" The chowdry, or burqa -- the Saudi, North African, and Central Asian version of the head, face, and body shroud -- is a sensory deprivation isolation chamber. It is claustrophobic, may lead to anxiety and depression, and reinforces a woman's already low self-esteem. It may also lead to vitamin D deficiency diseases such as osteoporosis and heart disease. Sensory deprivation officially constitutes torture and is practiced as such in the world's prisons. "
