3.Get Better Lightening

laboratory study out of Michigan State University determined that working in an environment with dim lighting can "change the brain's structure and hurt one's ability to remember and learn."

• Half of a group of Nile grass rats were kept in an environment with dim lighting. 
• The other half of the group of rats lived in an environment with much brighter lighting.

In the end, the rats in the dim light "lost about 30 percent of capacity in the hippocampus, a critical brain region for learning and memory, and performed poorly on a spatial task they had trained on previously," according to the study.
