Last time we thought about the low body temperature caused by the SN (Stress Nerve).
Today I would like to talk about the relationship between the Autonomic Nervous System (ANS) and the Immune System. In the immune system, the White Blood Cell (WBC) plays a very important roll. The WBC of a healthy person consists of about 60% of granulocyte, about 35% of lymphocyte and about 5% of macrophage. So far it sounds scientific and difficult, but if you are interested in the occurring mechanism of allergies, please listen to me for a while, enduring.

When SN (Stress Nerve) is working, the function of granulocyte is active and when PSN (Relax Nerve) is working, the function of lymphocyte is active. In other words, if you are in stressful situation, granulocyte increases and if you are in relaxing situation, lymphocyte increases. You would think, “It is good to increase lymphocyte.” The answer is “Yes” but if the ratio of lymphocyte becomes over 50%, your body temperature goes into the low body temperature area which is less than 36 degree C (96.8 degree F), and allergic diseases tend to happen in this condition. That is, if there are a lot of lymphocytes, your body is strong to remove bacteria and virus, but if it is too much, it reacts to healthy cells and causes allergic reaction such as inflammation of skin, sneezing, runny nose, asthma.

The cause of this condition is a life which has too little stress. These days children don’t play outside so they are lacking in exercise and they miss the chance to get sunshine (ultraviolet ray) which stimulates the sympathetic nerve (Stress Nerve). They live in too clean environment and miss the chance of bacterial infection which also stimulates the sympathetic nerve (Stress Nerve). This sounds strange, right? Bacterial infection should be a bad thing and should be avoided. But since our body become too clean, lymphocyte loses an enemy to attack and instead reacts to pollen, tic, etc. which should be harmless to our body. That is to say, excessive indulgence makes allergic diseases. This reminds you about anything?
