Endocrinology of Aging
Neuroendocrinology is physiology of the hypothalamus and its control over secretions of hypothalamic and pituitary glands. Hypothalamus maintains homeostasis, regulates reproduction, metabolism, eating and drinking behaviour, as well as energy utilization, osmolarity and blood pressure. Releasing Factors from hypothalamus triggerStimulating Factors from the Master Gland – the Pituitary). They next find Receptors on epithelial cells of a collection of peripheral endocrine glands: thyroid, parathyroid, adrenals, endocrine pancreas, and sex glands of ovary and testes; they in turn releaseModified Spiritualized (pranayamic) hormones directly into the circulation.
Impact of regular pranayama on the brain and endocrine system has a favorable rejuvenating effect on health and fitness of body and mind. Ancient yogic texts advocate perfection of the body and faultlessness of mind. Today however, yoga is popular as a system of practical discipline to improve physical, physiological, psychological, and spiritual health. Human growth hormone (GH) secreted from anterior pituitary has important roles in growth of almost all tissues, metabolism, and changes in body composition. Dehydroepiandrosterone sulphate (DHEAS) secreted by the adrenal cortex, acts in the human body as a neurosteroid, cardioprotective, antidiabetic, antiobesity, and immunoenhancing agent: GH and DHEAS are reported as youth hormones (Sridip Chatterjee and Samiran Mondal).
Basal levels of GH and DHEAS decline with advancing age. The anti-aginghormones GH and DHEAS show a slower decline in active individuals than in their inactive peers. Regular exercise habit encourage the secretion pattern of GH and DHEAS throughout the lifespan. Yogic training in pranayama therefore slows aging dramatically.
