You will never want to turn on the light again if you know this truth

Many people have a habit of turning on night lights dimly when sleeping because of fear of darkness or to feel better. But according to the latest research, dim light can affect our decisions.

Many people have a habit of sleeping under dim yellow lights or couples who want to have a romantic space so light candles flickering or turning on light to create romantic and romantic feelings.

Even in some cafes, the psychology of customers is that couples who love each other only use low light to create an emotional atmosphere.

However, according to a new study, dim light may cause you to have cognitive impairment , which can lead to poor decisions.

Blurred light can cause you to lose consciousness.

University of Michigan researchers did an experiment to test the cognitive ability of white mice. He sleeps at night and wakes up in the morning - just like a human. But the difference is that one lives in dim light and one lives under normal light conditions for 4 weeks. So what is the result?

The mouse must live in the dim light, which weakens the usual "exercises" such as running circles, playing the slide, . Especially the ability to recognize their space is significantly reduced, often being hit on the wall. glass.

Besides, scientists have found that, for mice living in dim light conditions, its hippocampus area has shrunk by 30%. This is an important area of ​​the anterior brain, located inside the temporal lobe, which serves to store knowledge and form new memories. At the same time, this mouse also appeared to reduce a type of peptide in the brain. This peptide is a neurotrophic element derived from the brain, which binds neurons in the hippocampus.

Joel Soler, a psychology graduate student explains: 'Because of the lack of connections between neurons in the hippocampus area, the brain reduces learning ability and memory is no longer stored. half. In other words, low light makes our subconscious weak. '

Meanwhile, the other mouse living in normal light has different results. He not only worked better physically, obeyed better orders, but also determined very precise directions.

Should turn off the lights when sleeping will make you sleep well and ensure better health.

In addition, the mouse is subjected to dim light, after being able to live in normal light for the next 4 weeks, all brain and cognitive abilities have returned to normal, memory is enhanced.

This is the first time a study has shown that changes in the light environment can affect structural changes in the brain.

The co-author of this study, Antonio Nunez, professor of psychology, said: 'Like mice that are difficult to determine the direction after a period of time in dim light, it is difficult to find the location the car is parked after a busy day in a shopping mall or movie theater - where the light is extremely weak or even after getting up under dim lights'.

Perhaps people should rethink the use of faint nightlight in the room, instead turn off all lights when sleeping will make you sleep well and ensure health.
