It is customary in clinical practice and elsewhere to put on a mask for protection against infection, dust, and so forth. The veil, which is traditionally worn by women in many Muslim countries, especially in Saudi Arabia, may have a similar effect. The study was carried out during 1998-1999 in the eastern province of Saudi Arabia. Adult women were asked to answer a structured questionnaire related to the occurrence of respiratory tract problems and about veil wearing. Veil wearing was practiced by 58% of the sample. Respiratory infections and asthma were significantly more common in veils users (p < 0.00001 and p < 0.0003, respectively). This unexpected finding was probably secondary to infection. More and bigger studies are recommended.
