A brain shielding radiation cap is provided; electromagnetic waves can realize non-thermal effect on people through the following path: nerve-endocrine-sensory organ-cardiovascular-blood-muscle, wherein the nerve system and endocrine system have most sensitive feelings on an external electromagnetic field; in the nerve system most sensitive to the magnetic field effect, the thalamus portion and cerebral cortex are most prominent; therefore, as long as the brain is shielded, the electromagnetic wave damages on human body can be greatly reduced; the brain shielding radiation cap is simple in making, low in cost, and can provide important influences on people life; it is believed that in the near future, the brain shielding radiation cap will become an essential part of daily life like a watch.
