Protective clothing from aluminum foil

Protective clothing from aluminum foil: myth or reality?
Protective clothing made of aluminum foil often appears in a popular culture, imagining as an effective shield from external threats, then as an object of ridicule. But how real is its protective function? Let's figure it out.
Protection against electromagnetic radiation:
Many believe that foil clothes are able to protect against electromagnetic radiation, for example, from cell phones or Wi-Fi routers. To some extent, this is true: aluminum foil is indeed a conductor and can partially reflect electromagnetic waves. However, the effectiveness of such protection is very limited. To create a really reliable screen, special weaving and the thickness of the material that ordinary foil does not provide. Homemade foil costumes will rather create the illusion of protection than to provide real. In addition, one should not forget about the potential cracks and leakage of such a costume?, Which reduce its effectiveness to zero.
Protection from heat and cold:
Aluminum foil has low thermal conductivity. This means that she can delay heat or cold for some time, just as thermal insulation in houses does. However, such protection will be very short -term and insufficient for serious temperature fluctuations. Under extreme conditions, the foil can hardly provide reliable protection against overheating or hypothermia. Moreover, the foil does not breathe, which can lead to overheating of the body under it.
Myths and reality:
In conclusion, it is worth noting that clothing made of aluminum foil is not a reliable means of protection against most threats. Its ability to reflect electromagnetic radiation is minimal, and protection against temperature fluctuations is extremely limited and can even be dangerous. Although the foil can be useful for some highly specialized tasks, its use as protective clothing is rather a myth than reality. For this protection, specially designed materials and technologies are required, taking into account the specific type of threat.
