Why can't you shelter from the rain under the tree on rainy days?

Because standing under a big tree, when powerful lightning flows through the tree and spreads around, it will produce different voltages in different places, and the voltage difference between human feet will cause harm, which is usually called step voltage injury. If you have to hide under the tree to avoid the rain, you must keep a distance of 3 meters from the trunk.

Judging from the formation and occurrence process of lightning, lightning accidents often occur in open fields, roofs of buildings, tall trees, rivers, lakes, ponds and wet areas. When it thunders, you should immediately stop outdoor activities and look for lightning protection places as soon as possible. You can take refuge in low-lying, dry or leeward houses or caves. However, low-rise buildings without lightning protection facilities, such as shacks and sentry boxes, cannot enter.

When it thunders, if you are driving, don't "abandon the car" and stay in the car. The car shell is made of metal. Because of the shielding effect, even if lightning hits the car, it will not hurt people. The carriage is an ideal place to avoid lightning.
