A. We all know that exercise can be an effective method of “having your cake and eating it, too” (as long as eating it doesn't become a regular habit in our diet) and not gain weight. The short days of sunlight and cold temperatures are often deterrents for exercising in the winter.

Here are some thoughts to consider.
Research has shown that cold temperature itself is a positive stimulus for raising our metabolism and burning calories. Exercising in the cold is a “plus.”

Dressing warmly, but not overdressing is important. If body heat can't escape easily, our ability to exercise for 30 minutes can be difficult, and possibly unhealthy. Exercise in the daylight. If snow is on the ground - even better. Research has shown that when we do moderate exercise in bright light there is greater fat loss than in low illumination. Also, exercising in those conditions greatly improves our mood! So, let this season find you in good health and happy spirits.
