It is well known that bright-light therapy can bring quick benefits to people with depression or SAD, because light affects the melatonin-serotonin system and elevates mood. Actually sunlight is effective at improving happiness levels for those with SAD or Seasonal Affective Disorder, a condition where people get clinically depressed in the winter because there is less sunlight. Light therapy, which mimics sunlight, is also effective. In fact, light therapy and sunlight are helpful with depression in general.

I can understand you! But everyone expects a sunny day after a gloomy weather! And enjoy this phenomenon! The soul becomes more fun!

''Why does sunshine make me happy?'' Tasty, tasty vitamin D!!

I have no idea, but sun shine makes me sad! Well not now in the autumn, but in the summer, 35++ degrees, the burning torturer! I could do without that guy!
