Fortunately, there are ways to beat the gloom, beyond buying a one-way ticket to Miami. We contacted a basket of experts -- including the man who first discovered SAD -- for advice on how to combat the winter funk. So rise and shine; it's time to bring the sunshine back!
The SAD specialist
The major cause of SAD is lack of light. So my advice to sufferers is simple: Get more light! You can do this by walking outdoors (especially in the morning), bringing more light into your home, or using special light fixtures. If you opt for light therapy fixtures, remember that bigger is often better, mornings are usually the best time to use the lights, and you needn't stare at the light -- just sit in front of it with your eyes open. Light therapy usually works within four days or so. -- Dr. Normal Rosenthal, author of Winter Blues: Everything You Need to Know to Beat Seasonal Affective Disorder.
The Yoga instructor
When posture improves, so does confidence. People who feel down have slumped shoulders, a collapsed chest and a tendency to look downward. This posture puts pressure on the heart and stops the diaphragm from moving freely. Yoga postures increase blood flow, which flushes the muscles, organs and glandular system of waste while delivering oxygen and nutrients. They also soften the muscles, allowing the energy lines of the body to open and restoring balance to your nervous system. -- Ducky Punch, founder of Yummy Yoga
Try St. John's Wort, which serves as a tonic for the nervous system and balances mood. Ashwagandha helps you cope with stress and environmental changes, and astragalus restores energy and helps prevent lethargy. You can also try certain vitamin supplements. B6 will help with mood, as will vitamin E. Magnesium is good for anxiety, insomnia and winter aches. -- Dr. Kathia Roberts of the Seasonal Health Wellness Center
The life coach
Tell the truth. When the seasons change, be honest about what makes you happy and go after it. For example, when mornings get cold and dark, you might be inclined to hide from life under your blankets. But if what actually makes you happy is to get your blood flowing, then that's what you must do. The no-snooze-button rule is a good one. -- Will Craig, director of educational programming at the Handel Group
The personal trainer
When we are physically fit, we manage stress better. The most effective way to get out of a rut this winter is to work out. Most any kind of exercise will help, from Pilates to cardio, just as long as you're physically active. Like the quote says: "If it's physical, it's therapy!" I recommend a strength-training program since it naturally increases your body's testosterone levels, which will increase your feelings of well-being and confidence. -- Kevin Kohout at Personal Trainer Los Angeles
