The Role of the Sympathetic Nervous System in Physiological Responses and Physical Activity

When we laugh or run for sport which autonomic system works?

When we laugh or engage in physical activities like running for sport, the autonomic nervous system responsible for these actions is the sympathetic nervous system. The sympathetic nervous system is a part of the autonomic nervous system, which controls involuntary bodily functions.

During laughter, the sympathetic nervous system is activated. It triggers a series of physiological responses, such as increased heart rate and blood pressure, dilation of the bronchioles in the lungs for increased oxygen intake, and the release of stress hormones like adrenaline. These responses prepare the body for action and are often associated with the fight-or-flight response.

Similarly, when we run for sport or engage in any form of physical exercise, the sympathetic nervous system is also activated. It helps mobilize the body’s energy resources and prepares it for increased physical exertion. This includes increasing heart rate, redirecting blood flow to the muscles, increasing respiration rate to supply more oxygen to the tissues, and the release of adrenaline for a boost of energy.

The sympathetic nervous system functions in contrast to the parasympathetic nervous system, which is responsible for activities that promote relaxation and conservation of energy, such as digestion and resting. These two systems work in balance to regulate various bodily functions and maintain homeostasis in response to different situations.
