Don't shower during a thunderstorm. Here's why

CNN
The trees begin to move, the sky begins to darken and then you hear the distant sound. You can tell that danger is approaching when you hear the distant sound of thunder. According to the National Weather Service, you're likely within 10 mile of it.
Do not ignore the sound of thunder. Lightning can cause injury or death in unexpected ways. This includes while you're taking a bath, washing dishes or washing in the shower.
It is best to avoid water in a storm, as lightning can travel along plumbing. The US Centers for Disease Control and Prevention advised that you should not bathe, shower, wash dishes or wash your hand during a thunderstorm.
The CDC said that the risk of lightning travelling through pipes is lower with plastic than metal. The CDC added that it's best to avoid contact with plumbing or running water when there's a storm.
It's not just the outside that's dangerous. The agency warned people to stay away from porches, balconies and windows, not to go near doors or windows, and not to 'lie down on concrete floors, leaning against concrete walls'.
The CDC also said that you should 'Avoid using anything connected to an outlet such as computers and other electronic equipment'. Stay away from corded telephones. Cell phones and cordless telephones are safe... as long as they are not connected via a charger to an outlet.
The surface of the Sun is hotter
National Weather Service: "A thunderclap occurs when lightning strikes and heats the air around it to as high as 50,000 degrees Fahrenheit - 5 times hotter that the surface of the Sun." The air rapidly cools down and contracts immediately after the flash. The sound waves we hear are the result of this rapid expansion and contraction.
Lightning can kill many different ways. The CDC stated that a direct strike was most likely to be fatal. However, injuries like blunt trauma, skin lesions, burns, and brain, muscle, and eye injuries may occur when touching a metal car or object that has been struck by lightning. Lightning can travel through the earth, bounce off of a person or an object, or even flow up from objects close to the ground.
The weather service said that you can calculate the distance you are from the lightning but you should do this in a safe area so as not to be struck.
The service stated that if you count the seconds between the flash and sound of thunder and divide them by five, then 5 seconds is equal to 1 mile and 15 seconds is equal to 3 miles. Zero seconds is very close.
According to the CDC, most deaths and injuries happen when people are outdoors, particularly during the summer months, in the evenings and afternoons. Around 180 people are injured each year by lightning. 10% of those struck by lightning will die. The highest risk is for those who work outdoors, particularly in the Southeast. The CDC said that Florida and Texas had the highest number of deaths caused by lightning.
Do not lie down on the ground if you're caught outside. Lightning can cause electric currents to run along the surface of the ground. These currents are deadly from more than 100 feet. The CDC warned that no place is safe outside.
Avoid being under or near tall trees, as this will increase the risk of you being struck by lightning. If you can't find a safe place to hide, get into a ball position. Put your feet together and squat down. Tuck your head in, then cover your ears. Remember, this should only be used as a last option. Seek safe shelter first.'
