•   Their website includes an "Automated Online Confidential Diagnostic Self-Assessment" offered anonymously and free of charge. The computer will score this.
•   In addition, since some people are trying light therapy without professional guidance, their  "Ask the Doctor" column is intended to answer questions even most doctors can't answer. You can also ask your own question in this anonymous forum.
•   Although simple in design, home construction of light boxes is discouraged because of the danger of excessive irradiation. Some amateur assemblers have experienced corneal and eyelid burns.

Find out your stress level  The computer will score this and indicate a rough estimate of your current stress level and the likelihood that you will have health problems due to stress in the next 12 to 18 months. Short-term (acute) stress can keep you awake at night and make you feel irritable and edgy. High stress levels over a long period of time (chronic stress) can cause serious health problems such as high blood pressure, and it can weaken your immune system and make it difficult for your body to fight disease.
