Can rice wine lees improve cold hands and feet?

In general, fermented rice (Laozao) can somewhat improve the condition of cold hands and feet. The detailed explanation is as follows:

After fermentation, Laozao contains a small amount of alcohol, which can promote blood vessel dilation and accelerate blood circulation, allowing blood to flow more smoothly to extremities such as hands and feet, thus alleviating the cold sensation caused by poor circulation. Additionally, consuming warmed Laozao produces a distinct warming effect, which helps dispel internal coldness and is especially suitable for individuals with cold constitutions during cold seasons. Moreover, the sugars and nutrients in Laozao provide energy to the body and enhance its heat-producing capacity, indirectly helping to improve cold hands and feet.

When consuming Laozao to improve cold extremities, it is recommended to warm it before consumption to avoid gastrointestinal discomfort caused by cold intake. Each serving should not be excessive—half a small bowl is sufficient—to prevent excessive alcohol intake. Individuals allergic to alcohol, pregnant women, and children should avoid its consumption. If symptoms such as dizziness, palpitations, or gastrointestinal discomfort occur after consumption, usage should be stopped immediately and physical reactions monitored. For individuals experiencing severe or persistent coldness in the extremities, additional调理 (regulating) methods should be adopted, rather than relying solely on Laozao.
