Lightning can be exciting to watch, but it's a dangerous weather phenomenon—even when you're indoors. According to the Centers for Disease Control and Prevention, about 1 out of 3 lightning injuries occurs indoors.
To reduce your risk of being hit by lightning when you're inside, avoid these things:
Electronics. Lightning can travel through electrical systems, as well as radio and television reception systems. So don't use computers, laptops, washers, dryers, stoves or anything plugged into an electrical outlet.
Corded phones. It's OK to use cordless or cell phones.
Water. Lightning can travel through plumbing. So no bathing, showering or doing dishes during a thunderstorm.
Windows, doors, porches and concrete. Lightning can travel through metal wires and bars in concrete walls and flooring. Do not lie on or lean against concrete floors or walls during a thunderstorm.
