We all know that it is not good to use mobile phones for a long time. But a new study suggests that long-term use of mobile phones may also make us age faster.

In order to understand the effects of blue light on mobile phones on humans, researchers at Oregon State University in the United States conducted experiments on fruit flies. They found that the blue light emitted by smartphones and other electronic devices interferes with the basic functions of cells.

"televisions, laptops, cell phones and other electronic devices emit blue light, and excessive exposure to blue light is harmful to skin cells, fat cells, nerve cells and many other cells," said Jadwiga Giebultowicz, a scientist at Oregon State University. "our research shows for the first time that blue light can change the levels of some metabolites in fruit flies. Without these substances, cells are unable to perform specific functions properly. This finding suggests that avoiding excessive exposure to blue light may be a good anti-aging tool. "

Blue light activates genes related to stress protection in fruit flies, and fruit flies exposed to darkness for a long time live longer. "to understand why intense blue light accelerates the aging of fruit flies, we compared the metabolite levels of fruit flies exposed to blue light for two weeks and those that were completely dark," Gibtowitz said. "

Metabolites generally refer to small molecular substances obtained by all organisms by decomposing drugs or food.

The researchers found that blue light exposure significantly changed the metabolites in the fruit fly's head: when exposed to blue light, succinate levels increased and glutamate levels decreased.

"Succinate is very important to the function of the cell, and it participates in a biochemical reaction that provides the energy needed for the cell's activity. the elevated level of succinate suggests that the molecule is not involved in the reaction in time, which can cause cells not to get enough energy, just as gasoline cannot get into the engine and can only be accumulated in the fuel tank." Gibbs Towitz said.

In addition, blue light irradiation also reduces the substances responsible for transmitting neural signals, such as glutamate, which has an even more serious negative impact on cells and individuals. This is probably because blue light exposure causes cell activity to be not at its best, and some cells even die prematurely. As a result, too much blue light accelerates aging.

The study from Oregon State University reveals the possible effects of blue light on people, but the subjects are not real humans. Next, scientists plan to use human cells for further research.

A survey on the use of electronic screens in April 2022, researchers at the University of Leeds in the UK surveyed 500 British adults about their daily use of electronic screens.

Respondents to 1ax 4 spent more than 14 hours a day looking at the screen.

Due to the impact of the epidemic, the respondents of 1Compact 2 spent more time on the screen every day than before.

Four out of every 10 respondents felt physical discomfort, including visual fatigue, headaches and general weakness.
