Physical cooling is suitable for patients with high fever and good circulation. It is characterized by simple methods and few adverse reactions.

●Warm water bath

The temperature of the water should be slightly lower than the patient's skin temperature (i.e. 32℃-34℃). After the skin receives cold stimulation, it can make the capillaries contract and then dilate to achieve the cooling effect. When rubbing the bath can also be used to stimulate the passive dilation of blood vessels with massage techniques to promote heat dissipation. Note that when rubbing the bath force to be uniform, gently massage a few, but also can promote vascular expansion. Rub to the armpits, groin and other blood vessels in the rich place to stay a little longer to help dissipate heat. The limbs and back each rub bath 3-5 minutes.

●Alcohol bath

When using alcohol bath should pay attention to the concentration of alcohol, generally 30% -50% concentration is appropriate. Alcohol should not be too cold, the temperature of 32 ℃ - 35 ℃ is appropriate. Use gauze or towel dipped in alcohol and then wipe regularly. This usually starts with the patient's neck and rubs top-down along the outside of the upper arm to the back of the hand. Then rub along the inside of the upper arm through the armpit to the palm of the hand. After the upper limbs are wiped, the back is wiped from the neck downward, and the back is gently massaged and patted with the other hand while wiping the bath to promote blood circulation. Finally from the ilium began to wipe the lower limbs, the same method and wipe the upper limbs.

Expanded

Fever, also known as fever, refers to the direct effect of the pyrogen on the thermoregulatory center, dysfunction of the thermoregulatory center, or a variety of reasons for excessive heat production, heat dissipation is reduced, resulting in an increase in body temperature above the normal range of cases. The normal body temperature varies slightly from person to person and is affected by time, season, environment, menstruation and other factors.

Fever is generally considered to be present when the oral temperature is higher than 37.5 ℃, the axillary temperature is higher than 37 ℃, or the difference in temperature between one day and another is more than 1 ℃. Fever is the most common clinical symptom, is an important clinical manifestation in the process of disease progression, can be seen in a variety of infectious and non-infectious diseases. But sometimes elevated body temperature is not always caused by disease, some cases can have physiological temperature rise, such as strenuous exercise, pre-menstrual period and pregnancy, into the high temperature environment or hot water bath, etc. can make the body temperature is slightly higher than usual, these self-regulation can be restored to normal.
