Drinking copper water in summer can cause copper toxicity and acidity because the water develops a "warm" nature. To avoid this, experts suggest limiting intake to 1–2 glasses daily on an empty stomach and storing it for only 8 hours at room temperature. When used correctly, this practice purifies water by killing bacteria, boosts immunity, and aids digestion. It also helps detoxify the body and skin, as long as you take a break every 15 days to prevent mineral buildup.
