Furthermore, there appear to be only few upsides to avoiding cold water. Cold water does decrease your gastrointestinal temperature and may slightly increase blood pressure in some people, but it will not cause fats to solidify in your digestive tract ( 13, 14).

Hot water bottles provide thermal comfort with all the windows open. Illustration by Marie Verdeil. Unsurprisingly, there’s little – or actually no – academic research into the energy savings potential of hot water bottles. Instead, in recent years scientists have investigated more sophisticated personal heating devices such as electrically heated desks and seats, radiant heat bulbs, or battery-powered heat pillows. [5-7] These alternatives look needlessly complex in comparison to the hot water bottle. Water can be heated in many ways both high-tech and low-tech, and containers can be made from locally available materials.There are numerous benefits to adequate hydration, including optimal brain function, sustained energy levels, and body temperature and blood pressure regulation ( 1, 2, 3, 4). I have sustained burns from hot water bottles when sleeping with them when drunk! It’s amazing how much damage they can do. I tend not to do that nowadays, and I also prefer bottles with covers as they are more comfortable to use and stay hotter longer. I have a couple which have amazing covers and actually stay warm all night and well into the next day, which is great if you are in bed with a cold or something.

I own (and frequently use) a metal Japanese hot water bottles as well as a pair of rubber bottles. While both styles do an excellent job of keeping me and my bed warm, I prefer the Japanese one over the rubber version. Most people get enough fluid by simply drinking to satisfy their thirst. However, if you’re very active, work outdoors, or live in a hot climate, you may need to drink more. Lower calorie intake Additionally, heat pillows don’t wear as much as pvc/rubber bottles and there’s no waste associated with their use. They can be produced from scrap fabric and food waste (cherry stones) or other organic materials, limiting waste potential in the production chain. Instead of using water, one could fill it with paraffin to keep it warm for a guesstimate of 6-8 hours. Heat the paraffin to above melting ‘point’. For a hand-warmer, I use an extra-wide coffee mug dedicated to this purpose and the microwave, heating for 2 - 2 1/4 minutes (depending on how cold my apartment is); then top it with a small porcelain dish that fits it perfectly, then topping that dish with a single fuzzy earmuff.Japanese water therapy involves timing your meals and water intake, supposedly cleansing your gut and healing disease.

Reading your article about water bottles, a possible improvement occured to me. Instead of using water, one could use a phase change material (PCM) instead. These store thermal energy as the lattent heat of fusion of the phase change from liquid to solid. Examples of these are the sodium acetate hydrate used in hand warmers, paraffin (wax) or even water/ice for cooling needs. A lot of these materials have energy densities that are seriously competitive (or even exceed) the energy release by a water bottle that is cooling down. They however have one major advantage: since most of the energy is released during the phase change, these materials will release heat at a constant temperature (melting temperature). Water releases lots of energy at first (at less safe temperatures) but the rate decreases exponentially as the temperature decreases (it’s literally an exponential decay function). This means that PCMs could provide a significant improvement to water bottles, by releasing energy at a more consistent, safer and more useful temperature. Hot water bottles are a safe and sustainable alternative for terrace heaters in bars and restaurants. This makes hot water bottles a safe and sustainable alternative for terrace heaters in bars and restaurants. The investment is minimal: a collection of hot water bottles and a kettle – the water can be re-used over and over again. Alternatively, everyone could bring their own hot water bottle and fill it up on the terrace. The savings in terms energy are indeed immense, and comfort is indeed higher than heating the whole room when I just sit behind the desk.

Hot water bottles can be combined with a blanket, which further increases thermal comfort. If I put a blanket over the lower part of my body when seated at my desk, it traps the heat from the bottles and keeps them warm for longer. Another way to investigate the energy savings potential of the hot water bottle is to calculate how much energy it takes to prepare one and compare that to the energy use of a central heating system. Because rubber or PVC bottles can only be filled up to two-thirds for safe and comfortable use, I assume a somewhat larger model – 3 L – which can hold two litres of water in practice.Keep a room moist. Old timers often put a kettle of water on the coal stove and let it steam the room. A room that is moist holds heat better than a dry room. Though drinking more water may help with constipation and blood pressure, there is no evidence that Japanese water therapy can treat or cure type 2 diabetes or cancer. However, drinking more water may bring along some other health benefits. Summary Oil lamps help. I find that in a well insulated space, a single oil lamp provides light and quite a bit of heat. Eskimos know that a single candle will heat up an igloo very nicely. To safely use rubber or PVC hot water bottles at higher water temperatures, it’s important to replace them after a few years of use, and to store them properly. If you really want to use higher water temperatures, metal hot water bottles – inside a cover to prevent skin burns – are the safest option. Curved rectangular hot-water bottle, France, 1751-1810. Made of pewter, an alloy of tin and lead, this hot-water bottle is engraved with birds and plants and has a curved shape to fit close against the body. Source: Science Museum, London.
