Understanding Health

n exploration of the physiology of walking, explaining how posture, balance, breathing, joint alignment, and muscle coordination help the body stay upright and move efficiently without strain.

The Physiology of Biological Time Human physiology is organized around a near-24-hour cycle known as the circadian rhythm. This internal timing system regulates sleep–wake patterns, hormone secretion, metabolism, immune function, tissue repair, and nervous system tone. Circadian rhythms are endogenous — generated within the body — but they are synchronised to the external environment, primarily through light. central clock in the brain (SCN) connected to peripheral organs  T

Sympathetic and Parasympathetic Balance in Yoga Modern physiology explains balance in terms of the sympathetic  and parasympathetic  branches of the autonomic nervous system . Health depends not on suppressing either branch, but on their rhythmic alternation across the day. Traditional yogic physiology describes this same alternation using the language of sun (surya)  and moon (chandra) . These are not metaphors layered onto physiology; they are functional categories derived

Resistant starch shifts digestion away from the small intestine and toward the colon, it lowers insulin demand, smooths glucose curves, and supports long-term insulin sensitivity.

The Science of Resistant Starch (RS) Starch is a complex carbohydrate made of glucose units. During digestion, enzymes—mainly amylase from saliva and the pancreas—break starch into smaller sugars, ultimately glucose, which is absorbed from the small intestine into the bloodstream. However, not all starch is digested this way. The fraction that escapes digestion in the small intestine is known as resistant starch (RS) . As the name suggests, resistant starch “resists” enzymati

The body does not absorb nutrients merely because they are swallowed. Absorption depends on digestion, metabolic readiness, muscle use, and internal balance.

The vagus nerve links brain, organs, and autonomic balance. This article explains its integrative role, why the nervous system is not a switch, and what vasovagal responses reveal.

Stretching is not simply about lengthening muscles. It is a neurological process shaped by proprioception, muscle coordination, and nervous system safety. This article explores what truly happens in the body when we stretch, and why gentle, informed engagement leads to lasting ease.

Irritable bowel syndrome is a common digestive condition marked by disturbed rhythm rather than visible disease. This article explores what becomes “irritated” in IBS, how digestion and elimination lose coordination, why hunger cues become unreliable, and how restoring digestive rhythm supports long-term gut stability, especially with ageing.

In the earlier article , digestion was described as a coordinated process rather than a mechanical one. This perspective becomes especially relevant when examining foods that are considered “light” or universally suitable. Morning fruit is one such case—often beneficial, sometimes disruptive—depending not on the food alone, but on the state of digestion at the time it is eaten. Though eating fruit first thing in the morning is often described as “light,” for some people, thi

The mouth is one of the body’s most sensitive gateways to the environment. Understanding sublingual absorption helps place many traditional and modern practices in context.
