Why the chill

summary

In fact, we often know the saying "shudder in the cold", that is to say, how much we know about it. What causes chills? Let's take a look at why chills occur.

Why the chill

First, the basic center for regulating human body temperature is hypothalamus. There are heat sensitive and cold sensitive neurons in the preoptic area - the front of hypothalamus. They can sense the temperature changes of deep tissues of human body and participate in thermoregulation. At the same time, the regulatory temperature rise caused by the upward movement of the temperature setting point due to the effect of pyrogen causes fever.

Second, when the heat source makes the set point rise from 37 ° to 39 ° from the normal temperature, the cold sensitive neurons will be excited before the temperature reaches 39 ° and the body will strengthen heat production and inhibit heat dissipation, showing shivering reaction. Shivering mostly occurs before acute febrile diseases.

Third: the pathogenic agent of infectious diseases, acting on the body to cause fever, the patient's whole body chills, goose bumps and tremors, that is, muscle involuntary activity, which is called chills, referred to as shivering. Shivering is the first sign of high fever. During the period of shivering, the body temperature has already increased. In the early stage of fever, sometimes the patient only has chills all over the body without shivering, which is called chills.

matters needing attention

In case of cold war, we must not despise it. We must pay attention to it. Once there is cold war, we should take medication when necessary. We must not delay it to prevent the disease from aggravating. If the symptoms are not relieved, we need to go to the hospital for systematic treatment, so as not to delay the disease.
