Winter depression (or winter blues) is a common affliction (折磨) for those who live in our northern climate. Its clinical name is seasonal affective disorder (or SAD) and up to 5% of the population (especially in northern states) may suffer from it. Seasonal affective disorder is characterized by feelings of sadness and depression that occur in the winter months when the temperatures drop and the days grow short . The depression is often associated with excessive eating or sleeping and weight gain. Women are twice to three times more likely to suffer from the winter blues than men.
There are many effective treatments for winter depression, some of which you can do to help yourself. Increasing your daily exposure to as much natural light as possible can be helpful to many. Any time that you have the opportunity to gain access to more sunlight in the winter months, you should try to do so. Taking walks throughout the day (even if you don’t normally do so), sitting next to a south-facing window at your office, in a classroom, or at home will increase your sunlight exposure. Exercising next to a window or outdoors (when possible) is another activity that can help.
Although it may be difficult to do, maintaining your schedule and lifestyle will help to keep the depression at bay. A regular pattern of sleep is the most important thing to maintain. It may be helpful, for instance, to have your bedroom lights on a timer to turn on a half-hour before you wake. This may help in waking at a regular time every morning, when it is still dark outside in the winter months.
Light therapy has shown to be an effective treatment for seasonal affective disorder. While you can purchase expensive, specialized light therapy lighting fixtures for your home or office, some inexpensive alternatives are also available. Another lighting technique to try is to replace commonly used light bulbs in your home with brighter full spectrum (also known as broad spectrum) light bulbs. While more expensive than regular light bulbs, these bulbs provide light that is similar to natural sunlight.
If none of these techniques seem to help your depressive symptoms, you should consider consulting your family physician or a mental health professional. The winter blues are a form of depression and can be readily treated w ith medications or psychotherapy when other self-help methods aren’t effective. Don’t be afraid to talk about this condition with a professional; it’s nothing to be ashamed or afraid of. With a little effort, the winter blues can be beaten
