Yes, lightning can travel through plumbing and water, making showers during storms potentially dangerous.
Understanding Lightning and Its Pathways
Lightning is a powerful natural electrical discharge that can carry up to a billion volts of electricity. It typically strikes the tallest object in its path or follows the path of least resistance to the ground. While it’s well-known that being outdoors during a thunderstorm is risky, many don’t realize how lightning can affect indoor activities, especially those involving water and metal plumbing.
Water is an excellent conductor of electricity, especially when mixed with minerals found in household pipes. When lightning strikes a house or nearby area, the electrical current can travel through metal pipes and water inside them. This means that activities involving direct contact with plumbing—like taking a shower—can expose you to the risk of electric shock from lightning.
How Lightning Travels Indoors Through Plumbing
Lightning doesn’t have to directly hit a person to cause harm indoors. Here’s how it works: When lightning strikes your home or nearby power lines, the electrical charge seeks a path to the ground. Metal plumbing systems, often connected throughout a building and buried deep into the earth, provide such a pathway.
The water inside these pipes acts as a conduit for electricity. Even plastic pipes aren’t completely safe if they are connected to metal fixtures like faucets or showerheads. The current can jump through these metal components and into the water stream you’re touching.
This phenomenon explains why experts advise against using any plumbing-related fixtures during thunderstorms—not just showers but also sinks, bathtubs, and even washing machines.
The Role of Plumbing Materials
Older homes often have copper or galvanized steel pipes, both excellent conductors of electricity. Newer constructions might use PVC or other plastic piping which are poor conductors themselves but are still connected to metal fixtures.
Here’s how different materials influence risk:
- Copper Pipes: Highly conductive; pose significant risk during lightning strikes.
- Galvanized Steel Pipes: Also highly conductive; similar risk as copper.
- Plastic Pipes (PVC/PEX): Poor conductors but often connected to metal fixtures that can carry current.
Therefore, even if your home has plastic piping, touching metal faucets or showerheads during a storm remains dangerous.
Statistics on Lightning-Related Injuries in Homes
Lightning injuries are more commonly associated with outdoor strikes; however, indoor incidents do occur. According to data from the National Weather Service (NWS) and safety organizations:
| Activity During Lightning Strike | % of Indoor Injuries | Risk Level |
|---|---|---|
| Using Plumbing Fixtures (Showers/Sinks) | 30% | High |
| Using Electrical Appliances | 40% | Moderate-High |
| Other Indoor Activities (e.g., standing near windows) | 30% | Moderate |
These numbers highlight that nearly one-third of indoor lightning injuries involve plumbing-related activities. Showers top the list because they involve direct contact with running water and metal fixtures simultaneously.
The Science Behind Showering During Thunderstorms
Water conducts electricity due to dissolved ions such as calcium, magnesium, and sodium present in tap water. When lightning strikes nearby:
- The electrical charge enters your home’s wiring or plumbing system.
- The current travels through metal pipes filled with water.
- If you’re showering, your body becomes part of the conduction path.
- The electric shock can cause severe injury or even death.
Besides conduction through water and pipes, damp tiled surfaces and metal fixtures increase shock risks by providing additional conductive paths.
Why Is Showering Riskier Than Other Indoor Activities?
Showering involves continuous contact with running water and metal components like faucets and showerheads—both excellent conductors. Your skin is wet, reducing its resistance to electrical flow significantly.
In contrast:
- Sitting on a couch or standing away from plumbing: Less direct conductive path exists.
- Using electronic devices: Risk depends on grounding and surge protection but generally lower than direct contact with water/plumbing.
This combination makes showering during thunderstorms particularly hazardous compared to other indoor actions.
Common Myths About Lightning Safety Indoors Debunked
Many believe that being indoors makes them completely safe from lightning strikes. That’s only partially true. Lightning can still enter buildings via wiring, phone lines, cable lines, or plumbing.
Myth 1: You’re 100% safe indoors during thunderstorms.
Fact: Electrical surges from lightning can travel indoors through wires and pipes causing shocks or fires.
Myth 2: Avoiding windows alone keeps you safe.
Fact: While staying away from windows reduces risk from shattered glass or side flashes, it doesn’t protect against conduction through plumbing or wiring.
Myth 3: You can safely use water indoors since it’s not outside.
Fact: Water inside pipes conducts electricity just as well as outside; this makes showers risky if lightning hits nearby.
Safety Precautions To Avoid Lightning Injuries Indoors
The best way to reduce risk is simple: avoid using plumbing-related fixtures during thunderstorms. Here are clear safety tips:
- Avoid showers/baths: Wait at least 30 minutes after thunder stops before using bathroom plumbing.
- Avoid washing dishes: Don’t use sinks while storms are active.
- Avoid using wired electronics: Unplug devices when possible; avoid corded phones during storms.
- Avoid contact with concrete floors/walls: These may contain conductive materials linked to grounding rods.
- If caught mid-shower: Exit carefully without touching metal parts directly; dry off quickly once safe.
These steps drastically reduce chances of injury caused by indirect lightning currents traveling indoors.
The Importance of Proper Grounding Systems in Homes
Modern homes are equipped with grounding systems designed to safely divert electrical surges into the earth. Proper grounding reduces damage caused by lightning strikes but does not eliminate all risks associated with using water during storms.
Homes lacking adequate grounding face higher risks because stray currents may flow unpredictably through household wiring and plumbing.
Having surge protectors installed on main electrical panels adds another layer of defense against power surges caused by lightning but doesn’t protect against conduction through water pipes directly contacting occupants.
The Physics Behind Why Water Conducts Electricity So Well During Storms
Pure distilled water is actually a poor conductor due to lack of free ions. However, tap water contains dissolved minerals making it an excellent conductor for electricity generated by lightning strikes.
Lightning currents often exceed tens of thousands of amperes—far beyond what typical household circuits handle—meaning any conductive path becomes extremely dangerous when carrying such high voltage pulses.
The human body has resistance ranging roughly from 1,000 ohms (wet skin) up to 100,000 ohms (dry skin). Wet skin dramatically lowers resistance allowing lethal currents to pass more easily when combined with conductive surfaces like wet tiles and running water in showers.
A Closer Look at Current Flow During Lightning Strikes Indoors
When lightning hits near your home:
- The surge enters via power lines or directly into grounded structures like plumbing.
- The current flows along metal pipes filled with ion-rich water toward grounding rods outside your home.
- If you’re touching running water connected to these pipes (like in a shower), part of this current passes through your body seeking ground.
This flow causes electric shock symptoms ranging from muscle contractions and burns up to cardiac arrest depending on intensity and duration.
The Real Dangers: Injury Types From Showering During Storms
Electric shocks caused by lightning traveling through shower plumbing can lead to various injuries:
- Burns: Contact points where current enters/exits skin may suffer severe burns internally and externally.
- Cardiac Arrest: Electric current disrupts heart rhythm leading potentially fatal arrhythmias like ventricular fibrillation.
- Nerve Damage: High voltage shocks damage nerves causing paralysis or chronic pain syndromes later on.
- Tetany/Muscle Contractions: Sudden involuntary muscle spasms may cause secondary injuries like falls in bathroom settings.
Survivors often require extensive medical treatment including cardiac monitoring, burn care, physical therapy for nerve/muscle recovery.
