Harm of flow through flow passage

North-south convection and direct flow in the bedroom are naturally the most comfortable way to enjoy the cool. However, experts warn that when people steam outdoors at high temperature in summer, their sweat will leak and their pores will open, especially when they are tired or asleep. At this time, their body temperature will drop and their blood will become weak. If the cross flow is blown for a long time without proper heat preservation, germs will often take advantage of it and cause diseases such as wind-heat cold and scapulohumeral periarthritis.

Therefore, when taking a lunch break or sleeping at night, you should avoid nudity. Even if you are tired, don't try to be happy. A person sleeps on an open-air balcony, corridor, under a tree, by the river or by the sea, otherwise there will be a danger of shoulder pain.
