Cold is related to human development. If the osmotic pressure of blood increases, the water in muscle and skin cells will flow back into the blood, and the oxygen that cannot flow normally will retreat to the lungs (the lungs are like the roots of plants, absorbing oxygen and water), causing the lungs to expand, further stimulating, nose congestion, stimulating sensitive nerves in the nose and sneezing. If the blood osmotic pressure changes badly at this time, it will cause cold symptoms such as runny nose (pouring water) and cough (pouring gas). Drinking more water at the beginning of a cold may lead to decreased immunity.
