Physiological, biochemical and various all-round beneficial effects
have been reported by a number of studies in normal subjects
practising TM as follows:
Oxygen consumption and metabolic rate
Oxygen consumption reduced to the extent of 16–25% by regular
practice of TM for 40–60 min. Also the reduction in the metabolic rate
achieved after TM was found to be even more than that during the
state of deep sleep .
Reduction in heart rate
Reduction in heart rate by 5 beats/min (from 71 to 66) was reported
during TM and it remained at that level up to 15 min after TM.
Perceptual motor performance
The speed and accuracy in performing complex perceptual motor tes
improved in subjects practising TM.
Level of plasma cortisol and plasma prolactin
Level of plasma cortisol reduced by 25–30% and plasma prolactin
level was found to be increased in subjects practising TM . Blood lactate level dropped from 10 to 6 mg/100 mL (Wallace and Benson, 1972), all indicating a profound state of muscular relaxation. Besides these, other benefits in normal subjects are as follows:
- 1.Reversal of biological ageing as proved by the measurement of
auditory threshold, near point vision and systolic blood pressure
- 2.Improved athletic performance with reduction of heart rate
- 3.Feeling of restful alertness
- 4.Improved memory, intelligence, academic performance and
