Each fall, the drop in light is accompanied, for some people, by a drop in morale, fatigue and a desire to sleep and eat more. This disorder, called seasonal depression, is very real and linked to lack of light. Good news: it can be understood and treated.
1. A disorder punctuated by the seasons
Seasonal depression is a form of depression that occurs recurrently at the same time, most often in fall and winter, then subsides in spring. It is more common in regions where winter is long and not very sunny.
2. The central role of light
Light regulates our internal clock and the secretion of melatonin, the sleep hormone. Lack of winter light disrupts these rhythms, which influences mood, energy and sleep. This is why the symptoms are often particular.
| Symptom | Seasonal feature |
|---|---|
| Sleep | Need to sleep more |
| Appetite | Craving for sweet and starchy foods |
| Energy | Marked fatigue, slowdown |
| Mood | Low morale in winter |
3. Light therapy and other solutions
The standard treatment is light therapy: daily exposure to intense light, in the morning, using a suitable lamp. Exposing yourself to natural light, going out during the day and maintaining physical activity also help.
- Expose yourself to daylight, especially in the morning
- Consider light therapy on medical advice
- Move regularly and maintain a stable pace of life
4. When to consult?
If the winter drop in morale is slight, these measures are often enough. But if the symptoms are severe, recur every year or have a strong impact on daily life, it is important to consult: suitable treatment is available.
Recognizing the seasonal nature of this discomfort allows us to anticipate and better get through the winter.
