A study conducted by researchers at Northwestern University in the United States proves that the light from our smartphone, tablet, and computer screens is harmful to the body. These radiations could even promote diabetes or obesity.
Several scientific reports had already mentioned the harmful effects of screens on sleep. With this publication in the scientific journal Plos One, it is our metabolism that is targeted. According to the researchers, too early or too late exposure to artificial light affects weight gain.
To reach these results, two groups of people were exposed to these energy sources at different times of the day. And the result is clear: "the earlier in the day light exposure occurs, the lower the individuals' body mass index".
The main cause of weight gain is "blue light". It is produced by the omnipresent diodes in our smartphone, tablet, and computer screens, because they are small in size but high in luminosity. Problem: they emit a significant amount of "blue light", the most energetic and harmful part of light. According to the study, this light causes insulin resistance and glucose spikes, fat creation, weight gain, and diabetes.
Researchers recommend exposing yourself as much as possible to natural light, for at least 20 to 30 minutes a day, between 8:00 AM and 12:00 PM, gently emerging from darkness in the morning, and compensating for sunset with moderate light.
Don't forget to equip yourself with blue light blocking glasses when you are in front of any screen. These glasses significantly reduce the harmful effects of digital screens and prevent the symptoms mentioned above from appearing. The advantage of current glasses: they can be adapted to your vision.
