For individuals with known allergies or sensitivities to common metals like copper or magnesium, the use of water powered alarm clocks warrants careful consideration. While the amount of metal exposed to the skin or inhaled is generally minimal and contained within the clock’s housing, direct or prolonged contact with the internal components is unlikely during normal operation. However, in the event of a leak or if the clock is disassembled, potential exposure could occur.
If you have severe metal allergies, it would be prudent to thoroughly research the specific metals used in the construction of any water powered alarm clock you are considering. Manufacturers should ideally provide information about the materials used in their products. As a precautionary measure, or if you have significant concerns, it might be advisable to opt for a traditional battery-operated or mains-powered alarm clock to entirely avoid any potential risk of an allergic reaction.
