Patients with cold body constitution or cold in the uterus are more likely to experience infertility. Therefore, if one has a cold body constitution, it is important to adjust it promptly. Usually, you can eat some foods that eliminate coldness in the body, such as adzuki beans and coix seeds. Engaging in more physical exercise and sweating can also help expel the coldness through sweat. Alternatively, soaking in warm water, sauna treatments, cupping therapy, and moxibustion are effective methods for expelling internal coldness. These can improve symptoms of a cold constitution and spending more time in the sunlight can also boost the body's immunity.
