Winter Depression: Understanding SAD Symptoms, Causes & Treatment

• Seasonal Affective Disorder (SAD) is a form of depression linked to changing seasons, most common in late autumn or winter due to shorter days and reduced sunlight affecting brain chemistry.
• SAD is caused by disruptions to the body's circadian rhythm, a drop in serotonin levels, and a rise in melatonin, all influenced by reduced natural light.
• Symptoms include persistent low mood, excessive sleepiness, loss of interest, increased appetite (especially for carbohydrates), difficulty concentrating, and social withdrawal.
• Treatment and prevention strategies for SAD include light therapy, regular outdoor daylight exposure, psychotherapy, vitamin D supplementation, and maintaining a consistent winter routine.
