How to Keep the Winter Blues Away

After we have pushed our clocks back, the days become shorter and colder. The shorter days give us less contact time with the sunlight. Also, the sun is not out as often as it was in the other times of the year. All this lack of sunlight leads to feeling tired, depressed, irritable, and lack of motivation. To combat the mood and energy changes I have made a list of ways that can help improve your mood and prevent you from feeling the effects of the lack of sunlight. This is all a natural occurrence that some people feel more severely than others. Our bodies have evolved to slow down when food and resources start to become scarce. Think of bears hibernating.

1. Make sure you keep up your physical activity. You should be maintaining your exercise routine and taking advantage of the winter weather. Even though it is cold outside there are multiple ways to enjoy the outdoors. You can go snowboarding, skiing, snowshoeing, and sledding. In a study that Dr. Sibold conducted at the University of Vermont’s Rehabilitation and Movement Science department he found that exercise boosts mood up to 12 hours after only a 20 minute moderate intensity (~60% of max heart rate) cycling session.

2. Staying away from simple carbohydrates. Simple carbohydrates such as refined sugars (candy, soda, hot chocolate, etc) and white flour (cake, brownies, white bread, etc) are quickly digested by your body and cause your blood sugar levels to quickly spike up. When your blood sugar levels spike up, your body responds by releasing insulin. Because your blood sugar levels spike up so much quicker and higher when consuming simple carbohydrates your body releases a lot of insulin, which causes your blood sugar level to drop very quickly. This quick drop in blood sugar levels causes you to feel tired, irritable, and hungry, which is not how you want to feel when you are already tired and irritable due to the lack of sunlight. What happens is your body goes into the stress response called “flight or fight” mode. To prevent this up and down of blood sugar levels try to stick to complex carbohydrates by switching out white flour products for whole grain (including whole wheat products), such as using brown rice instead of white rice, whole wheat pasta instead of regular pasta, and whole wheat bread instead of white bread. Also, try to switch out sugar with honey, agave nectar, or sucanat to prevent that up and down affect. I want you to realize that these are not calorie free sweeteners, they just do not metabolism the same way sugar does. You can use calorie free sweeteners (such as splenda) as substitutes, but not all of them are good for baking. If you are baking during this holiday season try to switch out the sugar and flour with its healthier version.

3. Make sure you get enough sleep. With all of the parties and family gatherings to prepare for during the next couple of months you are running around, staying up late, over booking your schedule, etc. Therefore, you need make sure you are getting enough rest, so you don’t run yourself down. Sleep allows your body to repair itself from the day and recharge. If you want to keep your energy up through out the months, you need that sleep. If you are finding you are not able to get enough sleep at night try taking a power nap (20 minutes or less) during the day.

4. Don’t skip meals! I realize you are busy and there is so little time and so much to do, but you NEED to eat! This goes back to the blood sugar roller coaster. When you skip meals you allow your blood sugar levels to get low. By making sure you are eating meals or small meals through out the day you allow your blood sugar levels to stay stable, so your energy levels and moods aren’t all over the place. Another problem with skipping meals is that your metabolism slows down. With all calorie dense foods around you during these months, that is the last thing you want.

Even though it is cold and dark outside make sure you are getting out and doing things. The last thing you want to happen during the fall/winter months is to stay cooped up inside. Go enjoy the festivities of what the holidays have to bring!
