The parasympathetic nervous system (PSNS) is a network of nerves that helps regulate the activity of the heart and other organs. It is part of the autonomic nervous system, and plays a key role in maintaining homeostasis, or the body’s natural balance. When the body is in a relaxed state, the PSNS is active. The most common result of parasympathetic stimulation is a decrease in heart rate. However, there are other effects of parasympathetic stimulation, and in this article, we’ll explore which of the following is not a result of parasympathetic stimulation.
- Increased Heart Rate: Contrary to popular belief, parasympathetic stimulation does not always increase heart rate. The most common result is a decrease in heart rate, as the PSNS causes the body to relax and the heart to slow down.
- Enhanced Cognition: Parasympathetic stimulation does not necessarily improve cognition. While it does help regulate the body’s natural balance and can have a calming effect on mental processes, it does not directly increase cognitive functioning.
- Reduced Anxiety: While parasympathetic stimulation may help reduce anxiety, it is not the only factor that is involved. Other factors such as lifestyle, diet and exercise, as well as environmental factors can influence anxiety levels.
- Heightened Stress Response: Surprisingly, this is the answer to our question. Parasympathetic stimulation does not cause the body to become more stressed, as one might expect. In fact, it usually has the opposite effect and helps the body relax.
Overall, parasympathetic stimulation is an important part of the autonomic nervous system, and has a range of effects on the body. While the most common result is a decrease in heart rate, heightened stress response is not a result of parasympathetic stimulation.
