In winter, some elderly people and women are prone to cold hands and feet, which is usually related to insufficient yang energy and weak circulation of qi and blood. You can appropriately eat more food that can nourish qi and blood, such as mutton, red dates, black bone chicken, longan, pig liver, dangshen, astragalus, angelica, ass hide glue, etc. In addition, according to personal taste, some warm yang tonifying and cold dispersing foods can be paired, such as ginger, onions, white atractylodes, pepper, etc. Common methods include stewing black chicken with Codonopsis pilosula and red dates, pork belly soup with pepper, and lamb soup with Angelica sinensis. People with insufficient qi and blood often feel weak. A simple method is recommended - taking a walk while sunbathing on the shoulders and back when there is sufficient sunlight. This can help the human skin produce vitamin D, promote the absorption of calcium in the intestines, and help prevent osteoporosis. You can also apply moxibustion to acupoints on the Du meridian, or choose specific acupoints on specific meridians according to your own situation. For example, people with poor spleen and stomach can choose the Zusanli acupoint, those who are prone to dysmenorrhea can choose the Guanyuan acupoint, those who are afraid of cold and weak legs and feet can use the Yongquan acupoint, and those who are afraid of wind on the shoulders and neck can use the Dazhui acupoint, etc., which can warm up yang and tonify qi, warm meridians and dispel cold, and improve the body's cold resistance and disease resistance. In addition, soaking Ai Ye, Chuanxiong, and Fangfeng in water and soaking them in feet can also warm up yang, dispel cold, and promote the circulation of qi and blood. (New Society)
