How does slow breathing affect the nervous system?

Impact on the Autonomic Nervous System

Slow breathing has a direct impact on the autonomic nervous system, specifically the parasympathetic branch. It helps activate the body's natural relaxation response, also known as the 'rest and digest' mode. By taking slow, deep breaths, you signal to your body that it is safe, which in turn reduces stress hormones and promotes a sense of calmness.

Stimulation of the Vagus Nerve

When you engage in slow breathing, you stimulate the vagus nerve, a key component of the parasympathetic nervous system. This stimulation leads to the release of neurotransmitters like acetylcholine, which further promotes relaxation and reduces heart rate. The vagus nerve plays a crucial role in regulating various bodily functions, including heart rate, digestion, and mood.

Reduction of the Fight-or-Flight Response

By incorporating slow breathing into your routine, you can effectively dampen the fight-or-flight response triggered by stressful situations. This shift from a sympathetic state to a parasympathetic state can help lower blood pressure, decrease muscle tension, and improve overall emotional regulation. Slow breathing acts as a powerful tool to counteract the negative effects of chronic stress on the body.
