A safety helmet lining emitting far-infrared radiation is mounted inside a safety helmet and has an active layer and ceramic powder. The active layer is mounted inside a safety helmet. The ceramic powder is installed on the active layer and is made of material that is capable of inherently radiating far-infrared rays that can penetrate deeply into a human body and resonate with cells to activate cells and accelerate metabolism. Further, far-infrared rays also have proven utilities of deodorization and bacteriostasis. So, activity of bacteria propagating in the lining of a safety helmet can be effectively inhibited and bad smell emitted from people's heads after wearing the safety helmet often can be effectively mitigated by the far-infrared rays radiating from the ceramic powder.
