Every claim in the Short, and the sentence behind it
Your body glows, but you can’t see it.
“We found that the human body directly and rhythmically emits light.” … “The intensity of the light emitted by the body is 1000 times lower than the sensitivity of our naked eyes.”
Abstract
Scientists in Japan captured it in complete darkness, with a camera cooled to −120 °C.
“A cooled CCD camera operated at −120°C with slow scanning mode read-out was used” … “The camera was placed in a light-tight room in complete darkness”

The light comes from chemical reactions in your cells.
“Ultraweak photon emission is known as the energy released as light through the changes in energy metabolism.” … “…whose excited states emit biophotons”
Abstract · Discussion
It’s weak in the morning and peaks around 4 p.m.
“Photon emission was weak in the morning, increased in the afternoon and peaked in the late afternoon (ca 16:00)”
Results
Your face is the brightest part.
“In all images, photon emission intensity from the face was higher than from the body.”

What the study doesn’t say
It measured five healthy male volunteers. The paper generalises in its own abstract (“The human body literally glimmers”), but the sample is small.
This is chemistry, not an “aura” or an “energy field.” The light is a by-product of metabolism, and nobody can see it without a specialised camera in total darkness.

The Short
37 seconds. Every number on screen comes from the paper: 1000×, −120 °C, about 16:00.
The “eye threshold” bar in the Short is symbolic. Drawn to a true 1000:1 scale it would be one pixel tall.
