Seasonal mood disorder, also known as seasonal affective disorder (SAD), is a condition in which an individual experiences depressive episodes during a particular season, most commonly winter. Antonyms for seasonal mood disorder include cheerfulness, happiness, joyfulness, and liveliness. Individuals who do not experience seasonal mood disorder may feel energized, enthusiastic, and excited during the winter months, or any other season for that matter. These individuals often have a positive outlook on life, enjoy engaging in activities, and feel content with their daily routine. While seasonal mood disorder can be challenging to manage, incorporating healthy habits such as exercise, staying engaged in hobbies, and spending time with loved ones can help alleviate symptoms.
