Sitting for too long under an electric light will make you age quickly

Using electric lights in a blameless manner can have a bad effect on yourself.

In 1989, American scientist Thomas Edison succeeded in bringing electric light bulbs into service for human life. It can be said that Edison opened an era where people can completely repel darkness according to their will.

The light bulb was born, marking a completely different era of humanity, where darkness was repelled

For one thing, this era turned out to be more harmful than we thought, because according to a recent study, artificial light is not good for our health. Muscles weaken, bones are thinner , that's what experts from the Leiden University Medical Center (Netherlands) concluded.

Experts have done experiments on mice. They kept the mice illuminated continuously for 6 months. The results showed that the muscles of the poor mice were atrophied, showing signs of osteoporosis, while the immune system was severely reduced.

Electric lights turned out to be more harmful than we thought

Come here, many people will think that if it is illuminating continuously, what is the normal use? But the problem is that experts also think that our current electric light cycle is too much, and it will affect health.

Professor Johanna Meijer from the University of Leiden, who led the study, said: " We used to think that light and darkness are not harmful, at least to health. But this is not true, based on data from a lot of laboratories around the world, that is, too much intervention in the day-night cycle can seriously affect health ".

However, the good news is that the data also shows that the rats recovered after returning to natural light. According to Professor Meijer: " Negative effects on health will be reversed if it returns to the natural day-night cycle ".

This means that we should carefully consider our sleeping habits. In fact, even during the day, we spend a lot of time interacting with artificial lighting: in classrooms, working rooms .

At night, it is not necessary to say, 75% of the world population is " night owl ", with the habit of being very late to work. And of course, the length of exposure to artificial lights is too long that will definitely affect our health.

More dangerous, the artificial light we contact may come from electronic devices such as smartphones, tablets . It is blue light , simulating sunlight, which can cause sleep disruption. . Even research has shown that blue light also causes vision loss, or cataracts - one of the most common causes of blindness in the world.

Using your phone at night can be dangerous for yourself

In short, the purpose of the study is to allow us to balance the time of exposure to artificial lights every day.

You can choose bright sitting angles to take advantage of the sun during the day. At night, try to finish the job as soon as possible, because the longer you sit, the more you will see health decline.

The study is published in Current Biology.
