Why do i feel a strange sensation in my head when using 5ghz wifi?

Is it weird i cab tell when my laptop switches over to 5ghz from 2.4ghz wifi? I get a strange feeling in the front of my head when using 5ghz wifi from things like my laptop or desktop computer. I have read that other people experience this and i have talked to one other person who could also feel a strange sensation when using 5ghz. What causes this? Is it a potential health risk? Has there been a lot of research on health risks for 5ghz wifi?
