You may have heard that there are possible health effects that come from Wi-Fi and other electromagnetic frequencies. My grandpa is convinced that the Wi-Fi signal in the house is giving him a headache. He’s not alone. This claim sparks controversy in scientific and public communities alike.
A Look at Wi-Fi and Radio Frequencies
Wi-Fi utilizes radio waves. Specifically, it’s a form of electromagnetic radiation with frequencies around 2.5 GHz and 5 GHz. These frequencies are much lower than X-rays, UV light, or ionizing radiation – all of which have the capability of damaging human tissue.
Wi-Fi is non-ionizing, so it’s considered safe. However, the question remains about whether it is capable of inducing biological effects, such as headaches.

Is Electromagnetic Hypersensitivity a Thing?
Electromagnetic hypersensitivity (EHS) is a real condition. A person may experience headaches, dizziness, and fatigue if they’re in close range of electromagnetic fields, which includes Wi-Fi.
People who suffer from EHS self-identify. Science has yet to establish a true physiological cause. As such, some believe that EHF is either psychological (and potentially even the placebo effect) as well as environmental factors.
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 current evidence.
So, is grandpa lying? No. However, it’s possible that it may not be just from the Wi-Fi since there isn’t enough science to say that the exposure is harmful. There’s still a lot of research being done. In the meantime, if you do believe your Wi-Fi is giving you a headache, distance yourself from the Wi-Fi router and reduce your screen time.
