The reason people often feel better after vomiting is mainly due to the body's release of endorphins, which are natural chemicals that help reduce stress and create a sense of relief or even euphoria. Vomiting also physically expels whatever is causing the upset or nausea in the stomach, which is the direct source of discomfort. When the body detects and removes this harmful or irritating substance, it signals the brain to relax, lowering stress levels and blood pressure, which contributes to feeling better. Additionally, the vagus nerve is involved in this process and might also help reduce pain or nausea after vomiting. In summary:
- Vomiting expels whatever is upsetting the stomach.
- The body releases endorphins, which reduce pain and stress, making a person feel better.
- The physiological reaction after vomiting, including relaxation of the body and possible changes in blood flow, helps reduce nausea or discomfort.
- This process explains why some people feel relief or even a "high" after vomiting.
This relief is why some people even induce vomiting when feeling very nauseous, although it is not generally advisable to do so unless medically necessary.
