It's a time of year when many of us can get down in the dumps, and Seasonal Affective Disorder is likely to blame.
Gloria Van Eek-Meijers is Deputy CEO at Waterloo Public Library - which is trying to help.
She said they set up SAD lights at their three locations just ahead of the Christmas holidays.
"At our main library - we put out desk lights, we have a lot of students that spend a lot of time there. So we thought the desk versions where they study would be a good place for that. At our other two branches - we have stand-up lights in our lounge areas."
If you've never heard of them before - SAD lights are essentially therapy lamps that produce a very bright light.
"The light closely resembles the natural sunlight that we experience in the spring and summer. In the fall and winter, when the light is much lower - the lamps will kind of provide that level of light, and boost mood and energy levels."
Van Eek-Meijers said they've already received some positive feedback.
"We actually received a comment on December 1 during the University exam time - we heard from someone that their daughter was at our main branch to study for exams, and found the light therapy lamp to be really helpful. She appreciated it being available during those dark days, and stressful times - so that was great reinforcement for us."
It's not just visitors who are able to feel the benefits either - as WPL also purchased SAD lamps for their staff areas.

It seems to be a sun-starved start to the winter. SAD lights are now available at all WPL locations for customers to use free of charge. Reservations are not required.
