Coldness starts from the feet.

When the weather is cold, there's nothing better than snuggling under the covers to keep warm. However, some people experience cold hands and feet even in the hottest weather. An old saying goes, "Cold starts from the feet, heat dissipates from the head," which simply means that to warm the body, you must first warm the feet, and to dissipate heat, the head will sweat first. This highlights the undeniable importance of keeping your feet warm. The "Treatise on Cold Damage" once stated: "Whenever there is jue, it is due to the disharmony of yin and yang qi. Jue refers to cold hands and feet." In Traditional Chinese Medicine (TCM), cold hands and feet are also known as "jue coldness of hands and feet." When the yin and yang qi and blood are unbalanced, and qi and blood fail to reach the extremities, it results in cold hands and feet. When the weather is cold, blood circulation and foot warmth are particularly important. Although the feet are furthest from the heart, they are rich in blood vessels, nerves, and reflex points corresponding to the five zang organs and six fu organs. On a daily basis, you can steep four roses, four pitted red dates, four dried longans, and two slices of ginger in hot water for ten minutes and then drink it. This tea is warm in nature and helps invigorate qi and strengthen the spleen, promoting blood circulation. Note: This drink is not suitable for those with colds and coughs. Roses, sweet and warm in nature, can nourish blood and qi, beautify skin, promote blood circulation, and balance endocrine. Red dates, sweet and warm in nature, strengthen the spleen and stomach, and can replenish insufficient qi and blood. Dried longans, sweet and warm in nature, can benefit the heart and spleen, stimulate appetite and strengthen the spleen, nourish blood and calm the mind, strengthen yang and invigorate qi, and nourish deficiency and enhance intelligence. Ginger, pungent and warm in nature, enters the lung, spleen, and stomach meridians. It can warm the lungs and stop coughs, induce sweating to release the exterior, alleviate symptoms of common cold, and regulate spleen and stomach deficiency and cold. Additionally, at night, you can soak your feet in warm water (around 40 degrees Celsius) with some ginger slices. This helps promote blood circulation, improve cold hands and feet, and can also aid in sleep.
