A 1981 report prepared for NASA had already warned of adverse effects from microwave radiation.

Courtney Gilardi’s 10-year-old daughter never had problems sleeping. But in August 2020, the morning after a 5G cell tower was installed within 450 feet of their Pittsfield, Massachusetts, home, she woke up complaining of headaches, dizziness, a buzzing in her head, and general malaise.

Normally, she gets up at 8 a.m. But on that day, she didn’t come downstairs till the afternoon.

“She didn’t look well, and she said that she was headachy, dizzy, fuzzy. Those are not words that she has ever used to describe how she’s been feeling before,” Ms. Gilardi said.

The girl, her sister, and Ms. Gilardi herself, who said she started experiencing sleep disturbances, rapid heart rates, and migraines, were soon diagnosed with microwave syndrome, a condition known to develop after a person is exposed to electromagnetic fields (EMFs) emitted by wireless technologies.
