Excessive blue light from our gadgets may accelerate the aging process

Too much screen use has been linked to obesity and psychological problems. Now a new study has identified a new problem—a study in fruit flies suggests our basic cellular functions could be impacted by the blue light emitted by these devices.

"Our study suggests that avoidance of excessive blue light exposure may be a good anti-aging strategy," advised Giebultowicz.

The researchers have previously shown that fruit flies exposed to light "turn on" stress protective genes, and that those kept in constant darkness lived longer.

Blue light exposure caused significant differences in the levels of metabolites measured by the researchers in the cells of fly heads. In particular, they found that the levels of the metabolite succinate were increased, but glutamate levels were lowered.

"Succinate is essential for producing the fuel for the function and growth of each cell. High levels of succinate after exposure to blue light can be compared to gas being in the pump but not getting into the car," said Giebultowicz. "Another troubling discovery was that molecules responsible for communication between neurons, such as glutamate, are at the lower level after blue light exposure."

The changes recorded by the researchers suggest that the cells are operating at suboptimal level, and this may cause their premature death, and further, explain their previous findings that blue light accelerates aging.

The signaling chemicals in the cells of flies and humans are the same, so the there is potential for negative effects of blue light on humans," explains Giebultowicz.

"We used a fairly strong blue light on the flies—humans are exposed to less intense light, so cellular damage may be less dramatic. The results from this study suggests that future research involving human cells is needed," concluded Giebultowicz.

it says it’s on google play too- but i didnt’ see it- I’ll check out that video on cortisol- something is messed up-

One more post- won’t keep bugging ya on the issue. But just watned to report that I don’t think the app I’m using is accurate.,had to get up at 3 am, but app showed me “sleeping the whole time” despite about 20 minutes of not even being in room (dang bladder!). Anyways, I also kept waking up last night too. Lay there for about 15 minutes or so, and fall back asleep. The app didn’t catch any of that. (It does record snoring and breathing or not breathing events, in audio shorts though, which is useful).

Gonna try another app tonight, and intentionally get up from bed for a bit to see if it catches it or not.

Mintal does seem to accurately record wake ups.
Every once in a while, It will tell me that tracking got interrupted. Sometimes that happens if I’m up too long or I turn on the TV, or if i roll over onto the phone or the phone runs out of power.

But I can get up and go to the bathroom, leaving the phone in the bedroom and it seem to acurately know that I was awake.

Thanks for the info. I’m gonna try another app tonight. Then try the current one agsin and intentional,y get out of bed to see if it catches it, but last night wasn’t too good at doing so. It was highly rated, 4.8 I think it was, but we Wil. See, kinda doesn’t look like it will record accurately as of now
