“Not all effects of the practice of meditation are beneficial. Shapiro (1992) found that 62.9% of the subjects reported adverse effects during and after meditation and 7.4% experienced profoundly adverse effects. The length of practice (from 16 to 105 months) did not make any difference to the quality and frequency of adverse effects. These adverse effects were relaxation-induced anxiety and panic; paradoxical increases in tension; less motivation in life; boredom; pain; impaired reality testing; confusion and disorientation; feeling 'spaced out'; depression; increased negativity; being more judgmental; and, ironically, feeling addicted to meditation.” Dans Perez-De-Albeniz, Alberto & Holmes, Jeremy.
