Warm season often refers to a period of winter or cold climate. During this period, due to the low temperature, people easily feel cold and their bodies are more sensitive to changes in the external environment. In the warm season, people will take a series of measures to ensure that they can resist the cold and keep healthy. For example, wearing suitable thick clothes, strengthening exercise to raise body temperature and choosing warm food in diet are all common methods. These measures help to promote blood circulation, enhance the body's resistance, and reduce the frequency of various discomforts or diseases caused by low temperature.
