Screen ageing horror: Too much blue light from gadgets could add years to your life

Dr Giebultowicz said: “To understand why high-energy blue light is responsible for accelerating ageing in fruit flies, we compared the levels of metabolites in flies exposed to blue light for two weeks to those kept in complete darkness.”

The team found that exposure to blue light changed the levels of metabolites measured in the cells of the fruit flies’ heads.

Specifically, they found that the levels of succinate were increased, but glutamate levels were lowered.

As Dr Giebultowicz noted, “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.

“Another troubling discovery was that molecules responsible for communication between neurons, such as glutamate, are at a lower level after blue light exposure.”
