What makes lightning so dangerous?
Multiple reasons. The human body is made of of 98% water which is highly conductive. This is dangerous because the human heart and nervous system run on electrical impulses. When hit, the electrical signal travels through the body to the ground and can pass through the heart which can cause cardiac arrest. Also, the high voltage of lightning can create a large amount of heat, causing severe burns. This can be amplified if the person is wearing jewellery. The lightning can make the metal so hot that it melts on the skin.
