Treatment for seasonal affective disorder

 Seasonal affective disorder (SAD) is quite common, with  estimates ranging from  between 6 to 13% of the population experiencing some form of SAD.  Light therapy is one of the most effective treatments we know of for seasonal affective disorder. Although  research on light therapy for seasonal affective disorder is limited, it is hypothesized that light therapy positively impacts melatonin as well as serotonin levels.  As natural light decreases with the seasonal change from fall to winter some are more sensitive to this shift, leading to alterations in circadian rhythm, which can impact energy level, eating behaviors, and motivation.   

It is important to stay consistently active throughout the year. Just because the days are getting shorter and colder does not mean that a long walk would not do your body and mind good. You need not enter hibernation mode as winter approaches. The more active you stay during the day and the more contact that you have with natural light the more regulated your circadian rhythm will be, which assists in keeping seasonal affective disorder at bay.
Some people have more of a biological tendency to experience seasonal affective disorder. There is no shame in getting  therapeutic assistance from the sidelines. Cognitive  behavioral therapy (CBT) is affective in addressing Mal adaptive thoughts and ineffective behaviors that may be contributing to seasonal affective disorder.  Each season offers moments of beauty and possibility for joy. You need not  let seasonal affective disorder get in the way of living life to the fullest. 
Speak to your healthcare provider if symptoms such as changes in sleep, appetite and energy level are noticeably shifting with winter approaching.
