Seasonal affective disorder has little effect on some, but it hits others hard. Some swear that light therapy is the solution. Use a bright light for minutes a day to banish the winter blues? Great!
The theory is that very bright light will affect melatonin, a light-sensitive hormone. Does it really work, or is it a placebo? A better question? Who cares?
If it’s been used to treat SAD since 1984, there must be something to it. If you experience SAD, give it a try. There are very few side effects, and it may be the solution for you!
