00:00We have always been curious. Why do people swear that they will not be struck by lightning?
00:05In fact, the main cause of death in lightning storms is lightning itself.
00:10In thunderclouds, the top of the cloud is usually positively charged,
00:14and the bottom of the cloud is negatively charged.
00:17This will change the electric potential on the surrounding ground.
00:21When the ground accumulates a large amount of positive charge,
00:24once the negative charge in the cloud layer and the ground charge come into contact,
00:29it will trigger a huge lightning bolt.
00:32Its powerful current can easily strike people on the head.
00:35It can cause huge damage to the heart and nerves of the human body.
00:39Therefore, there is no connection between being struck by lightning and being cursed.
00:44Why is it easier to be struck while standing under a tree?
00:47What about a building?
00:48It turns out that the height and shape of trees make them easier targets for lightning strikes.
00:54The current passes through the tree trunk and causes damage to the people under the tree.
00:58Although high-rise buildings are also easily struck by lightning,
01:02cement is an insulator, so the people inside are relatively safe.
01:06But if you stand on a high-rise building, it is difficult to say.
01:10In addition, water is also conductive.
01:12When rowing in the water, the hull and rainwater are connected to form a conductive path,
01:17which will also increase the risk of being struck.
01:20Therefore, it is best not to go to the water on a lightning day.
01:23So what should you do if you encounter strong lightning in the open outdoors?
01:28Experts recommend placing your feet together and squatting down immediately
01:32to reduce the effective height of the human body as much as possible.
