When feverish temperature rises period symptom? Let's talk about it

When feverish temperature rises period symptom?

Many patients feel cold or aversion to cold, and can appear "chicken skin" and shivering, pale skin and other phenomena. Pale skin is caused by the reduction of blood flow due to skin vasoconstriction. Due to the decrease of superficial blood, the decrease of skin temperature and the stimulation of cold receptors, when the information is transmitted to the central nervous system, it will feel cold, and when it is serious, it will appear chilly.

At the same time, the impulse from sympathetic nerve causes the contraction of erector pili muscle, so "chicken skin" appears. Shivering is the irregular periodic contraction of skeletal muscle, which is caused by the impulse from hypothalamus, which is transmitted to the motor endplate through the motor nerve through the reticular spinal tract and the red nucleus spinal tract of the lateral spinal cord system.

The decrease of skin temperature is also one of the causes of shivering. Therefore, this period can also be called the shivering period. This period is due to the temperature adjustment reaction aroused by the temperature adjustment point moving up and the central temperature lower than the adjustment point. Therefore, the characteristics of heat metabolism are the decrease of heat dissipation and the increase of heat production and production. The heat production is greater than heat dissipation, so the body temperature rises. Therefore, when the patient feels chilly or chilly, the central temperature has actually risen.

matters needing attention

Water is better than medicine, fever, sweating body, often feed warm water supplement is necessary. Infants under half a year old should continue to use breast-feeding. Breast milk is easy to digest, can ensure nutritional needs, can supplement water. Diet should be light, easy to digest as the principle, oil, salt should be less, a small number of meals, avoid eating spicy and stimulating food. But do not have to avoid, in order to prevent malnutrition, decreased resistance.
