Lightning is harmful primarily because of the electric current that passes through the body during a strike. While burns from the heat generated when lightning moves across the skin can occur, the current itself poses the greatest risk.
Understanding the Dangers of Lightning
The danger of lightning stems from a combination of factors, the most significant being the electric current:
-
Electric Current: According to the reference, the most serious threat comes from the current flowing through the body. This current can disrupt the body's electrical signals. This can result in cardiac arrest, seizures, and respiratory failure.
-
Heat: While not the primary danger, the intense heat from a lightning strike can cause severe burns.
-
Trauma: Lightning strikes can also cause blunt force trauma if the person is thrown or experiences a muscle spasm leading to falls.
Factors Influencing Survival
Survival after a lightning strike is influenced by several things:
-
Amount of Current: The amount of electrical current passing through the body is a major factor in determining the severity of the injury.
-
Speed of Medical Attention: As stated in the reference, immediate medical attention is crucial for improving the chances of survival after a lightning strike. Prompt CPR and advanced life support can be life-saving.
Table: Key Dangers of Lightning
| Danger | Description |
|---|---|
| Electric Current | Disrupts the body's electrical signals, leading to cardiac arrest, seizures, and respiratory failure. This is of greatest concern. |
| Heat | Causes burns as lightning moves over the skin. While less dangerous than the current, burns can still be severe. |
| Trauma | Blunt force injuries can occur if the person is thrown or suffers muscle spasms leading to falls. |
