Discover cells that transmit the effect of the blue light of the phone to the brain
CALIFORNIA: Scientists in a medical study have identified cells in the eye that work to reset the body’s clock system by determining ambient light when exposed to artificial light at night. If so, our internal clock becomes confused, which can result in various medical problems.
The cells identified in this study by the Salk Institute for Biological Studies in the US state of California have been identified as the most sensitive to blue light, the effect of which reaches the brain and affects the body’s biological clock. Occurs and increases the risk of insomnia, this light is commonly used in LED lights and other devices such as smartphones and laptops.
It has been proven that bright light at night (light emitted from smartphones, laptops, etc.) affects the body’s biological clock and increases the risk of insomnia. This body clock plays an important role in health. And day and night cycles affect the risk of various diseases such as cancer, heart disease, obesity and type 2 diabetes.
The stress of using a mobile phone at night increases the release of the stress hormone cortisol in the brain, which increases the electrical activity in the brain and does not relax the skin, which is why in the past it The suggestion is to stop using the screen one or two hours before bedtime.
Scientists say that even in blind people, their biological clock is aware of the cycle of day and night, due to which even the blind can sense light. Research shows that this is called IPRGCS. Cells send light signals to the brain, and even blind people use them to determine day or night.
Researchers say that TVs, computer monitors and smartphone screens can be designed to prevent blue light from affecting the brain.
