Does Lightning Travel Through Water and Cause Injuries?

Lightning Strike and Water Interaction

Lightning can strike water with incredible force, creating a shockwave that can travel through the water at speeds of up to 1,000 feet per second. When lightning strikes a body of water, the electrical current can travel through the water as far as 100 feet or more, depending on the water’s depth and conductivity. This means that people in boats or swimming in the water can be at risk of being struck by lightning that has traveled through the water.

Injuries Associated with Lightning Strikes in Water

When a person is struck by lightning in water, they may experience severe burns, cardiac arrest, or neurological damage. Burns from lightning strikes can be particularly severe, as the electrical current can cause deep tissue damage and charring. Cardiac arrest can occur due to the electrical shock disrupting the heart’s normal functioning. Neurological damage may also occur, including numbness, tingling, or even paralysis.

First Aid and Safety Considerations

In the event of a lightning strike in water, it’s essential to provide immediate first aid and call for emergency medical help. If the person is unresponsive, not breathing, or not breathing normally, begin CPR (30 chest compressions to 2 breaths). If the person has burns, cool them with cool water for up to 10 minutes. If you’re in a boat, try to get as far away from the strike area as possible to avoid further injury. Always prioritize storm safety and seek shelter in a sturdy building or a hard-topped vehicle during a thunderstorm.
