 Concussions can have a significant impact on the autonomic system, which controls the body’s automatic functions like heart rate and breathing. Studies have found that concussions can cause disruptions in the autonomic system, leading to symptoms like dizziness, nausea, and changes in heart rate. This connection highlights the importance of proper concussion management and monitoring to prevent long-term effects on the autonomic system.
