Outlook Is Getting Sunnier

By Dr. Brian McDonough, Medical Editor

PHILADELPHIA (CBS) - It is hard to believe...this is the last day of February. I think I am not alone when I say that we have had our fill of snow, black ice, traffic jams, dreary days and you know the rest.

This is not to say that we are heading straight to 70-degree temperatures but the fact that we are starting to have longer days along with some moderation of temperatures means that many of us are due for a mood lift.

This change in mood is part reactionary to the change in temperatures and part physiological because of increased sunlight.

The bottom line is that we are getting closer to exercising outside and not worrying about a snowstorm during rush hour.

Don't you feel better already?
