In humans, MM-waves have penetrating effects including impacts on the brain, producing EEG changes and other neurological/neuropsychiatric changes, increases in apparent electromagnetic hypersensitivity and produce changes on ulcers and cardiac activity.

Can millimeter waves penetrate skin?
Millimeter waves penetrate into the human skin deep enough (delta = 0.65 mm at 42 GHz) to affect most skin structures located in the epidermis and dermis.
Is mmWave safe?
Unlike much higher frequency ultraviolet, X-ray, and gamma radiation, mmWave radiation is non-ionizing. Thus, the main safety concern is heating of the eyes and skin caused by the absorption of mmWave energy in the human body. Fortunately, our bodies are reflective and do not absorb much mmWave radiation1 2.
What are the disadvantages of millimeter wave?
Disadvantages of Millimeter Wave
Higher costs in manufacturing of greater precision hardware due to components with smaller size. It may result in lower sensitivity in a receiving system due to the lesser energy collected by the smaller size antenna. At extremely high frequencies, there is significant attenuation.
Is 60 gigahertz harmful to humans?
In that study, we detected no obvious adverse effects of 60-GHz exposure. However several other studies reported some non-thermal effects on biological organization [3–6]. In 2013, the International Agency for Research on Cancer (IARC) classified radiofrequency into Group 2B, 'possibly carcinogenic to humans' [7].
