There are many reasons why the lower body is dry, as follows: 1. Consider whether it is vaginal inflammation, because vaginal inflammation can cause ulceration of the vaginal wall and local bleeding, which can easily affect the secretion of some secretions and therefore produce the phenomenon that the lower body is dry; 2. Changes in the hormone level in women’s bodies can also have an impact on women’s secretions. In order to improve the phenomenon of vaginal dryness, it is recommended to eat more hormone-rich soy products, such as black beans and soybeans, and drink more soy milk. You can also regulate the endocrine secretion of your body by exercising. Doing aerobic exercises such as yoga and jogging can regulate the hormonal changes in your body, promote the growth of hormones in your body and improve the symptoms of dryness down there.
