Like all living things, humans are bio­luminescent (meaning we glow) – We glow brightest during the afternoon. weirdinteresting & funny facts

what

i’ve been staring at this for like 5 minutes. so.. what. i don’t think people glow. but this is telling me that we actually emit visible light.. especially in the afternoon?? am i reading this right or what

"all living things" plants. when do the plants glow

science side of tumblr pls

I’m not from the science side of tumblr, but here’s the answer anyways:

 Basically, all living things are bioluminescent because every living thing has chemical reactions occurring in their cells. The energy created from these chemical reactions physically manifests as light, thus… all living things naturally glow.

 However, this glow cannot be seen by the human eye. In fact, the only way they’ve ever captured this light is through special cameras. Using these ultra special cameras, they’ve imaged subjects’ bodies over 24 hour periods. It has been found out that humans emit the most of this glow during the afternoon (about 4 PM), it is the weakest in the morning (about 10 AM), and the brightest light is emitted from the cheeks, neck, and forehead.

The light is about a thousand times weaker than what humans can perceive.

 Basically, it’s a side effect of metabolic reactions. It’s been suspected that humans are bioluminescent for years, but they weren’t able to confirm it until recently thanks to technology and a man named Masaki Kobayashi from the Tohoku Institute of Technology.
