Yoga training is known to achieve a stable autonomic balance, a relative hypometabolic state
, and improvement in physical efficiency.
Invasive diagnostic procedures if not deemed life-saving should be postponed because of a higher risk of complications caused by impaired coagulation and hypometabolic state
[1, 2] Hypothyroidism induced decreased metabolism can lead to decreased tissue need for oxygen as an adaptation to hypometabolic state
leading to inadequate erythropoietin stimulation resulting in anaemia.
Luteal phase deficiency in recreational runners: evidence for a hypometabolic state
. J Clin Endocrinol Metab.
Practice of meditation along with pranayama produces a hypometabolic state
 of the body characterized by decreased carbon dioxide production and decreased oxygen consumption, thus allowing breath holding for a longer time.
Wallace, Benson, and Wilson (1971) were among the first to identify this unique physiological state, which they called "a wakeful hypometabolic state
Low body temperature, depression, and chronic fatigue indicate a hypometabolic state
not unlike that of hypothyroidism (1-2).
The hypothesis for the present research was that regular experience of the wakeful hypometabolic state
produced by the Transcendental Meditation program develops general cognitive ability (Alexander et al., 1990; Dillbeck & Alexander, 1989; Orme-Johnson, Zimmerman, & Hawkins, 1997; So, 1995).
Significant losses in body weight place the body in a hypometabolic state
in which the total amount of calories required is decreased.
The hypometabolic state
of hypothyroidism can cause reduction in glycolysis and oxidative phosphorylation and thus reducing Adenosine Triphosphate (ATP) concentrations.
The free radical accumulation in hypothyroidism can be due to atherogenic hyperlipidaemia providing substrate for increased lipid peroxidation, decreased clearance of oxidants due to hypometabolic state
and poor defence mechanism against free radicals by antioxidants.
This should bring about a hypometabolic state
resulting in decreased heart rate and blood pressure.
