Can Lightning Cause Long-Term Health Issues?

April 6, 2026

Quick Answer

LONG-TERM HEALTH ISSUES FROM LIGHTNING STRIKES ARE RARE BUT CAN OCCUR DUE TO NEUROLOGICAL DAMAGE, HEART ARRHYTHMIAS, AND RADIATION SYNDROME. THESE COMPLICATIONS MAY NOT BE IMMEDIATELY APPARENT BUT CAN DEVELOP WEEKS, MONTHS, OR EVEN YEARS AFTER THE INCIDENT.

Lightning Strike Injuries and Neurological Damage

Lightning strikes can cause a range of injuries, from minor burns to severe neurological damage. The extreme electrical current can disrupt normal brain function, leading to seizures, muscle weakness, and even paralysis. In some cases, lightning strike survivors may experience long-term neurological damage, including memory loss, cognitive impairment, and mood disorders.

First Aid and CPR for Lightning Strike Victims

When responding to a lightning strike, it’s essential to prioritize first aid and CPR. The American Red Cross recommends the following steps:

  • Call 911 or your local emergency number immediately
  • Check the victim’s airway, breathing, and circulation (ABCs)
  • Provide CPR if the victim is unresponsive and not breathing
  • Use a blanket or jacket to keep the victim warm, but avoid covering their head or neck

Storm Safety and Prevention

Preventing lightning strikes is the best course of action. When a thunderstorm approaches, take the following precautions:

  • Monitor weather forecasts and warnings
  • Avoid being in open areas or near tall objects
  • Seek shelter in a sturdy building or a hard-topped vehicle
  • Avoid using conductive objects such as golf clubs or metal fences when outdoors

When in a storm, it’s essential to prioritize safety over trying to rescue someone who has been struck by lightning. If you’re in a group and someone is struck, focus on providing basic first aid and calling for emergency services.
