National Lightning Safety Awareness week started in 2001 to bring awareness to lightning safety and dangers. Since 2001, lightning fatalities in the United States have decreased from approximately 55 deaths per year to about 20 or less. This is likely due to increased awareness, safety measures, and quick emergency response. While fatalities have decreased, hundreds of individuals are still struck by lightning each year. Keep yourself informed and keep you and your family and friends safe during thunderstorms.
This week, we’ll dive into the essentials of lightning, from its fundamental basics to the latest advancements in lightning science. We’ll cover crucial indoor and outdoor safety measures with a special focus on lightning during sporting activities, including indoor swimming. Additionally, we’ll explore the medical effects of both direct and indirect lightning strikes, and conclude by outlining practical steps you can take to safeguard your home or business from lightning’s destructive power.
