Some doctors are reporting a new health condition described as “Wi-Fi sensitivity.” But many physicians suggest it is not a physical ailment, but a psychological condition.

David Carpenter, M.D., tells CBS news a scientific link between Wi-Fi and health is clearly emerging.

“There is a body of evidence that is strong. It’s not 100 percent understood, but it’s strong evidence that this is a real syndrome that causes real harm to real people,” he said, suggested it may affect 5 percent of the population.

“They walk around feeling ill and they don’t know what to do about it.”

But other doctors counter that the evidence connecting Wi-Fi to illness just isn’t there.

“It’s a psychological phenomenon,” said neuropsychologist William Barr, M.D.

He said some people may have symptoms, but what causes them is the power of suggestion may play a role.

“They essentially establish a belief that something has the potential to cause a symptom, and then when they come in contact with the cause they develop those symptoms,” he explained.
