As winter sets in, many individuals grapple with the 'winter blues,' often indicative of Seasonal Affective Disorder (SAD). This form of depression is typically triggered by the reduction in daylight hours, impacting the body's circadian rhythm and neurotransmitter levels, such as serotonin and melatonin. Key symptoms include persistent sadness, loss of interest in activities, changes in appetite and sleep patterns, low energy, difficulty concentrating, and irritability. Effective coping strategies are crucial for managing SAD and maintaining well-being throughout the winter months.
