A reader asks:

 I recently took your very interesting and informative on-line questionnaires. The feedback was that I probably have a mild to moderate depression with strong seasonal tendencies. Any suggestions how to approach working with this?


As far as we know, the optimum light treatment regimen for subsyndromal seasonal affective disorder (SAD), or winter doldrums, is no different from that for full-blown SAD. In other words, milder winter depression does not imply that you need less light than for major depression. Therefore, for starters, we would suggest that you follow the 30-minute, 10,000 lux regimen described on our website.
