Fever feels cold because the body produces too much heat and dissipates less heat. Fever is a variety of pathogens invade the human body, the body’s resistance to foreign pathogens to produce a response, the general fever and chills with each period of time.
1. Rising body temperature: at this time usually fever chills in the rising body temperature, mainly heat production, less heat dissipation, the body can produce heat through muscle twitching. At this time, the peripheral blood vessels of the limbs are in a state of contraction, and the skin can be cold, not sweaty and pale.
2. High-temperature persistence period: At this time, the body temperature has reached the period of persistent high fever, and the heat production and heat dissipation have gradually reached a new dynamic balance, and there can be accelerated respiration, flushing, sweating and other manifestations.
3. Decrease in body temperature: when the body temperature decreases, heat production decreases, heat dissipation increases, and the peripheral blood vessels of the patient’s limbs are in a state of expansion, which can accelerate blood circulation and dissipate the heat from the body, which is manifested as a large amount of sweating.
In addition, in addition to feeling cold, fever is often accompanied by headache, dizziness and other manifestations, you need to go to the nearest hospital in time for further treatment and processing.
