Reducing the room temperature to 68 degrees Fahrenheit or colder resulted in employees making 44 percent more errors. The optimal room temperature was 77 degrees Fahrenheit. The study stated that when a person is cold, energy is diverted to keep warm and takes away from the ability to concentrate. The study also noted that being warmer also made people happier.


The best light source for work is sunlight or candlelight.  Flourescent light, common in schools, is the most disruptive to a readers eyes and visual process. It can effect physiological systems and eye-brain processing.   

If you don't have access to sunlight try reducing shiny surfaces and glare.

Possible side effects of flourescent lighting:

Eye pain

Blurred vision

Difficulty reading or focusing

Shortness of breath





Feelings of depression

Disrupted sleep


If the study area is difficult to heat without making the entire house too warm, you can use a blanket or small room heater during study times. Have a thermometer nearby to keep track of the temperature.


Comfort is invaluable when learning new skills. Select the correct table and chair height. When uncomfortable it's difficult to pay attention and concentrate.  A correct chair height allows the feet to be flat on the floor with the knees bent at a 90 degree angle.  Dangling feet do not allow for a proper position which interferes with the eye brain process.

Proper posture allows for:

Good Circulation

Improved Alertness

Increased concentration

More comfort


Our bodies are comprised of 60 percent water. Water is a conductor of all of the electrical impulses that occur within our bodies. There are millions of impulses occurring each second in our eye-brain process. When a student becomes dehydrated, the eye- brain process will not be optimal. It has been shown that hydrated children have better memories. Headaches, fatigue, and lightheadedness are early signs of dehydration.
