First of all, the difference between artificial and natural light is vast. A recent Swiss study showed that people exposed to predominantly artificial light throughout the day were less alert in the evening than those exposed to natural sunlight. Just as striking, a 10 degree drop in temperature from 77 degrees Fahrenheit produced 44% more mistakes by employees in a Cornell study.
If you want to boost productivity with temperature and lighting alone, there are a few things you can do. Make sure you wake up about the time the sun rises (or before if possible). This will help normalize your cortisol levels considerably. Next, use a portable heater to keep your workspace at an optimal 77 degrees.
