The link between Breath and Nervous System – Foundation of Pranayama

The link between Breath and Nervous System – Foundation of Pranayama

In this post, we will discuss the link between the breath and mind – which forms the foundation of Pranayama, the fourth limb of Ashtang Yoga (Ashtang means 8 limbs in Sanskrit) as formulated by the Lord Patanjali in his Yoga Sutra. There are different schools of thought in defining the mind. According to Yogic texts, the mind is the awareness of consciousness. The consciousness is itself is an unexplored subject when it comes to neuroscience. Hence, for simplicity, we…

Neurotransmitters and Diseases – Neuroscience Perspective

Neurotransmitters and Diseases – Neuroscience Perspective

There are approximately 80 billion neurons in the human nervous system interconnected through trillions of synapses. These neurons communicate with one another, and with muscle cells and gland cells, by releasing chemical messengers called “Neurotransmitters”. These neurotransmitters are involved in countless functions of the nervous system and in controlling bodily functions. They play a major role in the functioning of the body in everyday life. There are also other chemicals in the body called “Hormones” that are produced by the…

Neuroscience Evidence of Benefits of Yoga on Brain Health

Neuroscience Evidence of Benefits of Yoga on Brain Health

A recent study conducted by the University of Illinois at Urbana Champaign and Wayne State University indicates that Yoga has a positive effect on the structure and function of key brain areas associated with memory. The findings provide evidence that yoga may hold promise in mitigating the age-related and neurodegenerative decline. The practice of Yoga originated and developed over many thousands of years by sages in ancient India, is known to have a positive effect on body and mind. Yoga…

Why is Sleep important – a Neuroscience Perspective

Why is Sleep important – a Neuroscience Perspective

Good quality sleep is vital to the health of the body and mind. Adults need 7 to 8 hours of sleep at night while adolescence needs around 9 to 10. We are just beginning to understand through Neuroscience why we need sleep. Sleep deprivation or poor-quality sleep can lead to disorders. It can be as simple as irritability, fatigue, and loss of concentration in the short-term. Long-Term sleep deprivation can lead to immune system related disorders (like inflammation, autoimmune diseases),…

Yoga Stimulates Vagus Nerve to Induce Relaxation Response – a key to Emotional Health

Yoga Stimulates Vagus Nerve to Induce Relaxation Response – a key to Emotional Health

Vagus Nerve is the largest cranial nerve in the body. It starts at the base of the skull and runs throughout the whole body. It plays a central role in your emotional and physical health. It directly influences the nervous system – particularly the Parasympathetic branch of the Autonomic Nervous System (covered in a previous post). Our breath, heart rate, and digestion — as well as our overall ability to experience the world (particular how to handle the stress in…

Do you know we humans have a second brain – The Enteric Nervous System

Do you know we humans have a second brain – The Enteric Nervous System

Medically known as ‘Enteric Nervous System’, our so-called second brain is a part of the Autonomic Nervous System. It consists of sheaths of 100 million neurons embedded in the walls of our digestive tract (alimentary canal) from the esophagus to the anus. It has its own reflexes and senses, and can behave independently of the brain for the process of digestion and excretion. The business of digestion is delegated to this nervous system in our gut. It controls the involuntary…

Why Yoga helps in Post-Traumatic Stress Disorder (PTSD)

Why Yoga helps in Post-Traumatic Stress Disorder (PTSD)

The restorative yoga poses bring back the homeostatic balance caused by trauma. This can be very helpful to a person suffering from Post-Traumatic Stress Disorder (PTSD). Under a sustained experience of trauma, the stress hormone called ‘Cortisol’ is consistently overproduced. It eventually causes the desensitization of the HPA axis. Because of this the nervous system no longer responds to the normal homeostatic feedback loop that otherwise in a normal course causes it to “calm down”. This means the HPA axis…
