As the days grow shorter and the nights grow longer, many of us begin to feel the effects of the changing seasons. In the UK, autumn and winter bring colder weather, less sunlight, and often a dip in mood that feels as inevitable as the autumn leaves falling. For some, however, these seasonal changes trigger a more serious condition known as Seasonal Affective Disorder (SAD). SAD is a type of depression that typically begins in the autumn and continues through the winter months, only to lift as spring approaches.
In this article, we’ll explore the symptoms of SAD, its causes, and, most importantly, how you can address it before it starts to affect your quality of life.
What is Seasonal Affective Disorder?
Seasonal Affective Disorder (SAD) is a type of depression typically manifesting during the autumn and winter months when natural light is limited. The lack of sunlight can interfere with the body’s circadian rhythms and diminish serotonin levels. As a result, many may experience a range of symptoms including low mood, fatigue, irritability, and anxiety due to insufficient light and serotonin.
The symptoms of SAD can vary:
– Elevated feelings of sadness or depressive mood
– Lack of interest in activities that were previously enjoyed
– Lack of concentration and limited decision-making
– Craving of sugary foods, high-carb foods and possibly weight gain
– Regularly withdrawing from social interactions and preferring to be in your own company
If you notice that these symptoms tend to reappear each autumn or winter, they could indicate the presence of SAD.
Recognising the Early Signs
One of the key ways to manage SAD is to recognise the symptoms before they fully take hold. Awareness is the first step in prevention. If you start to feel fatigued, low in energy, or generally more irritable as the seasons change, consider whether these feelings are part of a pattern.
Keep a journal to track your mood throughout the year, especially as autumn begins. Noting your energy levels, social engagement, and sleep patterns can reveal trends that might indicate SAD. For example, if you notice a recurring drop in energy and motivation from October through March, you may be experiencing early signs of the disorder.
It can also help to ask family and friends if they’ve noticed any changes in your behaviour during the colder months. Sometimes, those close to us see shifts we might miss ourselves.
Why Does SAD Happen?
There isn’t a single cause of SAD, but research points to a few major factors:
Reduced Sunlight
Sunlight helps regulate our biological clock (circadian rhythm), which in turn affects our mood, sleep, and overall well-being. With the reduced number of daylight hours, the body can often find it difficult to keep this clock on track.
Melatonin and Serotonin Levels
Melatonin, the hormone that regulates sleep, and serotonin, the hormone linked to mood, are hugely affected by sunlight. As the days shorten, the body is likely to alter the levels it produces, which can lead to disrupted sleep patterns and shifts in mood stability.
Proactive Ways to Address SAD Before It Starts
The good news is that you don’t have to wait until SAD affects your life to take action. By preparing in advance, you can reduce the risk of severe symptoms and keep yourself feeling positive and energised through the darker months.
1. Embrace Natural Light
Take every opportunity to get outside, especially in the morning when daylight has the most impact on your body’s clock. A morning walk can help lift your mood, as well as improve your energy levels for the day. Even brief exposure to natural light can make a difference, so try to get outside for at least 30 minutes a day.
2. Consider Light Therapy
Light therapy boxes mimic natural sunlight, helping to stimulate serotonin production. Spending 20-30 minutes each morning in front of a light therapy box can have a significant impact on mood and energy. When choosing a light therapy box, ensure it’s designed for SAD treatment and provides the recommended 10,000 lux intensity.
3. Maintain a Healthy Diet
As SAD can increase cravings for sugary and high-carb foods, maintaining a balanced diet is essential. Aim for a diet rich in fruits, vegetables, whole grains, and lean proteins. These foods provide steady energy, which can help combat the lethargy that often accompanies SAD. Omega-3 fatty acids found in fish, nuts, and seeds are also known to improve mood.
4. Stay Physically Active
Exercise is a powerful tool against depression. Regular physical activity boosts endorphins and serotonin levels, lifting your mood and enhancing overall well-being. Aim for at least 30 minutes of moderate exercise most days of the week. Activities like yoga and swimming are also beneficial for their calming and grounding effects.
5. Keep a Consistent Routine
Having a regular sleep and wake schedule can help your body regulate melatonin production. Go to bed and wake up at the same time each day, even on weekends, to keep your circadian rhythm stable. Limiting screen time before bed and creating a calming bedtime routine can also improve sleep quality, reducing fatigue and irritability.
When to Seek Professional Help
While self-care practices can effectively manage mild cases of SAD, sometimes professional support is needed. If you’re finding it difficult to function, or if your symptoms persist despite trying these strategies, consider reaching out to a mental health professional. Therapies like Cognitive Behavioural Therapy (CBT) have been shown to be effective in treating SAD, helping you develop coping strategies tailored to your needs.
Worried about SAD?
Seasonal Affective Disorder can be challenging, but it doesn’t have to control your life. By recognising the early signs and proactively addressing your mental health, you can protect yourself from the effects of SAD and continue to enjoy each season. Embracing a routine of light exposure, exercise, a balanced diet, and support can make a world of difference as you navigate the darker months. Remember, seeking help is a sign of strength, and with the right support, you can manage SAD before it takes hold. Book an appointment with Belinda here.
