can we keep hot water in copper bottle - #24268
I am wondering if we can keep hot water in a copper bottle. Last week, I got this beautiful copper water bottle, and I've been hearing all these fantastic benefits about drinking water from copper. But I’m not sure about the whole hot water thing. I usually start my mornings with hot water, and since I got the bottle, I thought maybe I could just pour my morning brew into it. But then I heard that heating copper could be bad or maybe there are specific temperatures where it becomes dangerous? Are there any particular guidelines? Like, can we keep hot water in a copper bottle overnight? What if it's steaming hot when I pour it in – is that fine, or should it be cooled down a bit? My friend says that keeping hot water in a copper bottle is a great way to boost health, but I don’t want to take any unnecessary risks. I just want a bit of clarity! Also, are there any specific brands or qualities of copper bottles that are better than others for this kind of use? Guess I need to rethink my routine if this hot water thing doesn’t add up!

Doctors' responses
Using copper bottles for daily water consumption can be generally considered safe, but discerning whether you should use them specifically for hot water is indeed a valid concern. Typically, the benefits of drinking from copper bottles, such as potential antimicrobial effects, are obtained when water is stored in them at room temperature. The practice of Ayurveda has contributed to this belief, recommending storing water overnight and drinking it in the morning. However, regarding hot water, there’s a nuance worth noting. When copper is exposed to high temperatures or certain acids, it can leach into the water in higher amounts, which might surpass the safe threshold for daily copper intake. While copper is an essential trace element, overconsumption can lead to health issues such as gastrointestinal discomfort, detrimental effects on liver or kidney function, and in extreme cases even copper toxicity. Therefore, it’s generally advised not to store hot or boiling water in copper vessels. Over prolonged periods, this could lead to excessive copper exposure, potentially harmful. If you’re heating water, it would be wise to let it cool slightly before pouring it into a copper bottle to avoid these risks. Allowing it to reach a warm—rather than steaming—temperature significantly minimizes leaching. In that context, the material and quality of the bottle matter as well; unlined bottles’ interior could allow more copper dissolution under high temperatures compared to lacquered or lined ones. Therefore, ensure that if you do use a copper bottle, it is intended for such uses, which might be reflected in the manufacturer’s instructions or product guidance. Generally, it’s best to use a different material for hot beverages like stainless steel, which might be more suitable when it comes to maintaining various temperatures, including hot and cold. If considering this for your routine, seek alternatives that are guaranteed and tested for thermal stability. If there are still uncertainties or you’re looking for a health boost through copper, it’s better focus on using the bottle at room or slightly cool temperatures.
