YOUR AMAZING BODY

THE human body has its own glow, emitting light in extremely small quantities.

According to researchers in Japan, the glow is 1,000 times weaker than what the human eye can perceive.

It also varies, with the lowest levels at 10am and the highest at 4pm, according to a paper in medical journal PLOS One.

Scientists in Japan used ultrasensitive cameras to monitor five men who were placed bare-chested in front of the cameras in darkness for 20 minutes, every three hours from 10am to 10pm for three days. Scientists believe the light is caused by the metabolic process, chemical reactions that occur as the body turns food into energy. Faces glowed the most.

Bioluminescence, a similar process, occurs in animals.
