Sleeping in the wind will not cause stroke of cerebrovascular disease, but will cause the occurrence of peripheral facial palsy, facial neuritis, which is often referred to as hanging line wind. The symptoms of facial palsy are caused by blowing wind, some aseptic inflammation or viral attack, which leads to facial nerve damage, manifesting as crooked eyes and mouth, shallow nasolabial folds, loss of frontal lines, cheek puffing and leakage, and inability to show teeth. In the acute stage, dehydration, reduction of facial nerve edema, anti-viral, and facial nerve nourishment should be given when hanging wind occurs. In the later stage, acupuncture, cupping and bloodletting can be used to help the recovery of facial palsy. The main thing is to pay attention in the usual way to avoid the invasion of some deficiency evil and thieving wind.
