Face masks originated in Egypt. They were worn to protect the skin from the harmful effects of the sun. In addition to the sun's harmful rays, the Egyptian people were also woken in the morning with the pain of their skin. Thus, face masks have been an important part of health and beauty traditions for centuries.
A face mask is generally a sheet or a cloth mask worn over either the nose and mouth, or over one eye, used to prevent particles, bacteria, and allergens from entering the respiratory system. Face shields can be made from many different materials, including plastic composites, vinyl composites, fabrics, surgical masks, and surgical respirators. These materials work by creating a barrier between the face and the particles that may cause health problems. While face masks prevent particles, germs, and allergens from entering the respiratory system, medical respirators are designed to filter particulates from the air.
Although most people are familiar with disposable plastic pieces called face masks, these are just one type of face mask that has many uses. Traditional face masks made from plastic composites have been found to contain amounts of cadmium, chromium, lead, copper, mercury, and other toxic elements. However, a new type of face mask called a non-disposable mask, contains no hazardous elements but instead uses a synthetic mesh to prevent particles, viruses, bacteria, and allergens from entering the respiratory system. Non-disposable face masks have recently been found to be effective in containing large quantities of bacteria and allergens.
The current global pandemic is a reminder of how easily a new disease can spread and disrupt our daily life. A recent study found that a relatively new strain of a flu virus was responsible for the sudden surge of excess illness among several US children. Although the virus has not yet reached epidemic proportions, the alarming news serves as a timely reminder that the risk of contracting a deadly virus like this is always present. Therefore, it is essential to protect ourselves by wearing face masks when outside and to observe proper personal hygiene.
Face masks have traditionally been used to prevent the spread of airborne diseases, particularly the serious flu virus. However, studies have shown that there is also a correlation between wearing face masks and increased risk of bacterial and fungal infections when not wearing masks. In addition to protecting our lungs from pollutants and allergens, the new study also found that the bacteria and fungi grew more quickly in areas where there were higher levels of social distancing. Social distancing refers to a situation in which individuals tend to spend more time alone, such as at work or at home.
Currently, researchers are focusing on how to prevent the transmission of virus-like infectious agents like the swine flu in schools. The findings of this study will be helpful in the development of educational campaigns geared towards reducing social distancing and boosting school immunization rates. In addition, face masks may prove to be effective in the prevention of other diseases, including colds, the flu, and respiratory illnesses like the common cold.
