You’re right to consider these concerns, especially since you’re experiencing stomach issues which might be connected. In the Siddha-Ayurvedic tradition, copper is believed to balance the tridoshas—vata, pitta, and kapha—in the body, clear ama (toxins), and boost agni (digestive fire). However, using copper vessels safely involves specific practices.
Yes, you should avoid putting hot water in a copper bottle. When copper is exposed to heat, its tendency to leach increases, potentially leading to copper toxicity if consumed excessively. Hot water and, even more critically, acidic liquids can react with copper. This could contribute to gastrointestinal distress or irritation.
It’s advisable to use your copper bottle for room temperature or cold water instead. Allow the water to sit in the bottle for around 6 to 8 hours—overnight is ideal—as this maximizes the health benefits, like improving digestion and detoxifying the system. Ensure you’re not storing liquids in it that are acidic in nature or too warm.
Given you’ve had a stomach issue, watch if symptoms persist, you should consult a healthcare provider to rule out any other causes or potential heavy metal exposure. Also, ensure you clean your copper bottle regularly with a gentle cleanser like lemon juice with salt to maintain its safety and efficacy.
Siddha-Ayurveda speaks highly of copper’s benefits. However, respecting its usage limits ensures you’re harnessing its positives without the downside of toxicity. If you’re still keen on using it for tea, consider a different vessel for heating and then transferring to another cup for drinking. This way, you can incorporate the benefits into your daily routine safely.
