Why is it dangerous to use a hair dryer while sitting in the bath tub?

Using a hair dryer while sitting in a bathtub is dangerous because water conducts electricity, increasing the risk of electric shock. If the hair dryer falls into the water or if the user is wet, it can create a direct path for electric current to flow, potentially leading to severe injury or death. Additionally, the combination of water and electrical devices can result in short circuits and fires. For safety, it's essential to keep electrical devices away from water.
