The autumnal equinox will occur in just a couple of days, September 22, 2017. Every year around this time i start using my light box to ease my symptoms of seasonal depression. My body tells me that it is time to start. I start sleeping more than normal, craving sweets and needing more coffee to stay alert.
I am one of the lucky ones who gets immediate relief from using a light box. Everybody is different and you really don't know how much benefit you will get until you give it a try.
If you are feeling depressed about the upcoming dark gloomy Seattle weather, maybe your body is telling you that you need more light.
