Some people report similar symptoms when they work inside under fluorescent lights and dont get outside in the sun during the day enough. Without the daylight spectrum certain body functions may not be instigated or supported properly and the body responds in a negative way.
Solutions
- Use a broader spectrum fluorescent bulb. A daylight or full spectrum bulb uses a combination of gases to increase the light spectrum emitted.
- Take a break and get outside for a few minutes.
