Why do doctors recommend using the SADelite, TRAVelite, BOXelite, and Flamingo in the early morning and only for 15-30 minutes?
The first clinical studies done in the early 80’s observed that 2500-5000 lux light boxes required treatment times of 2 to 4 hours. More recent studies have shown superior treatment for SAD symptoms using 10000 lux devices for only 30 minutes. Early morning treatment was also shown preferable to other times of the day because it did not interfere as much with the sleep-wake cycle.
