Three children and their parents rapidly came down with multiple health problems — including sleep difficulties, headaches, stomach pain and skin rashes — when they stayed at a summer home 125 meters away from a cell tower with multiple 5G antennas, according to a new peer-reviewed case study.

The study, published Dec. 2 in the Annals of Clinical and Medical Case Reports, reported the family members’ symptoms subsided swiftly after they returned three days later to their regular home where they were exposed to much lower levels of 5G radiofrequency (RF) radiation.

The children — ages 4, 6 and 8 — also experienced emotional symptoms, such as heightened irritability, while staying at the summer home close to the 5G tower.
