In maintaining communication devices, why is it essential to keep antennas at a specific distance from the skin?

Keeping antennas at a specific distance from the skin is crucial primarily to prevent skin irritation. When antennas are placed too close to the skin, the emitted electromagnetic fields can cause discomfort or irritation to the skin tissue. The close proximity can lead to overheating or localized heating effects, especially with devices that operate at higher frequencies or power levels.

Ensuring the proper distance helps mitigate these risks, promoting user comfort and safety while using communication devices. Although other factors such as signal strength, noise interference, and safe operation are important considerations, the primary concern under this context directly relates to skin health and comfort.
