While taking a bath during regular rain isn't inherently dangerous, you should avoid taking a bath or shower during a thunderstorm.
The danger comes from lightning strikes. Lightning can travel through plumbing. The Centers for Disease Control and Prevention (CDC) specifically advises against showering, bathing, washing dishes, or any activity involving running water during a thunderstorm.
Here's a breakdown of the risks:
- Lightning and Plumbing: Metal pipes can conduct electricity from a lightning strike. While grounding exists in many modern plumbing systems, it's not a guarantee against electrical shock.
- Water as a Conductor: Water itself is a conductor of electricity. If lightning strikes near your home, the electrical current could travel through the water in your pipes.
- Risk Mitigation: Waiting 30 minutes after the last thunder before bathing or showering significantly reduces the risk.
Therefore, avoid using plumbing during thunderstorms to stay safe. Wait until the storm has passed.
