Aluminum foil mask

Mask from aluminum foil: myth or reality?
Recently, information about aluminum foil masks that allegedly protect against various influences has been emerging on the Internet. Let's figure out how justified these statements are and whether it is worth using such an unusual way to protect.
Protection against electromagnetic radiation:
Many believe that foil is capable of blocking electromagnetic radiation from mobile phones, Wi-Fi routers and other electronic devices. Indeed, aluminum foil is an electricity conductor and can reflect part of the electromagnetic waves. However, in order to achieve significant protection, the foil layer should be thick enough and perfectly smooth. A homemade food foil mask is unlikely to provide reliable protection against radiation, and its effectiveness will be extremely low. Moreover, such a mask is inconvenient to use and can cause discomfort.
Protection against viruses and bacteria:
The idea to use foil as a means of protection against viruses and bacteria is absolutely insolvent. The pores in the foil are too large to delay viruses and bacteria. Moreover, foil cannot be disinfected in standard ways. Its use as a means of protection against infections is not only useless, but also potentially dangerous, as it creates a false sense of safety. To protect against viruses and bacteria, medical masks that meet the standards should be used.
Harm to health:
Despite the fact that food foil is considered safe for contact with food, prolonged and constant use of a mask from it can be fraught with unpleasant consequences. The foil can cause skin irritation, especially with prolonged wearing. In addition, inhalation of foil particles is also undesirable. Do not forget that the effectiveness of such a mask is extremely doubtful, and potential harm can be significant.
In conclusion, the use of an aluminum foil mask is a rather interesting experiment than an effective way to protect against something. For real protection against various factors, proven and safe methods should be used.
