The holidays can be difficult, especially if you're experiencing anxiety. Time that is meant to bring joy and happiness may feel stressful and lonely. Anxiety can be either chronic (ongoing and long-term) or seasonal. Seasonal anxiety often starts in the fall and continues throughout the winter. Reduced sunlight can cause a drop in your brain's serotonin and melatonin levels, which disrupts your mood and sleep patterns. Even though seasonal anxiety is temporary, it is no less serious than chronic anxiety and if you see symptoms in yourself, you should schedule an appointment to talk with your primary care physician (PCP).
