Blood Sugar
Support healthy blood sugar levels through nervous system regulation
Stress and blood sugar are directly linked through cortisol — the stress hormone that signals the liver to release glucose into the bloodstream. Chronic sympathetic activation keeps cortisol elevated, contributing to persistently elevated blood sugar and insulin resistance. Breathing exercises that activate the parasympathetic nervous system reduce cortisol output, supporting more stable blood sugar levels throughout the day.
The timing of breathing practice matters for blood sugar management. A 5-minute coherence breathing session after meals enhances the rest-and-digest parasympathetic state that optimizes digestion and insulin response. Studies show that parasympathetic activation during the post-meal period improves glucose uptake and reduces post-meal blood sugar spikes — a key target for metabolic health.
For people managing prediabetes or type 2 diabetes, daily breathing practice addresses one of the most overlooked contributors to blood sugar dysregulation: chronic stress. While breathing exercises do not replace medication or dietary management, they provide a meaningful additional lever for blood sugar control that costs nothing and has no side effects.
Benefits
- Reduces cortisol-driven glucose release
- Improves post-meal insulin response
- Activates rest-and-digest state for optimal metabolism
- Addresses stress component of blood sugar dysregulation
- Complements dietary and medical management
Frequently Asked Questions
Can breathing exercises lower blood sugar?
Breathing exercises reduce cortisol, which reduces stress-driven glucose release from the liver. They also improve parasympathetic tone during digestion, which supports better insulin sensitivity. The effect is supportive rather than primary — complement rather than replace medical management.
When should I practice for blood sugar benefits?
After meals is the most impactful timing. A 5-minute coherence breathing session after eating enhances the parasympathetic state that optimizes insulin response and glucose uptake, reducing post-meal blood sugar spikes.
How much improvement can I expect?
Individual results vary, but studies on stress-reduction interventions show modest improvements in fasting glucose and HbA1c when practiced consistently. Breathing exercises work best as part of a comprehensive approach including diet, exercise, and medical management.
