Aluminum foil protection

Aluminum foil protection
Aluminum foil is the usual material in the kitchen used to store products and baking. But its protective properties spread far beyond the borders of cooking. Many are interested in whether she can really protect against anything other than light and moisture? Let's figure it out.
Screening of electromagnetic fields:
The foil, thanks to its properties, is really capable of filming electromagnetic fields. Aluminum is a good conductor of electricity, and therefore it reflects electromagnetic waves. This means that by wrapping, for example, a mobile phone with foil, you will reduce the effect of its radiation on you. However, the degree of protection will be incomplete and depends on the thickness of the foil and the frequency of radiation. It is impossible to completely protect against electromagnetic fields with foil. In addition, the wrap process itself can be impractical and disrupt the functionality of the device.
Protection against radio frequencies:
Similarly, the action on electromagnetic fields, the foil can weaken the effects of radio frequencies. This can be useful in situations where it is necessary to reduce the level of Wi-Fi signal or other wireless networks. However, again, this is not a complete protection. The signal can be weakened, but not completely blocked. Moreover, the use of foil for such purposes can lead to interference in the operation of electronic devices.
Myths and reality:
It is important to understand that protection using aluminum foil is not a panacea. Myths are common that foil protects against radiation of various household appliances, from listening and even from negative energy. There is no scientific confirmation of these statements. The foil can provide some shielding of electromagnetic waves, but its effectiveness is limited and depends on many factors. Before using foil to protect against any radiation, it is better to contact specialists to assess the situation and choose suitable methods. In most cases, more effective and safe protection methods exist.
