer multiple health benefits. The heat from hot water bottles increases blood circulation, providing pain relief for anyone suffering from chronic muscular aches or joint stiffness, neck and shoulder discomfort, or arthritis. Furthermore, heat stimulates the release of oxytocin and serotonin, the hormones of happiness, and brings instant stress relief. Hot water bottles are made of plant-based materials and water, which heats up when warmed in the microwave.  There are no water currents inside microwavable heat bags, so the transmission of warmth from the centre to the exterior takes more time than with regular hot water bottles, resulting in the heat pack being warmer for longer. Our microwavable hot water bottles are available in a variety of designs, including a long bottle variant, animal plush shape, different colours, and foot warmers/foot muffs to keep feet warm during the chilly winter season.
