Introduction

Fever reduction refers to antipyresis. After fever subsides, if the body feels extremely cold, it is important to promptly add clothing, replenish fluids, and take medication. During the process of fever reduction, excessive sweating without timely fluid replacement can lead to dehydration, thereby reducing effective circulating blood volume and causing chills throughout the body. Drinking plenty of water helps provide adequate hydration and maintain normal fluid balance in the body.

Generally speaking, fever reduction refers to antipyresis. Feeling cold all over the body after fever reduction is usually caused by a rapid drop in body temperature. This can be alleviated by adding clothing, replenishing fluids, taking medication, and other methods. The details are as follows:

1. Add clothing

If cold hands and feet are caused by a cold environment, it is recommended that patients add appropriate clothing. Taking a warm water bath may also help promote blood circulation and increase body temperature.

2. Replenish fluids

During the process of fever reduction, excessive sweating without timely fluid replacement can lead to dehydration, resulting in reduced effective circulating blood volume and causing chills throughout the body. Drinking more water helps provide sufficient hydration and maintain normal bodily fluid balance. In cases of severe dehydration, fluids such as glucose injection or glucose-sodium chloride injection may be administered intravenously under medical supervision to rapidly restore lost fluids.

3. Take medication

If there is no significant improvement in condition, body temperature should be measured with a thermometer. When body temperature exceeds 38.5°C, it is recommended to take medications such as acetaminophen tablets or ibuprofen sustained-release capsules under medical guidance.

In addition, symptoms may also be relieved through mild physical activity. If fever recurs, prompt medical evaluation is necessary for further examination, accurate diagnosis, and appropriate treatment.
