How Does Optimising The Vagus Nerve Result To Better Sleep?
The vagus nerve is intricately connected to sleep regulation through its role in promoting the parasympathetic response, also known as the “rest and digest” mode (2). When the vagus nerve is activated it helps counterbalance the sympathetic nervous system’s “fight or flight” response, signaling the body to relax and prepare for sleep. The vagus nerve influences factors such as heart rate variability and respiratory patterns, contributing to overall sleep quality.
What is the Vagus Nerve?
The vagus nerve is also known as the tenth cranial nerve (CN X). It is a critical component of the parasympathetic nervous system. It is the longest of the cranial nerves and plays a crucial role in regulating various bodily functions, including heart rate, digestion, and respiratory rate. The vagus nerve serves as a bidirectional communication highway between the brain and several organs, influencing the body’s rest-and-digest response. How then can the vagus nerve contribute to having a sound sleep?
What Are Relaxation Techniques?
Relaxation techniques are the various methods designed to alleviate stress, promote a sense of calm, and induce a state of relaxation in both the mind and body. These practices are useful for managing stress, and anxiety, and improving overall well-being. Here are some common relaxation techniques:
How Can You Improve Sleep with Vagus Nerve Exercises?
Improving sleep with vagus nerve exercises involves engaging in activities that stimulate the vagus nerve, a key component of the parasympathetic nervous system. By activating the vagus nerve, you can enhance the body’s rest-and-digest response, leading to improved sleep quality. Here’s how you can incorporate vagus nerve exercises into your routine:
- Breathing Exercises
Engaging in breathing exercises can tremendously improve one’s quality of sleep. Here are some of the exercises that can be carried out; - Deep and Slow Breathing:
This is usually done by Inhaling slowly through your nose, and expanding your diaphragm. Then exhale slowly through your mouth, allowing your abdomen to contract. Repeat this technique for several breath cycles. - Diaphragmatic Breathing:
This method of breathing is done by focusing on breathing deeply into your diaphragm rather than shallow chest breathing. Place your right hand on your chest and your left hand on your abdomen to ensure abdominal movement. - 4-7-8 Technique
Inhale through your nose without making a sound for a count of 4, hold your breath and count 7, then exhale through your mouth for a count of 8 - Box Breathing: Inhale for a count of 4, hold your breath for 4 counts, exhale for 4 counts, and pause for another 4 counts before repeating.
What Are The Types of Yoga Poses for Better Sleep?
- Child’s Pose (Balasana):
This grounding pose gently stretches your hips, thighs, and ankles. It encourages a sense of surrender, allowing your mind to release tension thereby promoting relaxation before bedtime.
Procedure
⦁ Kneel on the mat, sit back on your heels, and extend your arms forward with your forehead resting on the mat. This pose stretches the back and promotes a sense of surrender, calming the mind. - Legs Up the Wall (Viparita Karani):
This technique is particularly beneficial for reducing anxiety and promoting a restful state. It is done by sitting close to a wall and lying on your back while extending your legs up against the wall. By inverting the legs against the wall, this pose enhances blood circulation and calms the nervous system. - Corpse Pose (Savasana):
Savasana is the ultimate relaxation pose. As you lie down with extended limbs and practice conscious breathing, the body enters a state of complete rest. It helps quiet the mind and release any residual tension.
Procedure
⦁ Lie on your back, extending your arms and legs with your palms facing up. Focus on deep, mindful breathing, allowing the body to release tension and enter a state of relaxation. - Seated Forward Bend (Paschimottanasana):
This forward bend gently stretches the spine, hamstrings, and lower back. It promotes a calming effect on the nervous system, making it a valuable addition to a bedtime yoga routine.
Procedure
⦁ Sit with legs extended, hinge at the hips, and reach for your toes. - Reclining Butterfly Pose (Supta Baddha Konasana):
By opening your hips and allowing your knees to fall outward, this pose facilitates a deep sense of surrender. It is effective in releasing tension from the groin and inner thighs.
Procedure
⦁ Lie on your back, bring the soles of your feet together, and allow your knees to fall outward. - Supported Bridge Pose:
This gentle backbend pose encourages relaxation and prepares the body for sleep.
Procedure
⦁ Lie on your back, bend your knees, and lift your hips, placing a block or cushion beneath your sacrum. This supported backbend relieves tension and calms the mind.
Mindfulness Practices
Mindfulness meditation involves cultivating a heightened awareness of the present moment. Find a quiet space, sit comfortably, and focus your attention on your breath. Observe the natural flow of your inhalations and exhalations without judgment. If your mind wanders, gently redirect your focus to the breath. This practice helps anchor your attention to the present, fostering a sense of calm and reducing mental chatter that may interfere with sleep.
As you engage in mindfulness meditation, bring your awareness to the rhythmic cycle of breathing. Notice the sensation of the breath entering and leaving your body. Additionally, pay attention to any bodily sensations or tensions. Scan your body from head to toe, acknowledging areas of tightness or relaxation. This heightened awareness promotes a connection between the mind and body, encouraging relaxation and setting the stage for restful sleep.
Another thing to note is that Mindfulness activities activate the vagus nerve since the vagus nerve plays a crucial role in the body’s relaxation response. Mindfulness activities, including meditation, stimulate the vagus nerve, initiating the parasympathetic nervous system’s rest-and-digest mode. When the vagus nerve is activated, it releases acetylcholine, a neurotransmitter that promotes a state of tranquility. This activation not only soothes the mind but also has a calming effect on the body, reducing heart rate and promoting overall relaxation.
Self-Massage Techniques
Regular massages, whether administered by a professional or by yourself through a self-massage, offer a range of benefits for your relaxation and well-being. Professional massages typically involve the use of various techniques, including Swedish or deep tissue massage, to target muscle tension and promote overall relaxation. If professional massages are not accessible, incorporating self-massage techniques can be a practical and effective alternative.
This can be done by putting gentle pressure on specific areas of the body to activate the vagus nerve. The vagus nerve, when stimulated, releases neurotransmitters that induce a state of calm. This response includes a decrease in heart rate, improved digestion, and a reduction in the body’s stress hormone levels. The overall effect is a profound sense of relaxation and tranquility
Key areas for self-massage to activate the vagus nerve include:
- Neck: Gently massaging the sides and back of the neck can stimulate the vagus nerve, promoting relaxation.
- Face: Applying light pressure to the temples, jawline, and forehead can have a calming effect.
- Chest: Gentle massage around the chest area, particularly over the sternum, can activate the vagus nerve.
- Ear: the tragus and cymba concha regions of the ear. Contrary to Hollywood movies the ear lobe is not effective.
Acupressure Points for Sleep
Acupressure, akin to a needle-free version of acupuncture, involves applying pressure to specific points on the body to stimulate sensory nerves and release natural chemicals (5). Unlike acupuncture’s use of needles, acupressure utilizes finger, thumb, or knuckle pressure, and it can even be performed using blunt objects like a pen. While health professionals can administer acupressure, it’s also a safe and accessible practice for self-application.
The technique is believed to trigger the release of endorphins, which are natural pain-relieving chemicals, offering potential relief from discomfort (4). Additionally, acupressure has been associated with addressing digestive issues and enhancing the quality of sleep.
Here are some acupressure points to induce sleep;
- Third Eye Point (GV24.5):
Located between the eyebrows, this point is associated with calming the mind. Gentle pressure here may relieve stress and promote relaxation for better sleep. - Spirit Gate (HT7):
