What is crosstalk?

Drawing, also called draft, is an air flow phenomenon in meteorology.

Drawing usually occurs in building gaps, high wall gaps, rooms with opposite doors and windows, or similar passages. Due to the different atmospheric temperatures on both sides of the air circulation, the air pressure causes the air to flow rapidly.

And due to obstructions such as buildings, gaps, doors, windows, corridors, etc. provide circulation channels to allow the atmosphere to pass quickly. The wind direction is generally from the shady side to the sunny side, and the wind speed is determined by the temperature difference between the two sides. The greater the temperature difference, the greater the wind speed, mostly in spring and autumn.

Extended information;

The north-south convection in the room is naturally the most comfortable way to enjoy the cool air. However, experts remind that in the summer heat, people sweat and pores open, especially when people are tired or asleep. At this time, the body temperature drops and the qi and blood are weak. If you do not pay attention to proper insulation, you will let the draft blow for a long time. , evil spirits often take advantage of the deficiency and cause wind-heat cold, frozen shoulder and other diseases. ?

Therefore, you should avoid being naked during lunch break or when going to bed at night. No matter how tired you are, don't try to have a good time. Sleep alone on an open-air balcony, in a corridor of a building, under a big tree, by a river or by the sea. Otherwise, you risk shoulder pain. ?

After entering summer, people will feel unbearably hot due to high temperatures, high humidity, and difficulty in evaporating water in the body. Therefore, many people try their best to stay cool. In fact, being too greedy for cold food is not good and can easily lead to illness.
