More specifically, it’s a form of depression that’s related to seasonal changes.The reality is, that in Australia where our seasons are not really that extreme, there’s limited evidence for SAD. Nonetheless, there’s no doubt some people experience lower moods through the winter months" In this article, Dr. Happy describes the signs and symptoms to look out for and provides the best strategies you can follow to help improve your mood.
