Despite the overall success of cognitive-behavioral interventions in treating symptoms across mental conditions, but mindfulness-CBT (MCBT) have not been shown to prevent the onset of SAD when administered during the spring. This ineffectiveness may be because of subjectively different mindsets from winter to spring, with perceived severity and relevance of SAD being lower outside of the winter season as well as the lack of distinct lighting changes associated with winter. 

Effectiveness and Limitations of Preventative Interventions for SAD

Considering decreased mindfulness during winter time and the impact of underlying thought patterns on SAD symptomatology, potential solutions include mindfulness training at the beginning of the season focused on maintaining awareness of wellbeing and thoughts during weather changes, staying engaged with the surrounding environment despite decreased daylight, and using a benefit-seeking mindset during winter to enjoy seasonal features.

Seasonal depression, also known as Seasonal Affective Disorder, is a common and reoccurring condition impacting mood and energy level during seasonal changes. According to research, these behavioral changes in response to the environment are correlated with differing seasonal mindsets.

Seasonal Affective Disorder

While the term originates in Buddhism, the concept of mindfulness has grown to describe a general state of consciousness in which a person is more aware and accepting of their physical senses and thoughts in the present moment. Practicing mindfulness is believed to help alleviate mental suffering.

Mindfulness

People with SAD tend to report lower levels of mindfulness during the winter time compared to other seasons across a span of 2 years. This qualitative difference in the trajectory of SAD has been attributed to increased neuroticism about environmental changes. A theory pertaining to the origin of SAD is the dual vulnerability theory.

SAD Interventions Using Mindfulness and Mindset

While SAD can evoke depressive symptoms, people who indicated on the Winter Mindset scale that they enjoyed winter as a season, including the the activities and light levels associated with it, also had higher scores on measures of life satisfaction and subjective well-being. Enjoyable aspects of winter include: winter activities, natural beauty, soft light, and coziness. 

Positive Winter Mindset and SAD

People who indicate winter as a season personally associated with darkness, sadness, lethargy were more likely to be less satisfied with life overall and have lower levels of subjective wellbeing. Whereas two people in the same environment may experience the same things, their perceptions may differ based on a factors like attitudes and beliefs. Research suggests there is a mediating psychological factor of mindset on seasonal mood, and by extension, SAD outcomes.
