As the colder months approach, many people experience tiredness, irritability, and a lack of interest in things they normally enjoy. These symptoms may be indicative of Seasonal Affective Disorder (SAD), a type of depression that is more likely to affect women than men. SAD is caused by a lack of daylight, which can disrupt the body’s internal clock and serotonin levels. Symptoms of SAD include depression, irritability, difficulty concentrating, and disruptions in sleep and eating habits. However, SAD is highly treatable, and there are various coping mechanisms to ease its effects. Light therapy, medication, supplements, and engaging in enjoyable activities during the winter months can all help manage symptoms of SAD. It’s also important to maintain social connections and challenge negative thoughts about winter. With the right treatment and support, there is hope for overcoming SAD.
