A human body emits more radiation in the gigahertz range than a cellphone?
- ko27 9y agoI am talking about the infrared range, which is above 300GHz.
- cma 9y agoThe body also reflects terahertz radiation from the surrounding environment, even directly into other people's eyes. This has the bizarre side-effect of causing people to be able to "see" each other.
- slackingoff2017 9y agoThis is great
- katastic 9y agoWon't someone think of the children!?!?
- manmal 9y agoInteresting thought. Near infrared light does interact with cells (photobiomodulation), usually in a beneficial way. Maybe the wave form is another factor, or some frequency ranges are beneficial while others are not?
- hutzlibu 9y ago"some frequency ranges are beneficial while others are not" Certainly. Heat is nice (if not too much), but x-ray is usually bad. Gamma-rays a lot worse. And cellphone radiation is probably somewhere in between ... so like the article cites: we don't know yet. So I do not like sleeping next to my mobile nor have it next to lower body parts for too long ...
- thaumasiotes 9y agoHeat is not a frequency or a frequency range.
- BenjiWiebe 9y agoGenerally speaking, warm/hot objects radiate in the infrared range. In my understanding, all objects radiate something, unless at absolute zero.

- pmontra 9y agoIt's quite complicated. Interesting read: https://en.wikipedia.org/wiki/Heat https://en.wikipedia.org/wiki/Heat
- CyberDildonics 9y agoI don't think the radiation heat transfer from microscopic bodies is the same as saying a human body emits infrared light on a macro scale.
- boooooo 9y agoIt does though, that's how infrared cameras work for one thing.
- CyberDildonics 9y agoI think this is mixing up two different things. People seem to emit infrared light, but that is not the light that people usually see through an infrared camera. https://www.livescience.com/7799-strange-humans-glow-visible-light.html https://www.livescience.com/7799-strange-humans-glow-visible... This is showing infrared and even visible light radiation from a person's body in extremely small amounts. An infrared camera just sees infrared light period, the vast majority of which is what is reflecting off of someone from other sources.
