Wi-Fi waves, used to transmit the internet to various mobile devices such as cell phones or laptops, pose no health risk, even during childhood or pregnancy.
This happens because the type of waves used is of very low intensity, being up to 100 thousand times weaker than the waves of a microwave, that also do not harm the health. In addition, most routers are more than one meter away from the user, reducing the original strength by more than half.
Thus, according to the WHO, the normal use of wi-fi waves is not capable of causing any type of alteration in the DNA of the cells and, therefore, also does not lead to the development of mutations that can cause cancer in adults or problems of development in children.
Types of radiation that harm health
Electromagnetic waves capable of altering cells and impairing health are those that have a wavelength shorter than visible light, which includes the radiation of the sun, known as UV waves and x-rays, for example. Normally prolonged and unprotected exposure to this type of radiation can lead to cancer.
However, all other types of radiation that have a longer wavelength, such as infrared, microwave or radio waves, can not change the cells and therefore are safe for health.
Within this range, the wi-fi waves have a wavelength greater than the lightning waves, which makes them even safer than all the others.

How to protect yourself from wi-fi waves
If the wi-fi is not harmful to health, there are some people who have sensitivity to all types of electromagnetic waves, developing symptoms such as nausea, excessive tiredness, headache or blurred vision.
In these cases, in order to reduce exposure to wi-fi radiation, one must:
- Stand more than one meter from the router, so that the signal strength reduces to less than half;
- Avoid using laptops connected to the wi-fi, especially the notebook;
- Use the notebook on a desk to increase distance with your body.
However, in situations where the wi-fi does not cause any symptoms these care are not necessary, especially because the use of the cell phone for 20 minutes in call mode transmits more radiation than 1 year of wi-fi usage and even then, poses no risk to health.
