You may have heard about the possible health effects from Wi-Fi and other electromagnetic frequencies. My grandfather is convinced that the Wi-Fi signal in the house gives him headaches. He is not alone. This statement is controversial in both scientific and public communities.
A Look at Wi-Fi and Radio Frequencies
Wi-Fi uses radio waves. Specifically, it is a form of electromagnetic radiation with frequencies around 2.5 GHz and 5 GHz. These frequencies are much lower than X-rays, ultraviolet radiation or ionizing radiation, which can damage human tissue.
Wi-Fi does not ionize, so it is considered safe. However, the question remains whether it is capable of causing biological effects such as headaches.

Does electromagnetic hypersensitivity exist?
Electromagnetic hypersensitivity (EMS) is a real condition. A person may experience headaches, dizziness and fatigue if they are in close proximity to electromagnetic fields, including Wi-Fi.
People suffering from EHS identify themselves. Science has yet to establish the true physiological cause. Thus, some believe that EHF is either psychological (and perhaps even a placebo effect) or an environmental factor.
Final Thoughts
Most organizations, including the WHO and the International Commission on Non-Iodizing Radiation Protection (ICNIRP), believe that Wi-Fi is safe based on all available evidence.
So grandpa is lying? No. However, it is possible that this is not solely due to Wi-Fi, as there is not enough scientific evidence to say that exposure is harmful. There is still a lot of research to be done. In the meantime, if you think Wi-Fi is giving you headaches, step away from your Wi-Fi router and reduce your screen time.
