Introduction
Anxiety affects millions worldwide, often disrupting daily life. While traditional treatments like therapy and medication remain essential, alternative techniques have gained traction for their ability to provide quick relief. One such unconventional yet scientifically backed method involves covering your left eye and looking up—an approach that engages brain lateralization to regulate stress.
Even more intriguing is how this technique connects to vagus nerve stimulation devices, which are known for their role in promoting relaxation by activating the parasympathetic nervous system. Additionally, cannabis has been widely recognized for its calming effects, making it a powerful complement to these techniques. This article explores how this eye-covering trick works, its link to the vagus nerve, and how cannabis enhances its effectiveness in anxiety relief.

How Covering One Eye and Looking Up Helps with Anxiety Relief
Brain Lateralization and Anxiety Regulation
The human brain is divided into two hemispheres, each playing a role in emotional processing:
Left Hemisphere: Controls logic, structured thinking, and relaxation.
Right Hemisphere: Governs emotion, intuition, and fear responses.
Each eye primarily sends signals to the opposite hemisphere:
Right Eye → Left Hemisphere (logic, calmness)
Left Eye → Right Hemisphere (emotions, anxiety)
Since anxiety often stems from an overactive right hemisphere, covering the left eye forces the brain to rely on the rational left hemisphere, helping to suppress excessive fear responses.
Why Looking Up Matters
Eye positioning directly influences cognitive function. Studies suggest that looking upward activates the prefrontal cortex, a brain region responsible for decision-making and emotional control. Additionally, it enhances alertness and counters the downward gaze commonly associated with anxiety and overthinking.
How the Vagus Nerve Stimulation Device Enhances This Technique
The vagus nerve stimulation device (VNS device) is designed to regulate nervous system activity, reducing stress by activating the parasympathetic response. Since the vagus nerve plays a critical role in calming the body, using a VNS device while practicing the eye trick may enhance relaxation by:
Reducing heart rate and blood pressure
Decreasing cortisol (the stress hormone)
Improving overall emotional stability
Using a vagus nerve stimulation device in combination with this technique can amplify the calming effect, making it an effective biohacking method for anxiety relief.

How Cannabis Affects Anxiety and Brain Function

Tying Cannabis Into the Equation: How It Enhances Vagus Nerve Stimulation
Cannabis and the Vagus Nerve
The endocannabinoid system (ECS) works closely with the vagus nerve to regulate mood and stress. Cannabis, particularly CBD, has been shown to influence vagus nerve activity, leading to increased relaxation and reduced anxiety.
Key cannabinoids and their effects:
THC (Tetrahydrocannabinol): At low doses, THC can reduce anxiety, but higher doses may trigger paranoia. Proper dosing is crucial.
CBD (Cannabidiol): Interacts with serotonin and GABA receptors, promoting calmness without intoxication.
Combining Cannabis with Vagus Nerve Stimulation Devices
Pairing a vagus nerve stimulation device with cannabis may optimize stress relief by:
Enhancing parasympathetic activation
Reducing hyperactivity in the amygdala (the brain’s fear center)
Promoting deep relaxation and mental clarity
The Role of the Vagus Nerve in Anxiety and Stress Relief
The vagus nerve is the body's natural stress regulator, influencing:
Heart rate and blood pressure
Digestion and gut health (often disrupted by stress)
Mood and emotional stability
Methods that stimulate the vagus nerve include deep breathing, meditation, cold exposure, and now, vagus nerve stimulation devices.
How the Eye Trick and a Vagus Nerve Stimulation Device Work Together
Looking Up + Eye Covering: Engages brain hemispheres and reduces right-brain dominance, alleviating anxiety.
Vagus Nerve Stimulation Device: Enhances parasympathetic activation, reducing stress-related symptoms.
Cannabis: Further promotes relaxation by modulating neurotransmitters and vagus nerve function.
This three-pronged approach could be a game-changer for those struggling with anxiety and looking for non-pharmaceutical interventions.
How to Try This for Yourself
Find a quiet space and get comfortable.
Cover your left eye with your hand while keeping your right eye open.
Look upward for 10-20 seconds while breathing deeply.
Observe any mental shifts—do you feel a decrease in anxiety?
Use a vagus nerve stimulation device simultaneously to enhance relaxation.
(Optional) If cannabis is legal and appropriate for you, consider a low dose of CBD or THC before trying the technique.
Important Note: Consult a healthcare professional before using a vagus nerve stimulation device or cannabis, especially if you have underlying medical conditions.
Conclusion: A Powerful, Science-Backed Anxiety Hack
By combining the one-eye trick, a vagus nerve stimulation device, and cannabis, individuals can harness a science-backed, holistic approach to anxiety relief. These techniques align with known principles of brain lateralization, vagus nerve activation, and endocannabinoid system regulation, offering a natural and effective way to regain calm and control.
For those looking to explore alternative anxiety management, this method is worth trying—especially when paired with a vagus nerve stimulation device to maximize relaxation and stress resilience.
