Can soaking feet in warm water treat a heat-type cold?
Generally, soaking feet in warm water can alleviate symptoms of a heat cold to some extent, but it cannot cure a heat cold. The detailed explanation is as follows:

Soaking feet in warm water can promote blood circulation, accelerate metabolism, and help relieve fatigue and muscle pain caused by a heat cold. At the same time, this practice can also help improve sleep quality, allowing patients to rest better, thus enhancing immunity and speeding up the recovery process. Additionally, soaking feet in warm water can promote perspiration and help the body dissipate heat, thereby relieving fever caused by a heat cold. In general, while heat cold patients are receiving medication treatment as directed by a physician, warm foot baths can be used as an adjunctive therapy.
However, soaking feet in warm water cannot replace formal medical treatment. A heat cold may be caused by bacterial or viral infections, and if symptoms are severe or persist for a prolonged period, prompt medical attention should be sought, and treatment should follow the doctor's recommendations.
In daily life, it is recommended to maintain good hygiene habits, eat a balanced diet, and engage in appropriate exercise to enhance one's resistance and help prevent heat colds.
