It is inaccurate to say that drinking more hot water is a cure for colds, but drinking more hot water for colds is good for recovery.
Hot water is not a medicine, so it does not have antiviral or other related effects, nor does it have the effect of treating colds, so the claim that drinking more hot water can cure colds is also inaccurate.
However, patients with colds may suffer from decreased appetite and water intake, and may also lose water due to increased evaporation of water caused by fever, or sweating more after using antipyretic medication. Therefore, drinking more hot water appropriately will be beneficial for the recovery of the condition.
Cold and flu patients need to pay attention to the hot water when drinking hot water at the right temperature.
