During storms, people are often advised to stay away from windows and avoid standing under trees. However, another critical precaution is to avoid contact with water sources such as showering, washing dishes, or doing laundry.

The Dan.gers of Using Water During Thunderstorms

Experts warn that using water during a thunderstorm can pose significant risks.

The Centers for Disease Control and Prevention (CDC) in the U.S. strongly advises against any contact with water during thunderstorms, including showering, washing dishes, and using running water.

In an official statement, the CDC explains:

"Do not bathe, use a shower, wash dishes, or perform any activities involving water during a thunderstorm. Lightning can travel through a building's plumbing system. If the building has metal pipes, the risk is higher, but even plastic pipes can still conduct electricity. Avoiding water contact during a thunderstorm is the safest choice to reduce the risk of being struck by lightning."

Additionally, the CDC advises people to stay away from porches, balconies, windows, and doors when lightning is present. People should also avoid lying on concrete floors or leaning against concrete walls, as these structures may contain metal reinforcements that can conduct electricity.

Electrical Risks Associated with Lightning

Apart from water, electrical devices connected to power outlets should also be avoided during a thunderstorm. The use of corded telephones, computers, or plugged-in electronics increases the risk of electrical shock if lightning strikes the power lines. However, cell phones and wireless devices are safe as long as they are not plugged into a charger.

When lightning strikes a house, electricity tends to follow the path of least resistance to reach the ground. Metal pipes and water within plumbing systems serve as excellent conductors, making showers particularly dangerous during a thunderstorm.

A shower combines two major risk factors:

1. Water – which conducts electricity
2. Metal pipes – which enhance conductivity

This makes the shower one of the most dangerous places to be during a thunderstorm.

How Powerful is a Lightning Strike?

According to the U.S. National Weather Service (NWS), a single lightning strike can heat the surrounding air to 50,000°F (27,760°C) - five times hotter than the surface of the sun.

Immediately after the lightning flash, the surrounding air rapidly cools and contracts, generating the shockwave that we recognize as thunder.

The Deadly Impact of Lightning

Lightning can be fatal in various ways:

• Direct strike: A person hit directly by lightning is likely to die instantly. Survivors are extremely rare.
• Contact injury: If a person touches a car, metal structure, or another object struck by lightning, they can suffer burns, muscle injuries, or even brain damage.
• Ground current: Lightning can also travel through the ground and "jump" onto nearby people or objects, making even indirect exposure dangerous.
• Side flash: If lightning strikes a tall object (such as a tree or building), it can branch out and hit a nearby person.

How to Calculate Lightning Distance

The National Weather Service provides a simple formula to estimate how far lightning is from your location:

1.  Count the seconds between the lightning flash and the thunder sound.
2.  Divide this number by 5 to determine the distance in miles.
3.  For reference:
-  5 seconds = 1 mile (1.6 km)
-  15 seconds = 3 miles (4.8 km)
-  0 seconds = Lightning is extremely close, take immediate shelter!

Safety Measures During Thunderstorms

To minimize the risk of lightning-related injuries:

• Avoid showering, washing dishes, or using running water.
• Stay away from electrical devices connected to power outlets.
• Keep a safe distance from doors, windows, and balconies.
• Avoid lying or leaning on concrete surfaces.
• Seek shelter immediately if lightning is nearby.

By following these precautions, you can significantly reduce the risk of lightning-related injuries and stay
