Adults with stressful thoughts do not directly cause thrush, which is caused by Candida infection. However, stressful thinking tends to affect the body’s immune function, which in turn increases the likelihood of the disease. Thrush, also known as acute pseudomembranous candidiasis, is caused by Candida infection. Candida can be parasitized in the oral cavity, vagina and other parts of the body, and maintains a symbiotic balance with other microorganisms in the body. Normally, it does not cause disease. But once the body’s immunity is lowered, it will trigger the disease. For example, adults with excessive stress, often stay up late, poor oral hygiene, or suffering from diabetes, AIDS, oncological diseases and other underlying diseases, can lead to a decline in the patient’s immunity, increasing the risk of morbidity. Normally, greater mental stress should be avoided, and active participation in social activities and physical exercise should be encouraged in order to soothe the mood. If thrush occurs, you should also seek medical examination and symptomatic treatment as soon as possible.
