Lightning damages the human body. It kills people directly close to trees or the ground. The kind of lightning that usually hits people is cloud to ground lightning. Lightning can affect all organs in the body. A lightning strike can give you cardiac arrest which is when your heart stops beating. Lightning can change the hearts rhythm but the heart usually resumes its normal heart rhythm. CPR can often revive these people.
Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating because there is relatively little blood flow in them to carry away excess heat.
