Dietary adjustments: People with yang deficiency should eat less ice water, ice cream, ice cream and other cold foods. At the same time, you can eat some of the warm nature of mutton, jujube, wolfberry and so on to regulate. 2. Taking medicines: Right Angelica Pill, Radix Rehmanniae Medica Soup and other formulas have the effect of warming the middle of the body to strengthen the spleen and tonifying the kidney yang (warming and replenishing the kidney yang qi), so you can use medicines as appropriate to regulate your body under the guidance of your doctor. 3. Pay attention to lifestyle: people with spleen and kidney yang deficiency should get more sunshine and pay attention to exercise. People’s own lack of yang qi leads to the stagnation of cold, if you stay indoors or even air-conditioned rooms for a long time, it is not conducive to the dispersion of cold. It is recommended that people who do not sweat in the heat of the day go to the hospital in a timely manner and be treated under the guidance of a doctor.
