During the period of fever reduction, the patient may sweat a lot due to heat dissipation, and it is necessary to pay attention to the weakness of the patient after losing a lot of water during this period. Therefore, it is not recommended for patients to get out of bed during this period, and if they want to get up, they need to be supported by family members to prevent accidents such as falls. At the same time, a large amount of fluid needs to be replenished to hydrate the body. For patients who cannot cooperate with oral intake, intravenous rehydration can be considered to replenish the water and electrolytes lost by the body. It is also necessary to keep clothes dry, because during the period of fever reduction, due to the large amount of sweating, the patient’s clothes may appear soaked, and this time need to be changed in time to prevent wet and cold clothes against the body after the possibility of re-cold. At the same time, outdoor activities should be reduced as much as possible to avoid getting cold again caused by open wind, which may lead to aggravation of the disease.
