In the global debate regarding the dress codes for Muslim women, one important factor is often overlooked: The fact that depriving a human being from live-giving sunlight and air represents physical torture. Indeed, this form of torture has been used for centuries in prisons."Osteomalacia. This disease--its name literally means bad bones--results primarily from a severe vitamin-D deficiency. Arabian and Indian women who keep themselves heavily veiled frequently develop such painful backs that they can scarcely rise; and they suffer multiple spontaneous fractures and have extremely rarefied bones, all of which clears up dramatically when vitamin D is given them." (Davis, Let's Get Well, p. 256.)
"Sir Robert McCarrison, the great English physician, wrote of osteomalacia in India among the Mohammedan women observing the custom of purdah. These women veil their faces at adolescence and rarely go outside their homes."
"...in most of the Sunni Muslim women (who form majority of the Muslims), in spite of high intake of calcium, osteomalacia is often seen. There are two reasons for this:
"1. Use of burkha which prevents sunlight reaching the skin."2. Living indoors - most of the Muslim women specially those staying in the Muslim localities, do not move out of the house and thus are not exposed to the sun and often develop osteomalacia."

In addition to developing bone and other problems from a lack of vitamin D and melatonin, covered women are deprived of fresh air on their skin, which is the body's largest organ. Hence, the skin is not given the opportunity to breathe adequately. Furthermore, the color of choice in covering up women because of "religious" purposes is often black and sometimes blue, undoubtedly creating much sweltering and heat stroke in the very hot regions in which this clothing is traditionally worn.* There are many forms of oppressive dress for women within the Islamic world, compelling us to learn these terms:
burqa/burkha/burka
niqab
chador
sitar
hijab
abaya
jilbab
So obsessive is this women-oppression that there are reputedly over 100 terms for bagging females.
Women in hijabs 'need sunlight or risk illness'
