Daylight Saving Time (DST) was introduced to better use daylight during the longer days of spring, summer, and early fall. By setting clocks forward an hour in the spring and back an hour in the fall, people can have more daylight in the evening and potentially use less energy on artificial lighting.
However, DST ending can have several impacts on mental health, especially during the transition period. Moving clocks forward by an hour disrupts sleep schedules, creating a form of "social jet lag" that can lead to sleep deprivation. Poor sleep quality or reduced sleep can increase irritability, affect concentration, and even heighten symptoms of depression and anxiety. DST adjustments can also interfere with our body's internal clock, or circadian rhythm, closely tied to mood regulation.
Research has shown that depressive symptoms tend to spike after the shift, likely due to a combination of sleep disruption and circadian misalignment. For those prone to Seasonal Affective Disorder (SAD), DST can be incredibly challenging, particularly in the fall when the "fall back" shift leads to shorter daylight hours in the evening. The earlier onset of darkness can intensify feelings of fatigue, lethargy, and depression associated with SAD.
To help manage the mental health challenges associated with DST, you can introduce a range of therapeutic coping skills and strategies designed to support better mood regulation, reduce stress, and improve sleep quality. Here are some suggestions:
Light Exposure: Exposure to natural light in the morning can help reset the body's internal clock. Spend time outside in the morning or sit by a window with natural light shortly after waking. For those who struggle to access natural light, using a light therapy box can be helpful, particularly for those with Seasonal Affective Disorder (SAD).
Mindfulness and Relaxation Techniques: Mindfulness exercises, such as deep breathing, progressive muscle relaxation, and guided imagery, can help reduce stress and anxiety related to DST changes. These practices can help you wind down before bed and reduce racing thoughts that might interfere with sleep.
Physical Activity: Physical activity, especially in the morning or early afternoon, can help regulate mood, improve sleep quality, and increase energy levels. Even a 20-30-minute walk can boost mood and reduce feelings of fatigue and lethargy. However, avoid intense exercise too close to bedtime, which can interfere with sleep.
Limit Caffeine and Alcohol: Caffeine and alcohol can disrupt sleep quality and contribute to feelings of anxiety or irritability. Monitor your intake, especially on the days surrounding the DST shift, and avoid caffeine in the late afternoon or evening.
Routine and Structure: Maintaining a stable daily routine around sleep, meals, exercise, and relaxation times can provide a sense of predictability, which can reduce stress. Stick to a consistent schedule as much as possible, especially during the adjustment period.
Self-Compassion and Patience: Remind yourself that it's normal to feel a bit "off" following a DST shift and that self-compassion can help. Be gentle with yourself, acknowledge any temporary struggles, and use kind, supportive self-talk as you adjust.
Using these strategies, you can approach DST changes with more confidence and resilience, better managing the temporary challenges and minimizing the impact on their mental health.
