These texts attribute the common cold to wind elements entering the body and causing the typical symptoms of sneezing and a Runny nose. In the traditional Islamic medical texts of Al-Jawziyya, we can find numerous references to the "four elements" of fire, water, air and earth and how these affect the body in adverse ways. In particular, we are advised to stay away from drafts and protect our heads in wind, breezes, drafts and cold weather.
All outdoor workers should wear some sort of head covering:
For this reason, protecting the head is even more important in warm weather. V.G. Rocine, a prominent brain research specialist, has found that brain Phosphorus melts at 108 degrees; a temperature that can be easily reached if one stays under the hot sun for any length of time without a head covering. When this happens, irreversible brain damage, memory loss and loss of some brain functions can result. Although this example is extreme, Brain damage can still be measured in small degrees from frequent exposure to and overheating of the head. Bernard Jensen, a naturopath and chiropractor states that this is because the brain runs on the mineral phosphorus, which is very affected by heat.
All public should wear a veil or head-covering workers serving society to ensure cleanliness and purity. Workers in a number of professions wear "veils" - nurses, fast food workers, and deli Counter workers, restaurant workers and servers, doctors, health care providers and many more. In fact, when we compare the number of workers who cover their heads to the number who do not, we find that more people probably cover their heads than do not.
Female Psychological Balance:
Covering the hair can also have a beneficial effect on the female psyche as well. Studies of women being interviewed for jobs show that there is a high correlation between what they wear and their perceptions of how successful they will be in their interviews. There are many more examples of how what we wear can influence how we act.
Wearing a veil can serve to remind women of their religious duties and behavioral expectations. It can also serve as a reminder to women that we are not only individuals, but also representatives and diplomats of our "Ummah."
