Showering During a Storm: Why Physicists Warn Against It

5 August 2026 Poland Radar 0 Comments

Physicists warn that showering during a storm can pose real risks due to conductive plumbing and water. Read practical advice for expats.

Showering during a storm still carries measurable risk, scientists say, so postpone baths and showers until the worst passes. Consequently, experts recommend avoiding any contact with running water during intense thunderstorms.

Why water and pipes attract lightning

Physicists explain that lightning finds the fastest path to ground. Therefore, metal pipes and flowing water can form such a path. Moreover, a bolt that hits a house can spread current through conductive structures. Even if a building has a lightning rod, some current can still travel through the plumbing. In addition, many homes have metal fittings, joints, or earthing elements. Thus, a person in a bathtub or using a shower can become part of that path.

How common are indoor lightning incidents

Statistics show the risk is low but not zero. Consequently, researchers estimate direct lightning strikes to a person at about one in a million. However, experts note that about a third of lightning injuries happen indoors. In addition, meteorological services report annual incidents tied to household plumbing. Therefore, emergency responders recommend simple precautions. For example, delay water use for the storm’s peak. The cost of waiting is small. The potential harm can be severe.

showering during a storm: what the data and physics say

Researchers and medics stress that plumbing often helps current reach people. Moreover, flowing water itself conducts electricity. Even plastic pipes may still contain water that carries current. Therefore, modern homes with mostly plastic piping reduce risk but do not remove it. In practice, few buildings lack all metal connectors, taps, or grounded fixtures. Consequently, authorities advise treating the rule as universal. In other words, do not depend solely on a home’s age when deciding.

💡 GOOD TO KNOW: In Poland, many basic processes differ from what expats expect. For safety, follow local weather alerts. If you live in a shared building, ask your landlord about the plumbing material. Also, note key Polish institutions: ZUS is the social insurance office, NFZ is the public health fund, PESEL is the national ID number, and a mandat is a fine for minor offences. If you need emergency care after an incident, use your NFZ coverage or private insurance. Finally, keep a mobile phone charged and save local emergency numbers.

Practical advice matters. Therefore, during a thunderstorm avoid washing dishes, showering, bathing, or touching metal faucets. Moreover, unplug sensitive electronics if lightning strikes are nearby. However, do not panic. The odds remain low. Even so, the simple step of waiting 15 to 60 minutes greatly reduces the small risk.

For expats, local housing can influence exposure. Older Warsaw tenements may contain metal pipes. Newer flats often use plastic piping. Nevertheless, many apartments still have metal taps and connectors. Consequently, ask building managers about plumbing and grounding. Moreover, landlords must address safety hazards under Polish housing rules. If you receive a mandat (fine) for violation of certain safety codes, know how to appeal. In addition, keep copies of your documents like PESEL in a safe place.

Overall, the physics and data support caution. Therefore, treat the old warning as practical advice, not mere superstition. Waiting a short while can prevent a life-changing injury.
