'Brain of goldfish' because the office does not have enough light

Saving electricity is a good thing to do but don't let the light in the office so weak that employees work in a state of forgetfulness and poor learning.

In the study of Michigan State University (USA), only 4 weeks of exposure to poor light conditions were sufficient to alter some structures in the brains of the Nile rats.

The office lacks a few lamps that can reduce work efficiency because employees will often forget and learn poorly.

The reason for the experiment was carried out on mice by behavioral mice, the dependence of the biological clock on human-like light.

These structural changes have a strong impact on their ability to remember and learn, in particular by reducing up to 30% of the brain region's capacity. In other words, only 4 weeks live in dim light that makes them " , or forget it or not, the ability to absorb a new problem or skill also goes down.

Professor Tony Nunez, one of the authors, further explained that dim light also reduces brain-based neurotrophic factors , a substance that maintains the connection of healthy neurons in the region. hippocampus.

The survey steps in the US also show that people who often have to work in the dimest light are. According to scientists, 30% of memory and learning performance is a large enough number for employers to rethink the arrangement of additional lights in reasonable locations, if they want employees to work effectively. than.
